Comments on the geologic information

  • Geologic Description = The U.S. Bureau of Mines (1973) reported nine lode claims at this locality, which is the only indication of mineral resources. Nelson and others (1983, unit KJs) described the bedrock in the area as interbedded lithic graywacke, silty sandstone, black shale , and local conglomerate. Irregular quartz segregations and veinlets are locally present. Scattered stocks and locally abundant dikes of intermediate to felsic composition intrude these sedimentary rocks. Adjacent to some of the larger igneous bodies are narrow contact aureoles of pelitic hornfels.?
  • Age = Post Cretaceous to Jurassic
