Along the trail to Landscape is a short side trail to Pine Tree Arch and Tunnel Arch.
Pine Tree Arch and beyond
Tunnel Arch (actually two arches)
This arch could collapse at any time. On September 1, 1991, a 73-foot slab of rock fell out from underneath the thinnest section of the span, reducing the thickness of the span from 16 feet to 11 feet. On June 5, 1995, a 47-foot mass of rock fell from the front of the thinnest section of the arch, followed by another 30-foot rock fall on June 21, 1995. The short loop trail that went directly underneath the arch has been closed because of government liability should more rock fall. Another arch, Wall Arch did fall recently, in 2008. Prior to its collapse, it was the 12 largest of the park’s more than 2000 arches.
The trail continued on, but the wind was getting strong, and the next stretch would have been over slickrock, where we really have been exposed to the wind, so we called it a day and returned, for a total hike of about 2 miles.
