2024 Map of Grand Island
USGS Topo · Published 2024About this map
The Missouri River carves a dramatic path through the high plains of central Montana, serving as the physical boundary between Phillips County and Fergus County. This river corridor is protected within the Charles M. Russell National Wildlife Refuge and the Upper Missouri River Breaks National Monument, preserving a landscape of braided channels and river islands. Notable landforms such as Grand Island, Upper Two Calf Island, and Lower Two Calf Island sit within the Missouri Wild and Scenic River designation. On the southern banks, the terrain rises into Barnes Ridge and the low-lying Kendall Bottoms. Sparse human infrastructure is limited to the Heller Farm Airport and Knox Ridge Road, while the surrounding geography is defined by deep drainages like Hideaways Coulee and Two Calf Creek.
