Instrumented readings from the National Park Service Night Sky Program, providing the most accurate SQM and Bortle classifications.
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."
Cloudcap Point
Crater Lake NP
"Moderate winds with occasoinal gusts, combined with high humidity caused some unsteadiness. Otherwise a very clear night. Only small light domes directly visible, with Klamath Falls and ??? Being slightly obscured by cliffs and trees. Fine detail visible in Milky Way, including Prancing Horse near Saggitarius. SQM: 21.47 (1st), 21.41, (2nd), 21.44 (3rd). ZLM of 6.7 in Lyra. Brightening on horizon to SW is a light dome, not the Milky Way, but is obscured by cliffs. I believe a hint of airglow was visually noticeable."
