caption_attribution_description: English: Notch Peak, the most prominent feature in the House Range, Utah. Since the definition of 'cliff' varies, depending on the source, this is the tallest carbonate rock cliff in North America and/or the second tallest pure vertical drop in the United States. Along with the cliff and Sawtooth Canyon below it, you can also see the layered Cambrian to Ordovician passive margin sequence, the pink Notch Peak Monzonite, and the white Lake Bonneville marls.
context_page_description: Notch Peak is a distinctive summit located on Sawtooth Mountain in the House Range, west of Delta, Utah, United States. The peak and the surrounding area are part of the Notch Peak Wilderness Study Area. Bristlecone pines, estimated to be 3,000 to 4,000 years old, are located on the ridges surrounding Notch Peak.
context_section_description: This part of the House Range is chiefly made up of a passive margin sequence of Cambrian to Ordovician carbonate rocks.  The top of the range is the type section for the aptly named Notch Peak Dolomite.  At the base of the range is the pink/orange Notch Peak granite and monzonite, which is Jurassic in age (143 to 169 million years old).  Around Notch Peak, especially from the west side (Tule Valley side), white Lake Bonneville fossiliferous marls occur.
  Because of the intrusion, a hike up the canyon below the notch can clearly show a well-developed metamorphic aureole and even inter-fingering textures between the intrusion and the bedrock.  Also, small quantities of tungsten and placer gold have been found around the Notch Peak area.
