05-11-21 – Hole-in-the-Rock


Hole in the Rock is a narrow and steep crevice in the western rim of Glen Canyon, in southern Utah in the western United States. Together with another canyon on the eastern side of the Colorado River, it provided a route through what would otherwise be a large area of impassable terrain.

In the fall of 1879, the San Juan Expedition of the Church of Jesus Christ of Latter-day Saints was seeking a route from south-central Utah to their proposed colony in the far southeastern corner of the state. Rejecting two longer routes, they chose a more direct path that initially took them along the relatively benign terrain beneath the Straight Cliffs of the Kaiparowits Plateau. However, when this led them to the 1200-foot (400 m) sandstone cliffs that surround Glen Canyon, they needed a way to cross to the eastern rim. They found (and named) Hole in the Rock, a narrow, steep, and rocky crevice and sandy slope that led down to the river. Directly across the river was Cottonwood Canyon, a tempting route up to Wilson Mesa on the other side.

They worked for months to prepare the road, using blasting powder to widen the upper section and hand chisels to carve anchor points directly into the sandstone. On January 26, 1880 the expedition (250 people, 83 full-sized wagons, and over 1000 head of livestock) began their descent to the river. Wagons were heavily roped, and teams of men and oxen used to lower them through the upper crevice, which has slopes approaching 45°. Further down, a wooden track had been constructed along a slickrock sandstone slope. Posts in drilled holes supported horizontal beams to allow passage of the wagons.

After an even more difficult journey on the east side of the river, the expedition founded the community of Bluff in southeastern Utah. They used the Hole in the Rock route as a supply road for only a year before replacing it with an easier route to the north, at Hall’s Crossing. Decades later, miners of the Hoskaninni Mining Company carved steps onto the same path used by the Mormon pioneers. The blasting holes, anchor points, and gouges from the hubs of the expedition’s wagons are still visible in the walls of the crevice.

12-01-19 – Glen Canyon National Recreation Area

Glen Canyon National Recreation Area (shortened to Glen Canyon NRA or GCNRA) is a recreation and conservation unit of the United States National Park Service that encompasses the area around Lake Powell and lower Cataract Canyon in Utah and Arizona, covering 1,254,429 acres (5,076.49 km2) of mostly rugged high desert terrain. The recreation area is named for Glen Canyon, which was flooded by the Glen Canyon Dam, completed in 1966, and is now mostly submerged beneath the waters of Lake Powell.

Glen Canyon NRA borders Capitol Reef National Park and Canyonlands National Park on the north, Grand Staircase-Escalante National Monument on the west, Vermilion Cliffs National Monument and the northeasternmost reaches of Grand Canyon National Park on the southwest, and the Navajo Nation on the southeast. The southwestern end of Glen Canyon NRA in Arizona can be accessed via U.S. Route 89 and State Route 98. State Route 95 and State Route 276 lead to the northeastern end of the recreation area in Utah.

Glen Canyon NRA was established in 1972 “to provide for public use and enjoyment and to preserve the area’s scientific, historic, and scenic features.” The stated purpose of Glen Canyon NRA is for recreation as well as preservation (whereas a national park may carry more emphasis on natural preservation). As such, the area has been developed for access to Lake Powell via five marinas, four public campgrounds, two small airports, and numerous houseboat rental concessions.

The geology of the area is dominated by the Glen Canyon Group, consisting of the Navajo Sandstone, Kayenta Formation, and Wingate Sandstone. The entire stratigraphic section includes rocks dating from the Cretaceous to Pennsylvanian periods.
