Western spotted skunk records in Utah favor rugged, broken ground: Zion National Park’s sandstone cliffs, the San Rafael Swell, and forested slopes in Uinta-Wasatch-Cache National Forest all turn up sightings. That fits the species well. It’s a skilled climber that dens in rock crevices and boulder fields rather than open burrows, and Utah’s canyon country gives it plenty of both.

Reports spike sharply in August, well above every other month, most likely because this skunk is strictly nocturnal and solitary, so most records come from remote cameras or chance night encounters rather than steady daytime observation. NatureServe ranks it S3 Vulnerable in Utah, though its global rank is unassessed (GNR), a reminder that even a widespread western species can have real data gaps at the state level.
