How dark the sky really is at Curecanti National Recreation Area
Modelled zenith brightness at the site's coordinates is 21.9 mag/arcsec², which maps to roughly Bortle 2 (what each level means). This is an approximation from the 2024 light-pollution atlas, not a field measurement — and it describes the single point DarkSky lists, not the darkest corner of the park.
This is about as dark as the atlas gets: at Bortle 2 the Milky Way casts visible shadows on moonless nights, the zodiacal light is obvious and the faintest deep-sky objects are within reach of modest optics. Your own light — and the Moon — will be the limiting factor, not the site.
