December 28 , 2024 12 hrs 0 min 19 0
  • The Denali Fault is a significant right-lateral strike-slip fault in western North America.
  • It is stretching from British Columbia, Canada, to central Alaska, USA.
  • It marks the boundary between the Pacific Plate and the North American Plate, with the Pacific Plate actively subducting under the North American Plate.
  • This subduction causes significant geological stress and deformation.
  • These three geologic sites along the Denali Fault were once part of a single feature that united two landmasses’ millions of years ago.
  • Clearwater Mountains, Kluane Lake, and Coast Mountains linked by 300 miles of horizontal movement.
