'''Black Canyon of the Gunnison National Park''' is an American [[national park]] located in western [[Colorado]] and managed by the [[National Park Service]]. There are two primary entrances to the park: the south rim entrance is located {{convert|15|mi|km}} east of [[Montrose, Colorado|Montrose]], while the north rim entrance is {{convert|11|mi|km}} south of [[Crawford, Colorado|Crawford]] and is closed in the winter. The park contains {{convert|12|mi|km}} of the {{convert|48|mi|km|adj=on}} long Black Canyon of the Gunnison River. The national park itself contains the deepest and most dramatic section of the canyon, but the canyon continues upstream into [[Curecanti National Recreation Area]] and downstream into [[Gunnison Gorge National Conservation Area]]. The canyon's name owes itself to the fact that parts of the gorge only receive 33 minutes of sunlight a day, according to ''Images of America: The Black Canyon of the Gunnison''. In the book, author Duane Vandenbusche states, "Several canyons of the American West are longer and some are deeper, but none combines the depth, sheerness, narrowness, darkness, and dread of the Black Canyon."<ref name="Vandenbusche 2009 7">{{cite book|title=Images of America - The Black Canyon of the Gunnison|last=Vandenbusche|first=Duane|date=2009|publisher=Arcadia Publishing|isbn=978-0-7385-6919-2|page=7}}<!--|accessdate= 2014-07-28--></ref>

===Precambrian===
The [[Precambrian]] [[gneiss]] and [[schist]] that make up the majority of the steep walls of the Black Canyon formed 1.7 billion years ago during a metamorphic period brought on by the collision of ancient volcanic island arcs with the southern end of what is present-day [[Wyoming]]. The lighter-colored [[pegmatite]] [[dike (geology)|dikes]] that can be seen crosscutting the basement rocks formed later during this same period.<ref>{{cite book |last=Tweto |first=O |authorlink=|title=Colorado Geology |publisher=Rocky Mountain Association of Geologists |year=1980 |pages=37–46 }}</ref>

===Cretaceous - Tertiary===
The entire area underwent uplift during the [[Laramide orogeny]] between 70 and 40 million years ago which was also part of the Gunnison Uplift. This raised the Precambrian gneiss and schist that makes up the canyon walls. During the [[Tertiary]] from 26 to 35 million years ago large episodes of [[volcanism]] occurred in the area immediately surrounding the present day Black Canyon. The [[West Elk Mountains]], [[La Sal Range|La Sal Mountains]], [[Henry Mountains]], and [[Abajo Mountains]] all contributed to burying the area in several thousand feet of [[volcanic ash]] and debris.<ref name="geosource">{{cite paper|author=Trista Thornberry-Ehrlich |title=Black Canyon of the Gunnison National Park & Curecanti National Recreation Area: Geologic Resource Evaluation Report |year=2005 |url=http://www2.nature.nps.gov/geology/inventory/publications/reports/blca_cure_gre_rpt_view.pdf |format=[[PDF]] |accessdate=2006-10-27 |deadurl=yes |archiveurl=https://web.archive.org/web/20061103160834/http://www2.nature.nps.gov/geology/inventory/publications/reports/blca_cure_gre_rpt_view.pdf |archivedate=2006-11-03 |df= }}</ref>

The modern Gunnison River set its course 15 million years ago as the run-off from the nearby La Sal and West Elk Mountains and the [[Sawatch Range]] began carving through the relatively soft volcanic deposits.<ref name="geosource"/>

===Quaternary===
With the Gunnison River's course set, a broad uplift in the area 2 to 3 million years ago caused the river to cut through the softer volcanic deposits. Eventually the river reached the Precambrian rocks of the Gunnison Uplift. Since the river was unable to change its course, it began scouring through the extremely hard metamorphic rocks of the Gunnison Uplift. The river's flow was much larger than currently, with much higher levels of [[turbidity]]. As a result, the river dug down through the Precambrian gneiss and schist at the rate of {{convert|1|in|mm|adj=on}} every 100 years. The extreme hardness of the metamorphic rock along with the relative quickness with which the river carved through them created the steep walls that can be seen today.<ref name="geosource"/>

A number of feeder canyons running into the Black Canyon slope in the wrong direction for water to flow into the canyon. It is believed that less-entrenched streams in the region shifted to a more north-flowing [[Drainage system (geomorphology)|drainage pattern]] in response to a change in the tilt of the surrounding terrain. The west-flowing Gunnison, however, was essentially trapped in the hard Precambrian rock of the Black Canyon and could not change its course.<ref>

== History ==
The [[Ute Tribe|Ute]] Indians had known the canyon to exist for a long time before the first Europeans saw it. They referred to the river as "much rocks, big water," and are known to have avoided the canyon out of superstition.<ref name="Vandenbusche 2009 7"/> By the time the United States declared [[United States Declaration of Independence|independence]] in 1776, two [[Spain|Spanish]] expeditions had passed by the canyons. In the 1800s, the numerous fur trappers searching for beaver pelts would have known of the canyon's existence but they left no written record. The first official account of the Black Canyon was provided by Captain [[John Williams Gunnison]] in 1853, who was leading an expedition to survey a route from Saint Louis and San Francisco.

In 1901, the [[United States Geological Survey|U.S. Geological Survey]] sent Abraham Lincoln Fellows and William Torrence into the canyon to look for a site to build a diversion tunnel bringing water to the Uncompahgre Valley, which was suffering from water shortages due to an influx of settlers into the area.<ref>{{cite journal |last= Frank |first= Jerritt |date= 2003-01-01 |title= Visions of the landscape : People, place and the Black Canyon of the Gunnison River |journal= University of Montana Scholarworks - Theses, Dissertations, Professional Papers |publisher= University of Montana |pages= 75–77 }}</ref> Torrence, a Montrose native and an expert mountaineer, had taken part in a failed expedition the previous year, and his experience proved valuable on his second excursion. He opted to bring a single rubber air mattress instead of the heavy wooden boats that had doomed his previous journey into the canyon. They entered the canyon on August 12 equipped with "only hunting knives, two silk lifeline ropes, and rubber bags to encase their instruments." After a harrowing 10 days braving rock falls, waterfalls, and 76 river crossings, they emerged from the canyon with a suitable tunnel site.<ref>{{cite book|title=Images of America - The Black Canyon of the Gunnison|last=Vandenbusche|first=Duane|date=2009|publisher=Arcadia Publishing|isbn=978-0-7385-6919-2|pages=35–54}}<!--|accessdate= 2014-07-28--></ref>

Construction on the tunnel began 4 years later, and was fraught with difficulties right from the onset. "Working conditions at the tunnel were difficult due to the high levels of carbon dioxide, excessive temperatures, humidity, water, mud, shale, sand, and a fractured fault zone...It took the tunneling crew almost one year to bore through 2000 feet of water-filled rock. The tunnel was driven through granite, quartzite, gneiss, and shale as well as layers of sandstone, coal, and limestone. Work on the Gunnison Tunnel was first done manually and by candlelight. One miner would hold the drill and rotate it while the second miner would use a sledgehammer to drive the drill into the rock. This work required strong, hard-working men. In spite of good pay and fringe benefits, most disliked the dangerous underground conditions and stayed an average of only 2 weeks." 26 men were killed during the 4 year undertaking. The tunnel was finally completed in 1909, stretching a distance of 5.8 miles and costing nearly 3 million dollars.

The line was built to provide a link to the burgeoning gold and silver mines of the San Juan mountains. The rugged terrain precluded using 4' 8 1/2" standard rail; Palmer decided to go with the narrower 3' gauge. It took over a year for Irish and Italian laborers to carve out a 15-mile roadbed from Sapinero to Cimarron, costing a staggering $165,000 a mile. The last mile is said to have cost more than the entire Royal Gorge project.<ref>{{cite web |title = Black Canyon of the Gunnison National Park : Narrow Gauge Railroad Through the Black Canyon |publisher = National Park Service |url = http://www.nps.gov/blca/historyculture/railroad.htm |accessdate = 2014-06-24}}</ref> On August 13, 1882, the first passenger train passed through the Black Canyon. The editor of the Gunnison Review-Press rode in one of the observation cars; he remarked that the canyon was "undoubtedly the largest and most rugged canyon in the world traversed by the iron horse. We had often heard of the scenery of this canyon, but no one can have the faintest conception of its grandeur and magnificence until they have made a trip through it. It is a narrow gorge with walls of granite rising in some places to a height of thousands of feet…Throughout its entire length there is probably not a quarter of a mile of straight track on it. It is a serpentine road in every respect and the curves are frequent and sharp. In hundreds of places the walls of granite are perpendicular and in many places the road bed is blasted out in the side of the walls of rock which overhang the track."

"Working conditions at the tunnel were difficult due to the high levels of carbon dioxide, excessive temperatures, humidity, water, mud, shale, sand, and a fractured fault zone...It took the tunneling crew almost one year to bore through 2000 feet of water-filled rock. The tunnel was driven through granite, quartzite, gneiss, and shale as well as layers of sandstone, coal, and limestone. Work on the Gunnison Tunnel was first done manually and by candlelight. One miner would hold the drill and rotate it while the second miner would use a sledgehammer to drive the drill into the rock. This work required strong, hard-working men. In spite of good pay and fringe benefits, most disliked the dangerous underground conditions and stayed an average of only 2 weeks." 26 men were killed during the 4 year undertaking.

The east end of the park, where it meets Blue Mesa Reservoir at Blue Mesa Point, is the area most developed for camping. It includes tent camping and RV camping with full hookups (private site), as well as canyon tours, hiking, fishing and boat tours. Nearby is the [[Curecanti National Recreation Area]] which includes a visitor center, marina facilities and, among 10 campgrounds within in the NRA, the Lake Fork Campground. The west end of the park has river access by automobile, as well as guided tours of the canyon. A short hike at Blue Mesa Point Information Center heads down to Pine Creek and the Morrow Point boat tours, boating, fishing and hiking. At the south rim there is one [[campground]] for tent and RV camping, one loop of which has electrical hookups, and several [[hiking]] and nature trails. The north rim is also accessible by automobile and has a small, primitive campground. Automobiles can access the river via the East Portal Road at the south rim; this road has a 16% grade and is prohibited to vehicles over {{convert|22|ft|m|0}} in length. [[File:Tps_-_Gunnison_Point.jpg|thumb|left|Gunnison Point Trail, South Rim]] The river can also be accessed by steep, unmaintained trails called "routes" or "draws" on the north and south rim. These routes require about two hours to hike down and two to four hours to hike back up, depending on which route is taken. All inner canyon descents are strenuous and require Class 3 climbing and basic route finding skills. Steep talus, impassable ledges, and lack of cover are some of the challenges hikers are faced with. Poison ivy also grows abundantly in the draws and on the canyon floor. Long sleeves and hiking boots are strongly recommended. The flow rate of the Gunnison River should also be considered for those planning on camping in the canyon, as high river levels can wash out the camp sites. The National Park Service warns the following: "Routes are difficult to follow, and only individuals in excellent physical condition should attempt these hikes&nbsp;... Hikers are expected to find their own way and to be prepared for self-rescue."<ref>{{cite web | title = Black Canyon of the Gunnison National Park : Hiking the Inner Canyon |publisher = National Park Service |url = http://www.nps.gov/blca/planyourvisit/hikinginnercanyon.htm |accessdate = 2014-07-29}}</ref> A free back country permit is required for all inner canyon use except at the west end. The Gunnison River is designated as a Gold Medal Water from 200 yards downstream of Crystal Reservoir Dam to the North Fork. This includes the 12 miles within the Black Canyon of the Gunnison National Park. Only artificial flies and lures are permitted, and all rainbow trout are catch and release.

The Gunnison River is primarily responsible for carving the canyon, though several other geologic events had to occur in order to form the canyon as it is seen today.<ref> {{cite web |title=Black Canyon of the Gunnison National Park- The Geologic Story |publisher=National Park Service |date=2006-07-25 |url=http://www.nps.gov/blca/naturescience/geology.htm |accessdate=2006-10-27}}</ref> [[File:Black Canyon Painted Wall.JPG|thumb|upright|Painted Wall—the tallest sheer [[cliff]] in [[Colorado]] at {{convert|2250|ft|m}}. Lighter-colored With the Gunnison River's course set, a broad uplift in the area 2 to 3 million years ago caused the river to cut through the softer volcanic deposits. Eventually the river reached the Precambrian rocks of the Gunnison Uplift. Since the river was unable to change its course, it began scouring through the extremely hard metamorphic rocks of first official account of the Black Canyon was provided by Captain [[John Williams Gunnison]] in 1853, who was leading an expedition to survey a route from Saint Louis and San Francisco. He described the country to be "the roughest, most hilly and most cut up," he had ever seen, and skirted the canyon south towards present-day Montrose. Following his death at the hands of Ute Indians later that year, the river that Captain Gunnison had called the Grand was renamed in his honor.<ref>{{cite web |title = Black Canyon of the Gunnison National Park : 1853 - Gunnison Expedition: |publisher = National Park Service |url = http://www.nps.gov/blca/historyculture/explorer_gunnison.htm |accessdate = 2014-07-28}}</ref> === The Denver & Rio Grande === In 1881, William Jackson Palmer's [[Denver and Rio Grande Railroad]] had reached Gunnison from Denver. The line was built to provide a link to the burgeoning gold and silver mines of the San Juan mountains. The rugged terrain precluded using 4' 8 1/2" standard rail; Palmer decided to go with the narrower 3' gauge. It took over a year for Irish and Italian laborers to carve out a 15-mile roadbed from Sapinero to Cimarron, costing a staggering $165,000 a mile. The last mile is said to have cost more than the entire Royal Gorge project.<ref>{{cite web |title = Black Canyon of the Gunnison National Park : Narrow Gauge Railroad Through the Black Canyon |publisher = National Park Service |url = http://www.nps.gov/blca/historyculture/railroad.htm |accessdate = 2014-06-24}}</ref> On August 13, 1882, the first passenger train passed through the Black Canyon. The editor of the Gunnison Review-Press rode in one of the observation cars; he remarked that the canyon was "undoubtedly the largest and most rugged canyon in the world traversed by the iron horse. We had often heard of the scenery of this canyon, but no one can have the faintest conception of its grandeur and magnificence until they have made a trip through it. It is a narrow gorge with walls of granite rising in some places to a height of thousands of feet…Throughout its entire length there is probably not a quarter of a mile of straight track on it. It is a serpentine road in every respect and the curves are frequent and sharp. In hundreds of places the walls of granite are perpendicular and in many places the road bed is blasted out in the side of the walls of rock which overhang the track." He went on to proclaim, "Another such a feat of railroad engineering probably can not be found in the world, and there is probably no section of Colorado or of the whole country where such a varied and interesting lot of scenery can be found."<ref>{{cite news |title= Black Canon - The First Passenger Train Through Sunday, August 13, 1882. |publisher= Gunnison Review-Press |page= 1 |date= August 14, 1882 }}</ref> [[File:Cimarron_Rail_-_theperfectstorm.jpg|thumb|left|Preserved rail bridge over Cimarron Creek]] In the hopes of running the railroad through the rest of the Black Canyon, Palmer sent his top engineer Bryan Bryant on an inner canyon exploration.

In addition, the canyon is the home of a number of resident birds including the [[American dipper]], two species of [[eagle]], eight species of [[hawk]], six species of [[owl]], and [[Steller's jay]] as well as migratory birds such as the [[mountain bluebird]], [[peregrine falcon]], [[magpie]], [[white-throated swift]] and [[canyon wren]].<ref>{{cite web | title = Black Canyon of the Gunnison National Park : Animals | publisher = National Park Service | url = http://www.nps.gov/blca/naturescience/animals.htm | accessdate = 2007-07-29 }}</ref> == Attractions == An annual average of about 190,000 tourists visited the park in the period from 2007 to 2016.<ref name="visits"/> The main attraction of the park is the scenic drive along US Highway 50 and Colorado Highway 92, as well as the south rim. The east end of the park, where it meets Blue Mesa Reservoir at Blue Mesa Point, is the area most developed for camping. It includes tent camping and RV camping with full hookups (private site), as well as canyon tours, hiking, fishing and boat tours. Nearby is the [[Curecanti National Recreation Area]] which includes a visitor center, marina facilities and, among 10 campgrounds within in the NRA, the Lake Fork Campground. The west end of the park has river access by automobile, as well as guided tours of the canyon. A short hike at Blue Mesa Point Information Center heads down to Pine Creek and the Morrow Point boat tours, boating, fishing and hiking. At the south rim there is one [[campground]] for tent and RV camping, one loop of which has electrical hookups, and several [[hiking]] and nature trails. The north rim is also accessible by automobile and has a small, primitive campground. Automobiles can access the river via the East Portal Road at the south rim; this road has a 16% grade and is prohibited to vehicles over {{convert|22|ft|m|0}} in length. [[File:Tps_-_Gunnison_Point.jpg|thumb|left|Gunnison Point Trail, South Rim]] The river can also be accessed by steep, unmaintained trails called "routes" or "draws" on the north and south rim. These routes require about two hours to hike down and two to four hours to hike back up, depending on which route is taken. All inner canyon descents are strenuous and require Class 3 climbing and basic route finding skills. Steep talus, impassable ledges, and lack of cover are some of the challenges hikers are faced with. Poison ivy also grows abundantly in the draws and on the canyon floor. Long sleeves and hiking boots are strongly recommended. The flow rate of the Gunnison River should also be considered for those planning on camping in the canyon, as high river levels can wash out the camp sites. The National Park Service warns the following: "Routes are difficult to follow, and only individuals in excellent physical condition should attempt these hikes&nbsp;... Hikers are expected to find their own way and to be prepared for self-rescue."<ref>{{cite web | title = Black Canyon of the Gunnison National Park : Hiking the Inner Canyon |publisher = National Park Service |url = http://www.nps.gov/blca/planyourvisit/hikinginnercanyon.htm |accessdate = 2014-07-29}}</ref> A free back country permit is required for all inner canyon use except at the west end. The Gunnison River is designated as a Gold Medal Water from 200 yards downstream of Crystal Reservoir Dam to the North Fork. This includes the 12 miles within the Black Canyon of the Gunnison National Park. Only artificial flies and lures are permitted, and all rainbow trout are catch and release. Additionally, fishing is prohibited within 200 yards downstream of Crystal Dam.<ref>{{cite news |last= Bulger |first= Amy |date= 2014 |title= Colorado Parks & Wildlife - 2014 Colorado Fishing |publisher= Colorado Parks and Wildlife |page= 21 }}</ref> [[File:Tps_-_East_portal.jpg|thumb|right|Gunnison River at East Portal]] The Black Canyon is a center for [[rock climbing]] in a style known as [[traditional climbing]].

In the 1800s, the numerous fur trappers searching for beaver pelts would have known of the canyon's existence but they left no written record. The first official account of the Black Canyon was provided by Captain [[John Williams Gunnison]] in 1853, who was leading an expedition to survey a route from Saint Louis and San Francisco. He described the country to be "the roughest, most hilly and most cut up," he had ever seen, and skirted the canyon south towards present-day Montrose. Following his death at the hands of Ute Indians later that year, the river that Captain Gunnison had called the Grand was renamed in his honor.<ref>{{cite web |title = Black Canyon of the Gunnison National Park : 1853 - Gunnison Expedition: |publisher = National Park Service |url = http://www.nps.gov/blca/historyculture/explorer_gunnison.htm |accessdate = 2014-07-28}}</ref>', 42 => 'In 1901, the [[United States Geological Survey|U.S. Geological Survey]] sent Abraham Lincoln Fellows and William Torrence into the canyon to look for a site to build a diversion tunnel bringing water to the Uncompahgre Valley, which was suffering from water shortages due to an influx of settlers into the area.<ref>{{cite journal |last= Frank |first= Jerritt |date= 2003-01-01 |title= Visions of the landscape : People, place and the Black Canyon of the Gunnison River |journal= University of Montana Scholarworks - Theses, Dissertations, Professional Papers |publisher= University of Montana |pages= 75–77 }}</ref> Torrence, a Montrose native and an expert mountaineer, had taken part in a failed expedition the previous year, and his experience proved valuable on his second excursion.

The tunnel was driven through granite, quartzite, gneiss, and shale as well as layers of sandstone, coal, and limestone. Work on the Gunnison Tunnel was first done manually and by candlelight. One miner would hold the drill and rotate it while the second miner would use a sledgehammer to drive the drill into the rock. This work required strong, hard-working men. In spite of good pay and fringe benefits, most disliked the dangerous underground conditions and stayed an average of only 2 weeks." 26 men were killed during the 4 year undertaking. The tunnel was finally completed in 1909, stretching a distance of 5.8 miles and costing nearly 3 million dollars.
