According to new research, the three sites spread along an approximately 620-mile portion of today’s Denali Fault were once a smaller united geologic feature indicative of the final joining of two land masses.
- That feature was then torn apart by millions of years of tectonic activity.
- The research focused on formations at three locations: the Clearwater Mountains of Southcentral Alaska, the Kluane Lake region of Canada’s southwestern Yukon, and the Coast Mountains near Juneau.
- The Denali Fault is a strike-slip fault, a place where two chunks of continental crust slide past each other.
- The Denali Fault, the fastest moving and most active fault in Interior Alaska (USA), cuts through the heart of the Alaska Range and Denali National Park and Preserve.
