Hwy 24 & 285 Trout Creek Pass
Hwy 24 & 285 Trout Creek Pass
  • Trout Creek is traversed jointly by U.S. Highway 24 and US 285.
  • It is passable by all vehicles and is closed only during severe winter storms.
  • The approach from the east is mild, while the west side has a moderate 5% grade.

The old Colorado Midland RR line is in red.

Geologically, the pass is located on a fault that runs along the Mosquito Range.

  • Pennsylvanian black shale and thin gray limestone layers that were laid down prior to the creation of the Ancestral Rockies are visible in some road cuts.
  • These Paleozoic layers were not uplifted during the creation of the Ancestral Rockies approximately 300 million years ago and thus were not eroded to the same degree as other areas to the east and west.

Railroad History

The pass was traversed by the Denver, South Park and Pacific Railroad in 1879, providing the first rail link between Denver and Leadville in the early days of the Colorado Silver Boom.

The Colorado Midland also built a line west from Colorado Springs to Leadville over Trout Creek Pass in the 1890s. Both lines fell into disuse in the 1920s.
