The Marshall Valley Trail is closed due to a mine cave-in approximately 100 yards east of the trailhead. The Marshall Valley trail is the lower traverse heading east from the trailhead to where it connects with the community ditch at the bridge. The Marshall Mesa trail system sits on top of several old coal mines. Users of the area should always be cautious due to the potential for mine cave-ins at any time. State Mine Safety staff has been notified and will be coordinating mitigation starting on Monday.
Users are highly encouraged to respect the closure for their own safety.
At this time, Coal Seam and Community Ditch trails may be still accessible for mountain biking, hiking and trail running.
