Grouped in threes for the music. Parenthesized (in source) information about counties (Los Angeles or Orange), previous surveys (surveyor and date), and most notes, have been removed, but can be found in source. The earlier surveys — A. W. Chase, 1872-73; W. E. Greenwell, 1863; A. F. Rodgers, 1883; and F. Westdahl, 1899 — are discussed at 528ff.
Asterisks stand for benchmark symbols.
from A. L. Baldwin his introductory General Statement —
“Miss Lilian Pike, assisted by Mr. C. R. Duvall, made the least square adjustments of the primary work; and Miss Pike also directed the preparation of the descriptions.” p 495
—
Some of the station names ring faint personal bells (Point Fermin, Drum); others (all, really) are otherwise evocative (Curve, Knob, Mustard, Solitary, Spring, Unknown). Miss Pike’s beautiful descriptions speak for themselves.
Had been searching Rattlesnake [now Terminal] Island. Fixing locations, in uncertain ground.
