AVALLI COU 
NTV. 
A station in the base expansion, situated 15 miles northeast of 
Hamilton, on a bald summit of the range on the eastern side of the 
Bitterroot Valley and about 4,000 feet above it. It can be reached by 
following up Willow Creek from Corvallis to a half-finished log cabin ; 
thence up a leading spur to the station, the latter part of the way 
being through lodge-pole pines and difficult to travel. This station 
can be used in the extension of triangulation in any direction excepting 
eastward. 
Station mark: A lone tree, trimmed.
