Montana City located five miles south of Helena was once a thriving gold camp located along Great Northern railroad. The lure of the discovery of gold at Last Chance Gulch was the same that attracted miners and prospectors to settle in Montana City. As hopes for fortune declined the once bustling placer mining camp dwindled. Very little remained in the area until again interest in the area was rekindled by its geological makeup, but this time not gold but lime rock and silica. Henry Kaiser felt that the abandoned lime quarry in Montana City was a prime location for a wet process cement plant. Montana City began to redevelop and today is a outlying suburban community of Helena.
