Snowmass CreekSnowmass Creek is a tributary of the Roaring Fork River in Pitkin County, Colorado.CourseThe creek rises north of the Maroon Bells in the White River National Forest. From there, it travels generally north, losing some of its flow to ditch diversions, and finally passing under State Highway 82 to its confluence with the Roaring Fork River just north of the highway at the community of Snowmass, Colorado.
