|May 2006 (38.272 Degrees, -109.371 Degrees) Wilson Arch|
The sandstone is gradually eroded by wind and flowing water. The expansion of ice crystals crack the rock and blowing winds remove particles until jagged fins remain. More erosion cuts a hole through the fins, which vary from tens to hundreds of feet in length.
Wilson Arch is 91 ft long and 46 ft high. It was named after Joe Wilson, who was a pioneer who lived nearby. Although Wilson Arch probably gets less foot traffic than most bridges in the area, natural arches may have been some of the first footbridges and possibly inspired the first human-made arch bridges.
