If you’re looking to escape the light pollution of Ontario, you’re in luck. While enthusiasts often gather at local vantage points for its accessibility, scientific audits conducted by the National Park Service at East Rim Overlook provide the most accurate reading of the regional sky quality, measuring at a Bortle 2.0. Atmospheric stability in the Ontario region is often influenced by local topography, which can help settle the air for high-magnification viewing.

East Rim Overlook
Steens Mountain
"Smoke around horizon and some cloud to the south, clouds increasing as night progresses. A few glare sources visible in the distance, both HPS and metal halide, otherwise virtually no light domes."
Blue Basin Overlook
John Day Fossil Beds NM
"Very clear night! Cloud free, but fire smoke visible to the south and east from N. Calofornia fires. Possibly some smoke to the north low along the horizon. No visible light domes in any direction and only one or two single glare sources in the valleys below from ranches. Exceptionally bright Milky Way with rich detail from Sagitarrius Star Cloud to Cygnus. Easily visble from horizon to horizon. M31 easily visble with naked eye. SQM readings probably a little low due to Milky Way being almost overhead. Milky Way casting shadows with no problem. One of the best nights skies this observer has seen."
