Divide derives its name from it's proximity to the Continental Divide; where waters on the west side flow towards the Pacific Ocean and waters on the east side flow towards the Gulf of Mexico. As a station on the Union Pacific, Divide served as a distribution and stock shipping point for the Big Hole Valley. (from Cheney's
Names on the Face of Montana, Mountain Press Publishing Company)
The Big Hole River Special Management Area extends approximately 35 miles upstream and 38 miles downstream from Divide. The Big Hole River, a blue ribbon trout stream, provides excellent fishing and floating opportunities with a number of access points being available from State Highway 43 and Interstate Highway 15. Overnight camping and boat launch facilities are provided at BLM-managed sites at Divide Bridge,
Dickie Bridge, and
East Bank, all located between Divide and Wisdom, Montana. Day use facilities and a boat launch are available at the
Jerry Creek Bridge Site.
