42 NEW YORK STATE MUSEUM 
The magnetite belts are not continuous bands of magnetite; they 
are merely directions, parallel with the structure of the country rock, 
along which are disconnected bodies of minable magnetite. The 
deposits may be grouped as follows: (A) The Orange County 
gone, (B) the Phillips belt, (C) the Sprout Brook belt, (D) the 
Brewster belt, and Isolated deposits, both in Orange and in Putnam 
counties. (See plate 1, index map.) 
A ORANGE COUNTY ZONE 
This zone may be more conveniently described as consisting of 
several groups of mines and pits developed along shorter subsidiary 
belts, together with a number of more or less isolated deposits, 
some of which appear not to be related to the belts just mentioned. 
The mines and openings included within this zone are as follows: 
1 The Sterling group consists of the Lake, Sterling, Steele, Craw- 
ford, Upper California, Lower California, Summit, Tip-Top, 
Brennan and Whitehead mines, lying along a belt that begins near 
the New Jersey state line and which extends about 5 miles to and 
beyond Sterling lake. The Steele mine lies on a ridge at an elevation 
three-fourths of a mile west of Sterling Furnace. The Crawford 
mine is about three-fourths of a mile northeast of the Steele, in the 
same line of strike; it is located near the base of the succeeding ridge, 
in which also lies the Brennan pit, about one-fourth of a mile west 
of the Crawford. 
The Upper California and Lower California mines are located 
about 7000 feet farther north on the south side of the ridge on which 
the Sterling and Lake deposits outcrop; the Upper California lies at 
the base of the ridge, whereas the Lower California is situated a few 
hundred feet southeast, in a swamp near the road. 
The Summit mine is on the northwest side of the same ridge, a 
little less than one-half of a mile from the Upper California, and 
the Tip-Top mine is on the very summit of the ridge, overlooking 
Sterling Lake. 
The Lake and Sterling ore bodies outcrop on the north side of 
the ridge at the foot of Sterling lake, and extend under the lake. 
The slopes of these two mines are about 500 feet apart on the sur- 
face. ) 
The Whitehead mine lies about 2200 feet south of Sterling lake, 
between the highway and the track of the Sterling Mountain Rail- 
road. (See fig. 6.)
