Arches National Park Trails Professional Review and Guide
"Arches National Park is located 5 miles north of Moab. Of the five national parks in Utah, Arches is the one most dominated by domesticated “frontcountry.” Nevertheless, park administrators now estimate that more than 70,000 acres have wilderness characteristics. The increase in recommended wilderness acreage comes from several sources, including the addition of Lost Spring Canyon’s 3,140 acres, expiration of some mineral and grazing leases, and the exchange of school trust lands within the park for other lands.
Natural stone openings are found all over the Colorado Plateau, and in other parts of the world where easily erodable stone weathers into semistable arches. But no place on earth can match Arches National Park for the dense concentration of these strangely graceful formations. Depending on what your criteria are for a measurable arch, there are about 900 stone windows, doorways, and eyes in the park. This trail guide includes descriptions of Lower Courthouse Wash."
