Llano Estacado?

The Llano Estacado is a mesa according to its article. It dwarfs the Grand Mesa. Is there a good reason to not call the Llano Estacado the largest mesa in North America?--Dwane E Anderson (talk) 01:27, 13 December 2008 (UTC)[reply]

I question the wording of the current version that "This volcanic layer, created during the birth of the modern Rocky Mountains approximately 30 million years ago, suppressed erosion compared to the surrounding sedimentary rock layers..." It has commonly been stated in the local area, for many years, that there was a basalt flow through fissures ~10 million years ago that created the modern layer of basalt that caps the Grand Mesa. It is more believable that the basalt is 10 million rather than 30 million years old. Please comment, professional geologist or peer-reviewed literature comments wanted and needed.

Apparently this article has had an error in it from the beginning (2005!) regarding the age of the basalt. From the GSA Meeting Abstract of Cole & Weston (2007), who probably actually have been there: "Grand Mesa is a prominent east-west landform capped by basalt (published argon-argon dates of 9.22 to 10.76 Ma; average = 9.92 Ma". Translation: The rock is 10 million years old.Jack B108 (talk) 16:10, 12 August 2009 (UTC)[reply]

Flat-top mountain

I am also sceptical of the "world's largest" claim. If you consider any largely flat elevated area then surely the Tibetan plateau (2,500,000 km2) is the obvious contender. If not, then what is the key distinction? — Preceding unsigned comment added by Almonaster (talk • contribs) 09:10, 21 September 2017 (UTC)[reply]
