Dominguez Canyon is part of the Dominguez-Escalante National Conservation Area south of Grand Junction, Colorado. It is so name since it was first "discovered" by the Dominguez–Escalante expedition in 1776. The canyon is incredibly beautiful with the Gunnison River slicing through the middle of it and canyon walls rising up on either side. The canyon is also home to quite a few petroglyphs; both "modern" from the Utes around 200 years ago, and "prehistoric". Petroglyphs depicting horses are modern, since horses didn't appear in the Americas until the Spanish arrived.
