Granger sandstone (of Kosanke and others, 1960), or Curlew sandstone of earlier reports, here informally called golden sandstone. According to authors this unit was miscorrelated by previous workers and is not equivalent to the type Granger or Curlew. The name used in this report refers to the color of the rock on some weathered surfaces.
