AJ Road
Redwood NP
"Marginal site on a turnout with a view toward Crescent City but east almost enitriely blocked by trees and hillside. As time progresses trees to the west will block this view. However, on this date a reasonable monitoring site for Crescent City impacts. Seeing very good, transparency good. Sky is significantly impacted to the zenith because of proximity to town, but still fairly dark with good visibility of faint stars. Observer sick with chills and flu-like symptoms, no visual observations made."
Hillman Peak
Crater Lake NP
"Site on summit of Hillman Peak, highest point on Crater Lake Rim, small area to set up instrument. Seeing very good transparency good. Fire smoke in many quadrants in the distance may obscure sky glow from distant cities. On this night no areas of the light domes are bright enough to hinder dark adaptation. Klamath Falls and Medford most obvious, but light domes do not extend beyond 10 degrees above the horizon. A nearly pristine sky."
