2024 Map of Rocky Reef
USGS Topo · Published 2024About this map
The Missouri River winds through the northern reaches of this landscape, flanked by the Tintinger Slough and the level expanse of Antelope Flat. This 2024 survey documents a rugged transition from the river valley to the prominent heights of Harris Mtn and the distinct geologic formation of the Rocky Reef. The presence of the Chestnut Valley Canal illustrates the enduring importance of water management in this part of Cascade County, where irrigation infrastructure snakes across the terrain to support local ranching and agriculture.
