Wall Arch was a natural sandstone arch in the Arches National Park in the U.S. state of Utah. Before its collapse in 2008, it was ranked 12th in size among the park's over 2,000 arches. At its largest, the opening underneath the span was 71 feet (22 m) wide by 33.5 feet (10 m) high. It consisted of Entrada Sandstone, specifically the member known as Slick Rock. Wall Arch was first reported and named in 1948 by Lewis T. McKinney.
Wall Arch collapsed sometime between the night of August 4, 2008, and the morning of August 5, temporarily blocking Devil's Garden Trail. No one observed the fall. It was the first collapse of a major arch in the park since sections of Landscape Arch fell in 1991. Officials from the National Park Service and Utah Geological Survey visited the site of the collapsed sandstone arch on Thursday, August 7, and noted stress fractures in the remaining formation which may cause collapses in the future.
Famous quotes containing the words arch and/or wall:
“Prayer is the fair and radiant daughter of all the human virtues, the arch connecting heaven and earth, the sweet companion that is alike the lion and the dove; and prayer will give you the key of heaven. As pure and as bold as innocence, as strong as all things are that are entire and single, this fair and invincible queen rests on the material world; she has taken possession of it; for, like the sun, she casts about it a sphere of light.”
—Honoré De Balzac (17991850)
“The mountain stood there to be pointed at.
Pasture ran up the side a little way,
And then there was a wall of trees with trunks;
After that only tops of trees, and cliffs
Imperfectly concealed among the leaves.”
—Robert Frost (18741963)
