"more galbros and [illegible] in the point in N.W. 8.21.7" (a problem) by a cent. I found 50 feet (exposed) of black bedded porphyry tuff, successively lower & normally with angular lapillae. A specimen without the lapillae is [no 5]. These tuffs are of a very dark matrix with dark fragments, quite different from the typical and tuffs. They appear to be basic. They are underlain by a washed agglomerate in a mound of dark red color. The strike runs around from N 60 just above the middle of 8.21.7 to N.30 E. at the lower edge. Dip 27-530 E.
