Wood dam in a postfire debris-flow deposit within in the 2024 Elk Fire burn area

Postfire debris-flow deposit in the 2024 Elk Fire burn area near Dayton, Wyoming. A debris flow triggered by a July 2025 thunderstorm deposited sediment and woody debris within the channel. Downed trees, oriented perpendicular to the channel banks, form a wood dam. The trees were carried by the debris flow, and some have been stripped of their bark by the force of the flow.
