Index Town (climbing) Wall and the Tunnel

The small town of Index has a climbing wall that easily beats out any other climbing walls. 
A portion of the Town Wall viewed from Index

The tall wall consist of diorite, and is part of former large magma chamber. The rock has been  partially scoured by glacial ice leaving a fresh clean surface and is one the premier climbing walls in the state.

I and a couple of companions made our way to the top of the wall via a climbing trail a couple of weeks ago using the trail as a short cut to access our destination. At the base of the wall is a covered tunnel.
The tunnel drilled as a test site for a new drilling machine made by the Robbins Company ( in the early 1980s. The tunnel was later used by the University of Washington physics department.
