Colorado shares part of Hovenweep National Monument, the majority of which is in Utah, but its most well-known site, the only American national park to contain ancient remains rather than natural landscapes, is Mesa Verde, occupying a number of deep canyons separated by thin mesas, on high elevation land south of the San Juan Mountains.
Snow closes much of the park for nearly half the year, but in summer the ruins are extremely popular, even though very few are open to close-up exploration.
Long before Euro-Americans entered the Great Basin, substantial numbers of people lived within the present boundaries of Utah. They occupied an area mainly north and east of the state, yet periodically utilized subsistence ranges in Utah.
Archaeological reconstructions suggest human habitation stretching back some 12,000 years. The Goshute (Kusiutta) inhabited the inhospitable western deserts of Utah.
The other major groups are the Sevier, Fremont, Sinagua, Salado, Hohokam and Mogollon (see map).

Joyce gained a respect for business from her father, Norris, who was a realtor, escrow broker, and owner of multiple rental properties before his passing.
In the Four Corners states the NPS maintain 19 such locations, most featuring the remains of ancient villages (pueblos) which are sometimes built on mesa tops or open plains but more usually are found in alcoves in sandstone canyons, known as cliff dwellings.
Other evidence of the former civilizations comes from rock art, either etched into the dark patina on the weathered surface of exposed rocks (petroglyphs) or created by painting onto the rocks using variously colored pigments (pictographs).
