When you are tired of stream bed gravel you are tired of life.
Butte Montana from the Montana Tech campus hill. The old Berkley Pit and new open pit copper mine are visible just below the mountains. The two pits are over two kilometers long. You can see the white Our Lady of the Rockies statue on the crest of the mountains. The statue is about twenty-five meters high. Butte has lost population from its copper glory days but remains a scenic small western city.
