House Range


The House Range is a north-south trending mountain range in Millard County, of west-central Utah. The House Range was named in 1859 by James H. Simpson. It was named by Simpson because "...of its well-defined stratification and the resemblance of portions of its outline to domes, minarets, houses, and other structures."

Geography

The House Range is bounded by Tule Valley to the west, Whirlwind Valley and Sevier Desert to the east, and trends with the Fish Springs Range to the north. The range has three notable passes: Skull Rock Pass, Marjum Canyon, and Sand Pass.
The highest point in the House Range is Swasey Peak, at. Other notable peaks include Notch Peak, a frequent climbing and base-jumping hotspot, and the very square Tatow Knob.
It is also known for one of the tallest limestone cliffs in the world, Notch Peak.

Geology

The geology of the House Range is dominated by gray Cambrian to Devonian carbonate rock which was intruded by a pink Jurassic granitoid in the central part of the range. In the Wheeler Amphitheater, away from the intrusion, the Lagerstätte that contains the well-preserved fauna is found in the Cambrian section of the range. Evidence of Lake Bonneville's presence is found both in shorelines and white marls at the base of the range. The main structural component to the range is a large basin-bounding fault on the west side.

Fossils

The range is known for a fossil Lagerstätte of Cambrian age, which has an array of Burgess Shale type fauna, including Elrathia kingii, a trilobite that is one of Utah's most famous fossils.

Stratigraphy

The Swasey Limestone was deposited in the Bathyuriscus-Elrathina zone. This is overlain in turn by the Bolaspidella zone Wheeler Shale and Marjum Formation, then the Cedaria zone Weeks Formation.
