2024 Map of Hole-in-the-Rock

About this map

Hole-in-the-Rock serves as the central landmark for this stretch of the central Montana rangelands, where the high plains break into a complex system of drainages. The landscape is defined by the carved paths of Big Porcupine Creek and Indian Creek, which cut through the underlying geology to form deep, named depressions like Devils Canyon. The boundary between Garfield and Rosebud counties runs across the northern portion of the sheet, marking a transition in local administration within this sparsely populated grazing country.
