Dyke C This dyke is similar to c in that it seems to be a lateral dyke. It is broken off breadth at lower part or same height with base of and about 2i feet vertical east of " At lower part this dyke is about" thick but gets thicker higher up in the cliff while it reaches a thickness of about 40" Below is a sketch of dykes as they appear in the vertical cliff. Vertical distance 35' Horizontal distance 12' Genoa? L (La Patagia?) In second branch on east side of Salmon creek at 650 elevation are al number of small dykes. Their general direction is N.40Wd S.60E. Dyke A This is a small dyke the pointed west edge of which on south side starts from 80' and reaches to the base " in the " exposure beyond which it is ground " B This dyke starts from about 1' east of 9" and about 30' south. starting at A. Extends N. under the water of stream reaching a little on and back on this form. " L This dyke at west edge is 3" thick is 15' east of B and breaks off under middle of stream but extends 5' and goes under covered. ( A ) This dyke is 5" thick and extends to middle of stream and then the corner to southly stream about 10' exposure. It is 5 1/2' east of L. " C This dyke is 6" wide with a 3/4" shale band dividing it in middle the oh horizon forming one edge of water but starts to S. A 15' from north N. is good exposure and is 3 1/2' east of A. North of B in middle of stream. " D This is a thin dyke the thick part on west edge) 7/8' and peaks out in either direction to S. end making an all about a 7 exposure, Mid4' 4" east of C. " G As a very thin one 1/2' thick at Sand I found it ran up to 3 feet within 7'. " H Is a little one beyond A 1' long & Thick exposure as I could not tag it. Located from g below.
