Plans for the Original Bonanza Ore Bunker:
These were the plans for the ore bunker you see here. Although the roofline was significantly altered, the plans you see are otherwise the bunker and tram terminal as it was at abandonment.

Later on that area was covered with an extensive snow shed. Click either plan for a larger version.
Note the severe steepness of the terrain that even shows up in the 1911 plans.
