We walked up the hill on the east side of the creek, after some heavy brushwacking we came across this artifact, the remains of a wooden pipe.
The blue map shows the location of the water tank and water pipe completed in 1920. On the right is a 1930 photo, the area cleared for the water pipe is very distinct.
We found two of these pipe clamp things.
On the way back to civilization we stopped at the Pickett Historical Museum in Index. Lee Pickett lived in this house, he was a photographer for the Great Northern Railway and also took quite a few pictures of Alpine. The University of Washington has a large collection of his photos here.
