The butte, sometimes called "Sugarloaf Mountain" by locals, is located in the Sevier Desert in the Pahvant Valley 15.7 miles (25.3 km) south of Delta and five miles east of Clear Lake and the Clear Lake Wildlife Management Area. Originally a subaqueous volcano, it erupted out of the floor of Lake Bonneville approximately 15,500 years ago. Along the southeast rim of the inner depression of the volcano is an unfinished structure consisting of a concrete building embedded in the hill surrounded by two rings of concrete obelisks. A man named A. H. Hood, created these structures with the intention of generating wind power, in 1923. He only got as far as creating the base and the generator house which remain today. The Lace Curtain is a natural phenomenon located at the north base of the butte. The cliff is known as the "Lace Curtain" because of its white color and mysterious lacey pattern. During the volcano eruption storm waves and wind cooled the lava as it flowed from the volcano and formed this unique rock pattern seen today. Cell phone service is intermittent. The nearest services are in Delta or Fillmore.
