Glen Canyon National Recreation Area

The Glen Canyon National Recreation Area (Glen Canyon NRA,GCNRA) was established in 1972  to provide for public use and enjoyment and to preserve the area's scientific, historic, and scenic features.  Glen Canyon NRA occupies 1,959.6 mi² (5,075.3 km²) with the major attractions of Lake Powell and Rainbow Bridge (2.3 million and 100,000 visitors annually).  Lake Powell is a reservoir on the Colorado River, created by the flooding of Glen Canyon by the Glen Canyon Dam (which led to the creation of Glen Canyon NRA).  It is the second largest man-made reservoir by capacity in the United States behind Lake Mead.  The reservoir is named for explorer John Wesley Powell, a one-armed American Civil War veteran who explored the river via three wooden boats in 1869.  Rainbow Bridge National Monument, a separate unit inside of and managed by Glen Canyon NRA, and the Horseshoe Bend viewpoint inside Glen Canyon NRA 5 miles (8 km) south of the dam, have separate articles with their stories and photos.

Lake Powell is a gangling lake with long arms extending up canyons and tributaries on both sides along the 186-mile channel of the Colorado River in majestic Glen Canyon, with a shoreline exceeding 2,000 miles - longer than the entire west coast of the US.  The lake twists and turns, with river arms and canyons 15 to 20 miles in length - there are 96 major canyons off Lake Powell.  Five marinas and a number of primitive launch points provide boating access to Lake Powell.  Hite Marina and most primitive ramps are currently closed by an extended drought  (see Colorado Basin Drought).  Many of the photos show the depth of the drought with bathtub rings from calcium carbonate and other hard minerals in the water that attach themselves to the darker-colored sandstone.  There has been some relief this water year (2016-2017), but the lake is still running 71 feet (21.8 meters) below full pool.

The photo Gallery includes scenic photos inside Glen Canyon NRA including photos from contests, Rainbow Bridge, and Horseshoe Bend.
