the (unique) station names, Newport Bay to Point Dume, pp 666-671 (omitting all but a few of their respective descriptions).
Sand Hill 3
On the sand hill east of a lagoon. The dune is shifting, and it is not probable that the marks on the station are permanent.
- High Table
About 200 meters from the beach, on a hill a little to the east of the third conspicuous point from a black bluff point down the coast from Point Dume, about three-fourths of a mile west of a lagoon, near which there is a ranch. The station mark was a drill hole in a fixed rock. The reference marks were two drill holes in fixed rocks, one bearing about southwest, distant 10 feet 3 inches, and the other bearing southeast, distant 12 feet.
About 400 meters from the shore, and about 900 meters east of the house on the Rancho del Malaga; on the top of a peak covered with rotten slate which outcrops toward the eastward; a deep gulch runs up toward the west and a smaller one to the east; to the north is a deep basin covered with underbrush of every kind. The station was marked by a drill hole in a fixed rock.
About 15 feet south of the fence inclosing Drum Barracks, and 30 feet east of the road from Wilmington.
- Point Fermin
- R. R. Flagstaff
On the top of the bluff at Timms Point, about 25 feet from the extreme end. A bottle was placed 12 inches below the surface and a piece of scantling over it, the top of which is level with the ground.
On the next prominent point south from Timm’s Point, about 30 feet from either edge of the bluff. A bottle was buried 15 inches below the surface of the ground, and the theodolite stubs were left.
- San Pedro Latitude Station
An old telegraph pole on the edge of the bluff; probably lost.
The northwest corner of a deserted hotel building standing just above Post *, at the turn of the road leading from San Pedro to White Point.
Rattlesnake Island 2
Bottle buried 2 feet in the ground; stubs 3 feet from the center.
San Gabriel River 2
On the western end of Rattlesnake Island, on the most prominent sand hill, midway between a slough on the right and high-water mark; about 250 feet from the river. (Note 24, p. 617. reference stubs 3 feet from center.)
- Station I
- Los Alamitos
At the head of one of the principal sloughs of Anaheim Creek, in an easterly direction from Anaheim Landing, near and northwest of a fisherman’s cabin. (Note 24, p. 617; three stubs left when recovered in 1873.)
On one of the inside, but most prominent, sand knolls, about 1 ¼ miles southeast from Anaheim Landing. (Note 24, p. 617; stubs 3 feet from center; the west one gone in 1873.)
- Bolsas Creek
On the lowland between Bolsas Chica * and Los Bolsas *, on the line where the firm land commences. (Note 18, p. 617; a stub also placed to the west.)
- Los Angeles Normal School
Los Angeles Magnetic Observatory
The center of the roof of the magnet room in the Normal School grounds, Los Angeles.
Los Angeles Presbyterian Church
The figure of the Angel Gabriel on the spire.
- Los Angeles Signal Service
Baker block; tower.
Los Angeles Longitude Station 1889
Los Angeles Longitude Station 1892
- Los Angeles Latitude Station
Los Angeles Northwest Base Latitude Station
Dominguez Hill Zenith Telescope Station
- Dominguez Hill Meridian Instrument Station
- Rocky Point
Point Vincent N. W.
On a ridge about three-fourths of a mile northwest of Scorpion *; the ground about is very stony.
- East Slope
The shaft of the windmill used for drawing water from a well owned by Albert Timms, in a low valley about a mile from San Pedro and directly on the road.
On the knoll east of a water hole on the right hand of the trail ascending San Pedro Hill from the east, about 1,000 feet above the sea; one of the two places where running water can be found on the mountain in summer.
On the first point beyond the bold spur of the mountain on which Sea Bench * is located, and at a point where the ground is broken by slides; a little back of the edge of the first one. In 1870 the station was marked according to note 18, page 617, but in 1887 none of these marks were found, and a stub projecting 6 inches above the ground, with a copper tack in the top, was left to mark the center of the station.
On the first projecting point of yellow rock and earth along the edge of the bluff from Point Fermin. on a little knob that has a depression between it and the edge of the bank.
On the edge of the next bench up the trail from Yonder *.
On the southwestern point of an isolated hill above the trail along the top of the mountain.
On the edge of the third bench up the face of the long ridge making down to Point Vincent, on the right of the trail.
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.
