Helena National Forest and Deerlodge National Forest meet in this Powell County terrain, where an intricate network of waterways defines the mountain geography. The drainage patterns of the Spotted Dog Creek system, including the Elliston Spotted Dog Creek and several forks, illustrate the complex hydrology of the Continental Divide region. To the south, Baggs Creek and Rocker Gulch feed into the North Fork Cottonwood Creek basin.
