Fremont Indian State Park
The largest known Fremont village, uncovered by an interstate — and a Bortle 2 sky, because Clear Creek Canyon walls off the valley lights.

Overview
Fremont Indian exists by accident: in the early 1980s, crews cutting Interstate 70 through Clear Creek Canyon uncovered the largest Fremont village ever found. The village is gone — the highway went through — but the rock art, the granaries and the artefacts were saved, and the park was built around them. What makes it a dark-sky park is the canyon itself. Clear Creek is walled, and the walls stand between the park and the lights of the Sevier Valley. The result is a Bortle 2 sky and an SQM-L average of 21.77 — as dark as Bryce Canyon's — measured a few hundred yards from an interstate. It is the clearest small-scale proof of the thing this whole project keeps running into: geometry beats distance.
Getting in

Safety & conditions
Activities
Stargazing
Certified 2021. Bortle 2, SQM-L 21.77 — as dark as Bryce — measured beside Interstate 70, because Clear Creek Canyon walls the valley lights out.
Season: Year-round; new-moon best.
Hiking
Short canyon trails linking the rock-art panels, plus longer routes up onto the rim.
Season: Spring through autumn.
Camping
Castle Rock Campground, up the canyon.
Regs: Reservable through Utah State Parks.
Night Sky
Dark Sky Park Certified 2021 Bortle 2 21.77 mag/arcsec²
Bortle 2 in a canyon a few hundred yards from Interstate 70, and the canyon is the reason. Clear Creek is walled, and the walls stand between the park and the Sevier Valley. Step up onto the rim and the sky is a different one. What else moves it: moon, and headlights on I-70.
What the sky does here
-
Typical
Bortle Class 2: The Wilderness Has Its Own Light
Under a Class 2 sky, darkness is nearly natural yet the landscape remains emotionally legible. The Milky Way becomes architecture, still water can carry a second sky, and the night feels less alien than complete.

Only when
Bortle Class 3: Civilization Beyond the Rim
Up on the canyon rim, or anywhere the Sevier Valley lights clear the walls — the shelter that makes this park dark is a few hundred feet of rock, and it does not follow you up.
Geology
Volcanic country — the canyon is cut through welded tuff from the Marysvale volcanic field. The soft tuff is why there is so much rock art here: it takes a peck easily and holds it.
Province: Colorado Plateau — western margin, at the Basin and Range transition
Rock types: volcanic tuff, rhyolite
Major formations
Also present: Joe Lott Tuff
Ecology
Biomes: pinyon-juniper woodland; riparian corridor along Clear Creek; sagebrush
Flora
- pinyon and juniper
- cottonwood along the creek
Fauna
- mule deer
- elk
- mountain lion
- golden eagle
A canyon corridor between the Tushars and the valley — a wildlife route as much as a park.
History
Clear Creek Canyon lies within the ancestral homeland of the Ute and Southern Paiute peoples, whose connection to this country continues, and the Fremont people who lived here left the largest known village of their culture. It was uncovered in the early 1980s during construction of Interstate 70; the village site was largely destroyed by the highway, and the park was created in 1985 to hold what was saved.
Modern issues

An interstate through the middle
Status: permanent
I-70 runs through Clear Creek Canyon, a few hundred yards from the park. The canyon walls are what keep the sky dark.
