Hell Roaring Creek, Stream in Beaverhead County, Montana, United States.

Hell Roaring Creek is a mountain stream in Beaverhead County, in southern Montana, that flows through a remote and largely undeveloped landscape before reaching the Red Rock River. It originates at Brower's Spring, a source recognized as the farthest headwater of the entire Missouri River system.

The creek gained attention in the early 19th century when explorers pushing into the American West began mapping the upper reaches of the Missouri River system. Its source at Brower's Spring was eventually identified as the most distant point of that vast river network.

The creek's name was given by early settlers who passed through this remote corner of Montana and wanted to capture the rough sound the water makes as it tumbles through the terrain. Today, anyone standing near the banks can immediately understand why that name stuck.

The creek sits in a remote high-elevation area reached by roads through Beaverhead County, so conditions can change quickly depending on the season. Visitors should come prepared for rough terrain and limited facilities, as the surrounding land is largely undeveloped.

A short ethnographic film made in 2010 recorded a shepherdess crossing the water with her flock at dawn, capturing a working practice that has changed little over generations. The footage shows how herders still move through this land the same way people did long before maps were drawn of it.
