About this map

Bitterroot National Forest lands dominate this late-1990s landscape, illustrating the complex intersection of federal conservation and valley irrigation in Ravalli County. The western edge of the map shows the outskirts of Hamilton, featuring the Hamilton Airport and Hamilton Golf Course, along with a state-managed Fish Hatchery. A sophisticated network of water management is visible, including the Hedge Ditch, Ward Ditch, and the extensive Bitterroot Irrigation District Canal, which feed the agricultural bottomlands from the higher peaks.

The topography transitions sharply into the Sapphire Mountains, marked by the eponymous Mountain House and Mountain House Spring. Numerous drainages such as Skalkaho Creek and Sleeping Child Creek carve deep through the terrain, with several gravel pits and a Quarry indicating local extraction. The boundary for the Darby Ranger District outlines the managed forest areas, providing a detailed record of land use before the turn of the century.
