Index No. MRDS090017; Dimension Stone Project; Dark dreenish gray diorite. Geology: Large stock covering about 1.2 km2 with a number of smaller stocks and dikes. Dikes generally strike NNW-NE. Potential: Too fractured and iron stained. Maybe useful for landscaping. Field Notes: No outcrops on lower slopes, but are visible high up on ridge. From distance, these appear highly jointed, and associated scree shows rock fractures into blocks. Blocky boulders in drainage are up to 60 cm by 60 cm. Rocks weather dark grayish brown, and fresh surface is of medium gray with slight greenish tint plag porphyry. Some Fe-oxide clots and staining.
