Many of the stories collected by Clark deal with landscape features of specific regions of North America. These and other stories contain indigenous knowledge about landmarks as, for example, Crater Lake and cataclysmic events such as earthquakes and floods, and have been used to gain additional insights into the geological past.see e.g.: Piccardi, L., and W. B. Masse, eds. Myth and Geology. London: Geological Society, 2007. Ludwin, R. S., et al. “Dating the 1700 Cascadia Earthquake: Great Coastal Earthquakes in Native Stories.” Seismological Research Letters 76.2 (2005): 140–48.
