Big Faults - Tintina and Denali

Explore the massive Tintina and Denali fault systems in this geology lecture that examines two of Alaska's most significant geological features. Learn about the formation, movement, and impact of these major strike-slip faults that have shaped the Alaskan landscape over millions of years. Discover how the Tintina Fault extends from British Columbia through Alaska, creating a zone of crustal deformation, while the Denali Fault system represents one of the most prominent geological boundaries in North America. Examine the evidence for fault movement, including offset geological formations, seismic activity, and landscape features that reveal the dynamic nature of these fault systems. Understand the relationship between these faults and Alaska's complex tectonic history, including their role in accommodating motion between different crustal blocks. The presentation includes detailed geological maps, cross-sections, and field evidence that illustrate how these fault systems continue to influence Alaska's geology today. A live Q&A session follows the main presentation, allowing for deeper exploration of specific aspects of fault mechanics and Alaskan tectonics.
