Surveyors with the U.S. Army Corps of Engineers capture data for lowering the grade in a steep section of the upper access road during work on the Snettisham Hydroelectric Project. Located nearly 30 miles south of Juneau, Alaska, the project was designed to provide the city power grid with plentiful power for a projected service life of at least 100 years. The first stage was completed in 1973. A second stage completed in 1990 added generating capacity. Many employees regarded its construction as a huge achievement, and it became nationally recognized as a major engineering accomplishment.
