This report was undertaken primarily as a study of Pennsylvanian strata which crop out in the Sedillo-Cedro Canyon area. The subdivision of the Madera formation as proposed by Read and others (1944) was adopted for purposes of mapping. This subdivision is based on a dominance of either limestone or clastic rocks in the formation.
The writer was unable to measure a Pennsylvanian section in the field due to thickness changes, facies gradations, and faults which were often concealed by dense soil cover. However, by visually traversing the area on aerial photographs using arbitrarily chosen zones, estimated thicknesses for the members were obtained. These thicknesses used in conjunction with studies of topographic maps and field observations enabled the writer to prepare a geologic map showing structural relief within the area.
