Gravel bars along the Washougal River yield moss agate, carnelian, jasper, and petrified wood weathered from the surrounding volcanic terrain. The best collecting follows high water, when receding flows expose fresh gravel along the bars. The only documented amethyst in the area is a small amount of amethystine quartz on a mine dump upriver in Skamania County, not the Clark County riverbank.
