Mt. Pinos Nordic Ctr
Los Padres NF
"Set up in center of the large parking lot near the Nordic Center/Trailhead seeing good transparency very poor, visibility no more than 20 miles during the day. Marine layer forms early and undoubtedly confines L.A. lights. Bakersfield light dome strongest, but lights of Frazier Park continue light band from north through east to southeast. Glow to north 20 degrees, 15 degrees to southeast, 10 degrees due south. Pretty dark southwest and west. Overhead pretty dark but not exceptionally so. Zodiacal light strong early, through Leo. Gegenschein not seen, too close to Milky Way. SQM 21.55 1st, 21.66 2nd, 21.70 3rd, 21.73 4th."

"Evening begins very hazy, lots of moisture in the air. As night progresses, inversion layer drops below summit, downvalley wind brings clearer and drier air. Lights of cities to west somewhat dimmed by haze, however illuminate the summit on its west side strongly, ruining night vision unless hidden from view. Air very steady, faint stars easily seen near zenith. Western sky very bright to 45 degrees above the horizon. M33 barely visible near zenith, gegenschein barely visible near midnight. Fantastic seeing, excellent observing site for that reason alone. However, do not recommend the summit for public or telescopes, possibly Wolverton parking lot or Wuksachi?"
