"Rapids and Cascade"
This stretch of rapids and pitches is nearly three miles above Grand Falls, and a little over one mile below Crooked Falls. It could be the "Rapids and cascade of about 10 feet descent" that Clark indicated on his map of the falls, below the "Deep Ravine."
On June fifteenth, 1805, Lewis had noted the significance of the ravines seen in this photo.
The ravines downstream near the Grand Falls are even deeper and longer than these.
At left, on the horizon, is the smokestack built in 1908 by the Anaconda Copper Mining Company to vent sulfurous fumes from the smelter built at Black Eagle Falls in the early 1890s. It was demolished in 1938.
