Mt. Glory sits on top of Teton Pass, which has been a very important corridor for travel for 10,000 years. The pass is a windy, connecting road between Wyoming and Idaho that allows people to travel through the mountains vs. taking the long road around. The pass peaks at 8,431 ft of elevation, and often deals with large avalanches that can cover and close the entire road for hours even days.
Rock quarries in the pass used to make it very valuable for obsidian mining to make tools in the late 1800s. First settlers and mountain men would travel by Wagon over the pass, taking weeks to get family and livestock across. In 1928 the official old pass road was built, and in 1969 the newer (now used) road was built.
Mt. Glory is a mountain right off the side of the pass, and starting in the early 1900s people began to ski the pass and this mountain as the terrain was phenomenal for skiing and very accessible compared to other mountains in the valley.
