I might suggest you take a look at some of the Archaeological Reports done in an
d
around The Nez Perce National Historical Park, Spalding, Idaho. Watson's Store
was started there in 1911 and open until 1964. Work was done in the Lapwai Valle
y
by Roderick Sprague and Caroline Carley in the Spring (AP-MAY) of 1980,
University of Idaho. It might be helpful.
