Alpine, UT: how dark is the sky here?
Alpine's sky measures rural here. Little local light dome. Most stars are visible; the Milky Way is faint but often findable away from town lights. Only 7.5% of the 3,206 cities measured here read darker than Alpine.
This comes from a satellite measuring light radiating upward, not a person's eyes on the ground, so it isn't the same as a Bortle class, though the two track each other closely.
How far Alpine is from a meaningfully darker sky
Heber, UT, about 21 miles away as the crow flies, measures in the dark sky band, one step darker than Alpine. Actual driving distance will run longer than that straight-line figure.
Heber, UT is itself still a measured city, not a designated dark-sky park, this only compares against the 3,206 places this dataset covers.
