This pair of photos shows two views of a scene that no longer exists. The Copper Mountain patrol cabin, built in 1928, is pictured. Note that the Thorofare River migrated over to the cabin in the period between the two photos, and that by 1958 it was flowing very close to the cabin. This event was ultimately the undoing of this patrol cabin, because the huge amounts of sediment transported by the river eventually buried this cabin entirely in boulders, cobbles and gravel. In fact, by 2010 there was no trace left of the cabin seen in these photos! To see more dramatic evidence of this geologic process, type "Copper+Mountain+Cabin" into the Search photo pairs box.
