Union Peak is a heavily eroded
glacial horn. This is the same process that formed the summit horns of Three Fingered Jack, Mount Washington, Howlock Mountain, and Mount Thielsen
from other shield volcanoes farther north in the Oregon Cascades.
Union Peak is located within Crater Lake National Park,[3] and the summit was used as a post for fire lookouts from the 1930s to the 1950s. A 5.5-mile (8.9 km) trail leads to the summit from the Pacific Crest Trail off Oregon Route 62.
