Examining the development of soil is a reliable method for evaluating the age of geological features. As rocks weather and erode, soil begins to form on top of them. By analyzing the type and depth of soil present, geologists can make inferences about the age of the underlying rock. This is likely the method used by the USGS to evaluate the age of different parts of the Slumgullion feature.
