The Missouri Mine is located just above the timber line near the head of Hall Valley. The site is on the opposite (eastern) side of the Continental Divide from the main part of the Montezuma District but is treated under Montezuma by Lovering and Goddard (1950), the principal descriptive source. This mine is known for bismuth minerals. In 1973 spots in the dump containing fragments of the bismuth-bearing ore were marked by splotches of yellow “bismuth ocher”.
Due to the altitude the climate at this locality is severe. In late June 1973 substantial unmelted snow drifts were still present. Around a beaver pond just below the mine pussy willow was just coming out. A black cloud suddenly appeared, there was an icy wind and a hard, 5 minute snow squall.
