The Notch Peak Formation is a geologic formation in Utah. It preserves fossils dating back to the Cambrian period.
The Notch Peak Formation has three recognized members: Hellnmaria, Red Tops, and Lava Dam Members (in ascending order), all of which are composed of limestone and dolomite.[2] It is named after the prominent peak of the same name in the House Range of Utah's West Desert, which is its type locality.[1]
