About this map

Chilly sits at the eastern edge of a high-altitude basin where the Thousand Springs Valley meets the lower slopes of the White Knob Mountains. This 2023 edition documents a landscape defined by water management and topography, where the Big Lost River and its tributaries like Grant Creek and Talman Creek are essential to the agrarian footprint on Barton Flats. The presence of the Chilly Canal illustrates the long-standing reliance on irrigation to support life and industry in this part of Custer County.

Local history is anchored by landmarks such as the Chilly Cem, situated near the prominent Chilly Buttes. The mapping of small roads and ways, including Walker Way and Circle Rig Way, provides a contemporary view of access and settlement patterns. From the elevations of Swensen Butte to the drainages of Rock Creek, the map details a region where natural features and human infrastructure remain closely intertwined.
