Canyon in the Virgin Mountains of Clark County, Nevada. Name does not appear in the GNIS nor does it appear on maps published since the 1950's. I have also reviewed the geological literature published since 1950, and found no references to the canyon by name.

"Yant" is a Piute name for Agave deserti or A. utahensis, so this name refers to a canyon with a lot of agave roasting pits.

Philip A. Munz and a graduate student, N. C. Sweet, collected in this canyon on 4 June 1941, collecting several species of interest. There is a rare bryophyte, Trichostomum sweetii (E. B. Bartram) L. R. Stark, that Sweet collected. There is rare form of Agave utahensis collected by P. A. Munz. And, there is a collection Swertia albomarginata that attracted my interest.

Quoting from Stark (2007):

Two main canyons enter the Virgin Mountains on the south side; both are unnamed on any official map. One of these is the obvious entry point for Munz’s group since it has a road most of its length and was the site of the “Nay Summer Camp.” This area is called “Nay Canyon” in Armstrong’s thesis and has many of the plants collected by Munz on his trip as well as good bryophyte habitat on the north-facing slopes. It is a bit puzzling though, because it does not have an obvious “east fork” at the elevations listed by Munz. Another canyon with no name parallels “Nay Canyon” just to the west. This other canyon is also promising because it has a more obvious “east fork” and while it remains roadless it is still relatively accessible. Also, according to W. Niles (personal communication) “Yant Pit Canyon” may be one of the lower canyons in that area and is probably not the same as "Nay Canyon.”
