It is a wide shallow basin with outliers of granite ridges and rounded up swith and over by a guesta of Comanchian hills after hundreds feet high. The floor of the basin is paleoaddle schist cut by red crassly crystalline granite and upon which are local occurrences of Devon Cambrian, Cariboo- Ordovician [and] means the anticlinal Comanchian. In places the Paleogries stand steeple but as a rule they lie in undulations but dipping to the N and NW. Lellards [says] the doming of the Mineral Belt took place after the Benal and seemingly went on until some time into the oldu strata. The Pre-Cambrian rocks Page (Foliz) makes Algortian, and Lellards says that some schists only appear to have revealed Radiolaria. Look into this matter to see if they are actually Radiolaria. Saw some granites fedded-like cutting back at an angle of about 70 degrees. The Comanchian laps against the domed Min- eral Belt and finally around it. There is no rim or cuesta around the north side of the Mineral Belt
