Frenchman Mountain is located east of Las Vegas, Nevada, United States. It is not part of any mountain range. Comprised of rocks similar to those found on the bottom of the Grand Canyon, Frenchman Mountain formed when faulting elevated it, giving it its sharp triangulated slope. It is the site of the Great Unconformity. It is underlain by Vishnu Schist rock, which is some of the oldest rock on the North American continent, having been created about two billion years ago.
State Route 147 crosses its northern slope. A geologically rich area called Rainbow Gardens is located to its southeast, as is an igneous laccolith, Lava Butte. [4]
It is commonly, and mistakenly, referred to as Sunrise Mountain, the name of a smaller peak to the north of Frenchman Mountain. The area from Cheyenne Avenue and Boulder Highway and Lamb Boulevard is commonly known as Sunrise Manor Township CDP.
