Settlements
The recent building of the Chicago.
Milwaukee & Puget Sound Railway
caused settlements to be made along
Its line--some of the evanescent type
always linked with the construction Of
railways In a new region others, like
Avery dependant on railways con-
tinuing operation. Away from the
railway the only habitations are few
forest-ranger stations and miners
cabins mainly near the ST. Joe River,
and homesteaders' cabins in thedrain-
age basins Of Marble Greek and Clear
water River
Supply Points
Avery Is convenient Quitting
point for prospectors and others desir-
ing to explore the region to the south
and west, or up ST. Joe River as far
as Goddards. Saltese and De Borgia,
Montana. are the most convenient
supply points for the area reached by
way ot"eo iiHC anu Lie DOTEld trails.
In addition several smaller supply
points lie along the railroad
Surface
Steep slopes characterize the sur
face of at least ive-sixth of the area.
The remainder, Of level or gently
sloping ground, is found mainly in
ridge submits or high cut rock ter
races. There is proportinately a
small amount Of level ground in the
valleys of St Joe River below Avery
and upper North Fork Elevations
along st. Joe River are 1900 feet at |
Big Creek, $500 feet at Avery, and
$500 feet at Conards. The highest |
SUBMITS attain elevations of $500 to |
1900 feet. In general the relief of the |
ridges separating the main streams
is 1000 to 5000 feet.
The flats at approximately 5000 feet |
elevation now forming the SUBMITS of
ridges are apparently remnants of an
extensive peneplain above which
Wards Peak, the Three Sisters, and
other submits rise as monadnocks.
This peneplain is probably to be
correlated with the extensive dissected
plateau of the Clearwater Mountains
and with the level ridge SUBMITS ex-
hibited In the Occur d'Alene district to
The north and beyond In addition.
remnants of later but less extensive

Drainage
The intricate drainage system of st. II
oe River is evidently inherited from "
he former base-evels, upon which the u
Ereams flowed in sluggish winding II
purses. The main stream and It's a

steep, st. Joe River having an .

aintain similar grades well toward a.
