Summary Author: Ryan Moreau
Shown above is the so called Lace Curtain that stands on the north slope of a long-extinct volcano of Pahvant Butte, in central Utah. This cliff remnant was created when volcanic tuff from a subaqueous eruption approximately 15,500 years ago was loosely cemented by minerals found in ancient Lake Bonneville. The cliff face was partially submerged in this lake. The outer portion of the cliff was hardened while the interior was left much softer. In addition, erosion by storm waves on the lake and by wind after the lake dried up helped shape the formation seen today. Photo taken on February 16, 2015.
