Upheaval Dome

Upheaval Dome

Natural Attr
Last Updated: July 2026
Type
Geological Formation
Accessibility
One-mile hike with 100-foot elevation gain; rocky terrain; no drive-up viewing available.
Best Season
Spring (April-May) and fall (September-October) offer moderate temperatures and stable weather. Summer daytime heat is intense (100°F+), and afternoon thunderstorms are frequent. Winter is typically passable on paved roads but snow is possible.
Features
Circular anticline with steeply tilted strata; surrounding syncline (downwarp); deformed rock layers visible in cross-section; geological mystery with competing salt-dome and impact-crater origin hypotheses.

Overview

About This Attraction

A circular dome of tilted rock rises abruptly from Canyonlands' layered landscape, its strata deformed as if wrenched by violent force from below. Geologists debate the cause: a salt bubble rising for millions of years or a meteorite impact approximately 60 million years ago. The one-mile roundtrip trail climbs 100 feet to the overlook, where the deformed anticline and surrounding syncline become starkly visible. Recent research supports the meteorite hypothesis, offering a rare window into deep-crust structures normally hidden underground.

Access

One-mile hike with 100-foot elevation gain; rocky terrain; no drive-up viewing available.

Main Features

Circular anticline with steeply tilted strata; surrounding syncline (downwarp); deformed rock layers visible in cross-section; geological mystery with competing salt-dome and impact-crater origin hypotheses.

What Makes It Special

Geologic mystery with competing hypotheses: possible meteorite impact crater (supported by recent research) or deeply eroded salt dome. If the salt-dome hypothesis is correct, Upheaval Dome would represent the most deeply eroded salt structure on Earth.

Best Time to Visit

Early morning (6am-8am) to avoid afternoon heat and lightning. Late afternoon (4pm-6pm) for angled light on tilted strata. Avoid midday July-September due to intense heat and thunderstorm risk.

Safety Considerations

The overlook sits above steep rock faces with significant vertical exposure. Stay behind marked areas and do not approach the rim edge. Keep children close—there are no railings. Do not venture off-trail. Afternoon thunderstorms are common June-September; descend immediately if lightning threatens. The site is exposed; do not stray from marked paths.

Visitor Tips

  • Observe how steeply the strata are tilted compared to surrounding layers—this deformation is key evidence of the impact or salt dome hypothesis.
  • The overlook rim outlines the uplifted dome; look for the surrounding depression (syncline) that rings it.
  • Bring water; no sources at the trailhead.
  • Descend before dark; the rocky trail is tricky in poor light.
  • If lightning threatens, return immediately—this overlook attracts strikes during summer storms.
