Notch Peak
A huge limestone cliff in the House Range of the west desert, with ancient bristlecone pines.
Notch Peak rises in the House Range of western Millard County. The Utah Geological Survey gives 9,654 feet. The Bureau of Land Management says the name comes from a notch near the top of its western cliff, and the surrounding Notch Peak Wilderness Study Area is run from BLM's Fillmore Field Office.
The upper mountain is limestone and dolomite laid down about 500 million years ago, above much younger Jurassic granite. The survey measures a near-vertical drop of more than 1,500 feet on the west face, and notes that larger figures depend on how much slope below is counted. BLM documents bristlecone pines on the high ridges more than 2,000 years old.
