The Oregon Trail passed over the ridge to the east of Devil's Gate. Good grass, water and the shelter of the hills made this a popular campsite.
Explorer Brevet-Captain John C. Fremont, 1842:
"In about three miles, we reached the entrance of the canyon when the Sweet Water issues upon the more open valley we had passed over. The usual road passes to the right of this place... Wilderness and disorder were the character of the scenery..."
Oregon emigrant James Mathers stopped here July 8, 1846, and wrote:
"...encamped above the pass of the river, between high rocks. This is the most interesting sight we have met with on our journey."
Later, the Mormon Pioneer Trail and the California and Pony Express Trails came over this same ridge. Some 500,000 emigrants followed the Trail west. Many travelers called it the Emigrant Road.
