If you’re looking to escape the light pollution of Anaconda, you’re in luck. While enthusiasts often gather at Blue Mountain Observatory for its accessibility, scientific audits conducted by the National Park Service at nimí·pu· Camp provide the most accurate reading of the regional sky quality, measuring at a Bortle 2.0.

nimí·pu· Camp
Big Hole NB
"Set up camera equipment on the trail to the camp. Clouds in the afternoon all cleared out by 9:00 pm, though it appeared as if some fire smoke moved through the northern horizon later in the night. Excellent night sky viewing from this park, rivaling sites on the Colorado Plateau. A single yard light on a ranch building 2.5 miles north was bothersome, otherwise no visible lights seen from this location. A very faint light dome from Butte (60 miles distant) and nothing apparent from Wisdom, the nearest community (9 miles). Very fine detail visble in the Milky Way, with the Prancing Horse easily seen and the dust lanes in great detail. Stars are visible to the horizon in the south. Saw limiting magnitude star of 7.2 in Draco. Mars and Jupiter very bright to the SE and SW."
Lower Madison River
Yellowstone NP
"Evening started out with widespread thunderstorms, which slowly dissipated through the night until skies were almost cloud free. The light dome of West Yellowstone (only 1.5 miles to the west) is very prominent and dominates the western horizon. Bozeman is barely visible to the north, likely due to low clouds in the distance. Even with the bright lights of West Yellowstone, you can see some good detail in the Milky Way before it becomes obscured by the light dome."
