The San Juan Expedition (also known as the San Juan Mission or the Hole-in-the-Rock Expedition) was a group of Mormon settlers intent on establishing a colony in what is now southeastern Utah, in the western United States. Their difficult passage through the deep canyons of the Colorado River represents the ingenuity and determination needed during the country's era of western exploration and settlement.
