Summary

With an impressive elevation of 12,605 feet (3,842 meters), it stands as one of the highest peaks in the Teton Range. This majestic mountain boasts a significant size, with a vertical rise of over 5,000 feet (1,524 meters) from nearby Jackson Lake.

During the winter season, Mount Moran receives substantial snowfall, contributing to its reputation as a challenging destination for mountaineers. The snowpack range varies depending on the year and weather conditions, typically averaging between 150-200 inches (381-508 cm) of snow accumulation. This deep snowpack poses additional difficulties and risks for climbers, requiring specialized equipment and expertise to navigate the mountain safely.

Mount Moran's snowmelt feeds into several creeks and rivers in the surrounding area. One notable example is the beautiful Leigh Lake, located on the eastern side of the mountain. This lake receives runoff from glaciers and snowfields on Mount Moran, highlighting the interconnectedness of the mountain and its surrounding ecosystem.

The name "Moran" was given to the mountain in honor of Thomas Moran, a renowned American painter from the 19th century. Thomas Moran was part of the Hayden Geological Survey of 1871, which extensively explored and documented the Yellowstone region. His stunning landscape paintings played a crucial role in convincing Congress to establish Yellowstone as the first national park in the United States in 1872.

While Mount Moran may lack specific legends or folklore, its rich history and challenging nature make it a significant destination for mountaineers and nature enthusiasts alike.
