This small pond at the bottom of a forested bluff is on Clark County’s East Fork Lewis River Greenway property. A heron or egret may be poised by the water’s edge. Native aquatic plants such as bulrush, bur-reed, bladderwort, and wapato or arrowleaf live here. Beyond a bridge at the pond, there’s a sign welcoming the public to the greenway.
