Hovenweep National Monument protects five prehistoric,
Puebloan-era villages spread over a twenty-mile expanse of mesa tops and canyons along the Utah-Colorado border. There are two Colorado entrances to the monument, both near
Cortez. The monument consists of six separate groups of prehistoric Pueblo Indian ruins: The Square Tower Ruins, the best preserved and most impressive and the Cajon Ruins in Utah, and the Holly Ruins, Hackberry Canyon, Cutthroat Castle and Goodman Point Ruins in Colorado. The Square Tower Group is the primary contact facility with a visitor center, campground and interpretive trail.
