Interior visitor viewing area of the Gorge Powerhouse located along the Skagit River in Newhalem, Washington. Upstream from here is the Gorge, Diablo, & Ross Dams to which tunnels carrying water are bored underneath the mountain to here & hydroelectric power is generated. This powerhouse supplies roughly 20% of Seattle's electricity (when it was first built in 1924 that figure was around 40%). Note, bringing in a whole bunch of camera equipment in here that might slightly resemble unusual weapons will probably have security come out to see what you're carrying. Of course I'm still young in appearance so that'll only bring more suspicion.
