Mount Pennell
History
This mountain was first called Un-chu'-ka-ret by the native Paiute.
Almon Harris Thompson served as chief topographer and geographer of John Wesley Powell's Second Geographical Expedition (1871–1875) when he named Mount Ellen after his wife, Ellen Powell Thompson, and Mount Pennell was later named for his friend Joseph Pennell (1857–1926), an American artist and author.
The American geologist Grove Karl Gilbert surveyed this area in 1875 and 1876, and published his findings in 1879 as a monograph, The Geology of the Henry Mountains. The term laccolith was first applied as laccolite by Gilbert after his study of intrusions of diorite in the Henry Mountains.

Spring and fall are the most favorable seasons to visit Mount Pennell. According to the Köppen climate classification system, it is located in a cold semi-arid climate zone, which is defined by the coldest month having an average mean temperature below 32 °F (0 °C), and at least 50% of the total annual precipitation being received during the spring and summer. This desert climate receives less than 10 inches (250 millimeters) of annual rainfall, and snowfall is generally light during the winter.
