Obstruction Point
Olympic NP
Local Relevance
The scientific findings at Obstruction Point provide Cottage Lake residents with the most reliable data on regional atmospheric stability.
"Transparency remarkably good after yesterday's fire smoke, seeing very good. Few high clouds to the west and north, remnants of fire smoke to the northeast. Direct glare from many very bright lights on Vancouver Island and a few Port Angeles lights, otherwise the high ridges of the Olympic Mountains effectively block any other glare from the Puget Sound area. After moon sets, the zenith is quite dark with the Cygnus Milky Way very detailed, but a broad and fairly bright light dome toward Seattle and Puget Sound dominates the eastern sky. Excellent site for monitoring. Perhaps an area 30 degrees in diameter near the zenith offers reasonable visual observations."
Burroughs Mountain
Mount Rainier NP
Local Relevance
For observers in Cottage Lake, Burroughs Mountain serves as the definitive baseline for high-altitude transparency and localized skyglow data.
