The high-country terrain west of Boulder is defined by a dense network of drainages and ridges within the Deerlodge National Forest. Significant elevation changes are marked by landmarks such as Mt Pisgah and Pulpit Rock, while the southern portion of the map is dominated by the complex watershed of the Little Boulder River. This 2017 survey details the transition from the town of Boulder in the northeast into the more primitive landscape of the forest, where numerous gulches like Galena Gulch and Porcupine Gulch speak to the area's prospecting and ranching history.
