About this map

Hillsboro sits within a complex geological landscape at the edge of the Bighorn Canyon National Recreation Area, where the Bighorn River carves through deep drainages along the Big Horn and Carbon county line. The map illustrates a high-desert terrain defined by named depressions and canyon systems, including Wassin Canyon, Chain Canyon, and the prominent Garvin Basin. Transport in this part of Montana is dictated by the rugged topography, with Dryhead Road and Hillsboro Road providing access to the area's natural landmarks.

To the south, the landscape becomes increasingly dramatic as the river enters Devil Canyon near the Natural Corrals. This 2024 survey detail is particularly valuable for understanding the modern boundary management of public lands and the preserved hydrological features like Barrys Island and Porcupine Creek. The intricate contouring reveals the steep elevation changes that characterize the transition from open basins to the sheer canyon walls of the Bighorn system.
