Atlantic Highlands Cretacic — Prather. 173 
25 feet in thickness and extends from Bay View avenue in 
the direction of Hiltons some 800 feet. It is a s^nd as 
shown when separated and examined under the miscoscope 
although it appears at first sight to be a compact clay. It is 
sometimes found as one bed, or may be made up of a num- 
ber of small beds or lenses of only local extent varying in 
thickness from 2 feet to 8 feet (see lenses 4 and 5). The 
color varies from white to yellow, salmon, brown, orange, 
and red. It is made up almost entirely of quartz grains 
with grains of iron, probably magnetite, mica, and some 
glauconite. The quartz grains are both angular arid round- 
ed and are generally of uniform size, although larger and 
more rounded quartz grains are noted. It rests above the 
Marshalltown clay and below the Navesink and Mt. Laurel, 
although the upper Marshalltown clay seems to be about 
the same age. Sometimes it is coarse like an ordinary sand, 
and again it is finer grained like a clay. This is probably 
the upper part of the Hazlet sand of Clark. Part of it may 
correspond to the Wenonah sand of the New Jersey survey, 
although on account of local variation it does not seem to' 
fit this so well, and is therefore given a local name. 
Bay View Avenue Lenses, (1), (3), (4), and (5). 
These four lenses are included as part of the Bay View 
Avenue sand and as part of the Mt. Laurel sand. No. (1) 
is 4 feet thick and 120 feet long; No. (3) is 4 feet, 5 inches 
thick and 120 feet long; No. (4) is 2 feet thick and 130 feet 
long; and No. (5) is 2 feet thick and 70 feet long. 
No. (1) is very fine grained and of a light color. It 
contains quartz and mica but has so much fine clay as to 
render it a clay rather than a sand, and causes it to break 
into hard lumps. 
No. (3) is much coarser and more arenaceous than No. 
(1) and contains more glauconite and more quartz and less 
fine clay. It is a brown color and readily separates into a 
sand. Nos. (1) and (3) are part of the Mt. Laurel sand. 
No. (4) is fine grained like No. (1) but of coarser grain. 
It breaks up into lumps and has so much fine clay as to 
make it a clay rather than a sand. It contains quartz and 
mica but the clay predominates. It is of a light grey color 
and contains very little glauconite.
