PREHISTORIC WORKSHOPS AT MT. KINEO, 
MAINE. 
C. C. WILLOUGHBY. 
THE porphyritic felsite of Mt. Kineo, Moosehead Lake, was 
one of the chief minerals used for the manufacture of chipped 
implements by the tribes of central and southern Maine. Chips 
and broken implements of this stone were found in nearly all 
of the camp sites and shell heaps which I have examined in 
that state. The oldest New England people of whom we 
have knowledge, and whose art remains were taken from the 
very ancient graves explored by me in Hancock County, Maine, 
in 1892-94, used knives of this 
mineral. 
Although erratic bowlders of 
this stone furnished a limited sup- 
ply of material, the chief source 
was the great cliff of Kineo. 
The southern side of this moun- PRAE Rr 
tain is a mile or more in length 
and rises nearly perpendicularly to a height of several hun- 
dred feet. Its opposite side slopes gradually to the wooded 
plain forming the northern portion of the peninsula. 
In connection with other archaeological work in Maine car- 
ried on under the auspices of the Peabody Museum of Harvard 
University, the writer made two visits to Mt. Kineo, for the 
purpose of locating Indian workshops and learning the manner 
in which the rock was quarried or otherwise obtained. 
The talus slope at the foot of the great cliff of Kineo 
(Fig. 1, 2) is from two hundred to three hundred feet in width and 
extends the entire length of the mountain. Patches of ever- 
greens interspersed with deciduous trees are growing near its 
base, but its surface is practically free from soil. The slope 
of the talus is composed of comparatively small fragments
