Devil's Backbone - Crater Lake National Park - Crater Lake, OR - Geological Devilish Locations on Waymarking.com

"Devil's Backbone is a vertical wall of dark, volcanic rock called andesite. It lines the cliff face and measures at 304 meters long by 50 meters wide at the top. The technical term of a rock formation similar to Devil's Backbone is a dike. All dikes are formed by molten lava which overpowers and fills a type of crevice, then builds up over time to create the slanted, sleek formation you see in Devil's Backbone. As the only dike to reach from the water's edge to the rim, Devil's backbone is a geologic fascination to remain intact despite the persistent erosion process. Wind, snow, or rain can weather or break apart rock on Devil's Backbone, then, it will erode or move down the slanted hillside. Finally, the weathered and eroded rock goes through deposition as it settles or deposits at the bottom of the hillside, or into the lake. Not only is Devil's Backbone an interesting geologic site, it is the only dike which has rock at the bottom of the bank and the top of the rim which have not eroded away." (visit link)
