Created fairly recently (2005), Ojito is one of New Mexico's lesser known wilderness regions, occupying 11,000 acres of the high desert west of San Ysidro, bordering the Zia Indian Reservation. This part of the state lies right at the edge of the Colorado Plateau, a vast area of layered sandstone rocks of different colors, and as with other nearby sections also protected as wilderness such as Ah-Shi-Sle-Pah, Bisti and De-Na-Zin, Ojito features beautiful eroded rock formations including hoodoos, caprocks, cliffs and solidified dunes, together with petrified wood and other fossils, plus occasional petroglyphs and ancient ruins. Unlike the more well known areas further northwest (all within the San Juan Basin), the Ojito Wilderness is more overgrown and less remarkable at first sight, as the interesting locations are generally small, isolated and take some effort to find - most of the region is a rather nondescript mixture of bushy flats, twisting ravines and low mesas, not much different to the land at either side, which is similar in appearance for a hundred miles or more in some directions. Perhaps the single most impressive site in the locality is just outside the wilderness - the San Ysidro Anticline, where the sandstone strata have been pushed up to create a 3 mile long band of colorful ridges and ravines.
Canyon de Chelly National Monument was established on April 1, 1931 as a unit of the National Park Service. Located in northeastern Arizona, it is within the boundaries of the Navajo Nation and lies in the Four Corners region. Reflecting one of the longest continuously inhabited landscapes of North America, it preserves ruins of the indigenous tribes that lived in the area, from the Ancestral Puebloans (formerly known as Anasazi) to the Navajo
