Union Peak is a prominent summit located in the Pacific Ranges mountain range, known for its impressive elevation and size. Standing tall at an elevation of 2,421 meters (7,943 feet), it offers breathtaking views of the surrounding landscapes. This majestic peak is a popular destination for mountaineers and outdoor enthusiasts, attracting adventurers from around the world.

During the winter season, Union Peak receives a substantial amount of snowfall, resulting in a significant snowpack range. The snowpack typically varies depending on the specific year and prevailing weather conditions but can reach depths of several meters. This makes it an ideal location for winter mountaineering and skiing, with various slopes and routes catering to different skill levels.

Union Peak's melting snow contributes to the formation of several creeks and rivers in the region. These waterways benefit from the mountain's runoff, ensuring a steady flow throughout the year. Some notable creeks that receive runoff from Union Peak include Swiftwater Creek, Union Creek, and Fish Creek. These water sources not only provide hydration for wildlife but also offer pristine hiking and fishing opportunities.

The origin of the name "Union Peak" is not well-documented, and it appears that there is no specific history or legend associated with the name. It is likely that the name was given in relation to the mountain's location within the Union Creek watershed or as a tribute to the concept of unity. While the history surrounding the name may be ambiguous, the allure of Union Peak lies in its awe-inspiring elevation, vast snowpack, and the tranquil beauty of the surrounding creeks and rivers.
