.. .In my mother's words..."Castner Falls lay between Deep Creek on the east and the Missouri River on the west. Castner Coulee is about seven miles in length and is believed to be a fault caused by an earthquake. There are places along the sides, which are steep and high. At other locations it is possible to walk or drive into it without difficulty. Before 1900 there were two houses built in the coulee and abandoned. There was also a school house located there. The creek which falls over and through the coulee is not a large one. It is believed that Castner Falls was named for John Castner, a pioneer cattleman.

Cascade is on the western side of the Missouri River, Castner Falls and many other settlements, on the eastern side.
