NOAA Photo Library Image - cgs05230

Tertiary Triangulation of Half Moon Bay, California by the party of A. F. Rodgers, Assistant U.S. Coast Survey. G. Farquhar Observer. Note Rodgers signature. Unfortunately, his hand-writing is nearly indecipherable as he spent fifty years on the West Coast and wrote many reports of his activities in a near pioneer environment.
