The UAF Geophysical Institute presents the virtual 2021 Science for Alaska Lecture Series. Tune in at 7 p.m. on Tuesdays to learn about exciting science from measuring the aurora, monitoring whale populations with unmanned aircraft, and participating in the largest Arctic expedition in history. RSVP to watch on Zoom or watch live from the UAF or GI Facebook pages.

The Denali Fault is a long, tectonically active region that snakes through Alaska’s southern interior. The fault marks the boundary where two portions of the North American Continental Plate grind past each other, creating the iconic mountainous terrain of the Alaska Range and causing earthquakes whenever enough pressure builds up between the plates, such as the earth-shattering magnitude 7.9 quake of 2002. In this talk, we’ll explore igneous rocks in the Alaska range and discuss some of the techniques geologists use to determine their age. By carefully studying the geologic features along the Denali Fault, scientists are slowly unraveling the history of this iconic landscape and its role in shaping the Alaska we know and love.

Talks are free and for the public. All ages are encouraged to attend. This is the fourth in a series of six free, public lectures for the virtual 2021 Science for Alaska Lecture Series.
