Ran full path passing under the Highway 2 Goat Lick bridge. Approximately 20 m of debris remained in the path under the Goat Lick bridge. Debris terminus temporarily blocked the Middle Fork of the Flathead River and was approximately 30 m in height. Caused by significant precipitation intensities, heavy snowfall rates, and air temperatures near freezing.
