Trail Overview

Pahvant Butte Loop is a 30.3-mile point-to-point trail rated 4 of 10 located in Millard County, Utah. The Pahvant Butte Loop is a destination trail which takes circles the Pahvant Butte an extinct volcano which has several unique sites. Pahvant Butte is can be seen west of I-15 to those driving either north or south on the interstate. With a volcanic history, Pahvant Butte is an interesting landform worthy of exploring. The road leading to Pahvant Butte is a well graded dirt road which leads past the Crystal Lake Waterfowl Management Area. As you approach the dome the road turns to a single dirt road which is passible in a high clearance vehicle, weather permitting. 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.

I ran a partial loop, from Pahvant Butte towards Delta. Most of the trail was in good passable condition. However the bridge over the canal towards the northwest end of the loop is out. We were able to follow the canal service road on the east side of the canal, for about 2 miles to a farm crossing, then on the west & north side service roads up to 4500 S.
