on the trail

This unique hike passes by the location of a now extinguished gas flame, caused by prospectors in 1911 drilling for coal opening up  a pocket of natural gas that began burning, and a geyser of water in a stream that is still bubbling. It combines walking along the river with hiking over a hill and having lunch at a picnic table.  There is a variety of colorful scenery along the trail.
