40 Alt San Joaq [Joaquin] Cascades 650 ft Alt bot [bottom] 8950

The river forks here the left valley is deeper & every way larger but far greater portion of water comes from right cascades here in vert [vertical] leaps but short comes from fine vall [valley] with out [ ] in background to val [valley] at fork. Whole descent about 700 ft. This is very interesting place from the meeting of granite with the slate. Slate op S 20[W] granite N a little higher [sketch of a valley: “s” “g”] the rock is planed smooth with

41 ice showing splendid sections with all kinds of granite veins & map shaped & boulder shaped masses of every size in the dark slate. Mostly the granite & slate however mixed yet are seperate [separate] & meet sharply but in some places they seem to blend, but in all cases every crack & seam & joint belonging to one is contoured on through the other. Granite has the same physical structure essentially as slate. This true on grand or small scale.
