442 A. Guyot— Physical Structure and Hypsometry 
the Indian Head precipitates itself almost immediately into the 
deep clove bearing its name, from which its roaring waters issue 
only two miles below. Both properly belong to the outside 
slopes. 
The main Schoharie Creek originates at the foot of the Scho- 
harie peaks, near the head of the Plaaterkill Clove, from which 
it is hardly separated by a slight swell in the swampy valley 
bottom. It follows closely the foot of the central chain and 
receives just below Tannersville its first affluent, also coming 
m swampy meadows near Haines’ Falls, at the head of the 
Kaaterskill Clove ; these two head streams embracing the chain 
of the High Peak. The creek, keeping the direction of the 
central chain to the west-northwest, flows through Hunter 
village 1609 feet to Lexington, 1820 feet, where it turns with 
the chain to the northwest, to the mouth of the Beaverkill 
Creek, beyond Prattsville, 1164 feet. 
ere it leaves the central chain and, running almost due 
north to the confluent of the Manorkill, it enters the mass of 
the northwestern plateaus, cutting from Gilboa 1033 feet, to 
Middleburg 640 feet, a deep and narrow valley, the bottom of 
which is from 1000 to 1300 feet below the general level of 
the country it traverses, while the occasional flat bottoms in It 
at Blenheim, Breakabeen, Fultonham and Middleburg, rarely 
attain more than half a mile in width. Its course from Blen- 
heim, through Middleburg, Schoharie and Central Bridge, 
where it receives the Cobbleskill Creek, is alternately to north- 
northeast and north. From this place, instead of following the 
broad valley through which runs the Albany and Susquehanna 
Railroad, it leaves it and cutting its way at right angles through 
the high hills which border the Mohawk, it finally enters that 
river near Fort Hunter, after a course of over seventy-six 
miles. 
All the main tributaries of the Schoharie Creek in the 
mountain region, the Eastkill, the Bataviakill, the Manorkill, 
come from the northeast border chain and flow almost due 
west toward the central chain, on the opposite side, where 
they enter the main creek; the Eastkill, three miles above 
Lexington, the Bataviakill just above Prattsville, the Manor- 
kill at Gilboa. Like most valleys of erosion they offer, 10 
their upper and middle course, a succession of flat and open 
basins from which they fall through narrows, in rapids and 
cascades, into the valley of the main creek. The left affluents 
from the central chain, the Westkill, Little Westkill and the 
Beaverkill, are all inconsiderable in length and volume. 40 
the region of the plateaus another Westkill, on the west, at 
Blenheim, and the Keyserskill on the east, at Breakabeen, are 
hardly more than mere torrents.
