One of Juneau's back-up water and electrical sources lies behind the Salmon Creek dam which was built in the 1910s by the Juneau-Douglas mining company. We had a very pleasant hike though we took some ribbing from the Boston Marathon gang (which includes Bishop C). Hey, we were bird watching, doing some minor trail improvements and heck, taking pictures.
Salmon Creek is a pretty easy hike. 7 miles, 1100 ft elevation gain. Compare Thunder Mtn.'s 6 mile/8 hour trip to Salmon Creek's 7 miles/4 hours.
