Marblemount, WA
Taken March 2007

Status unknownCheck attempted on "as of" date (usually via GSV in this case), but status of light could not be determined at that time, usually as fixture could not be found again
as of Jul 2019
Marblemount is a tiny place west of the North Cascades National Park, on Hwy 20. It's about 35 miles from the coast, and Mt Vernon/ Sedro-Woolley. This light isn't actually in Marblemount, but near to it, on the right as you go west on 20. If you get the fullsize pic, you'll see it looks a lot like the GE Powerglow. Powerglow A1000 and A4000 post tops are much loved amonst folks who like these things (!), this one is either a copy, or something that looks unintentionally like the GE design. Manufacturer and date unknown, there is one other known picture of these fixtures, but it's copyrighted so unlikely to appear here.
Update 4-2009:Thanks to a tip by Jim Terry, we now know
this fixture is made by Sterner.
