San Juan County is a county located in the southeastern portion of the state and was named by the Utah State Legislature for the San Juan River, itself named by Spanish explorers in honor of Saint John. San Juan County borders Arizona, Colorado, and New Mexico at the Four Corners. The county's western and southern boundaries lie deep within gorges carved by the Colorado and San Juan Rivers. Tributary canyons, cutting through rock layers of the surrounding deserts, have carved the land up with chasms, cliffs and plateaus. In the center of the county are Cedar Mesa, Comb Wash, Natural Bridges and Hovenweep National Monuments. Canyonlands National Park is primarily within the county borders. The Eastern side of Glen Canyon National Recreation Area / Lake Powell in also in San Juan County.
