Notes

after some discussion with several rattlesnake researchers Louis Porras, Brendan O'Connor, Rich Gassaway, Gordon Schuett, the concensus is that this snake is abyssus rather than concolor due to the location near Escalante (the DNA for snakes there during several studies came back as abyssus clade) and the extremely long tail is indicitive of Utah abyssus.

there are no prairie rattlers on the west side of powell or in garfield county, and to be frank, it doesn't look like a prairie at all. The only consideration is between Grand Canyon rattlesnakes and Midget faded in this area of Utah.

i beg to differ i believe this to be a prairie rattler, the locale is too far north and east for Abyssus
