The April Tate Talk will feature lava lakes, volcanoes, and more. Presented by Kent Sundell, Ph.D., the talk will take place at the Tate Geological Museum on Wednesday, April 1, at 6 p.m.

Geological interactions along the Western United States have led to a wonderful variety of volcanoes within Wyoming. According to Sundell, over the past 65 million years, the state has witnessed an extraordinary range of volcanic features, from towering 20,000-foot-andesitic stratovolcanoes with vast lava lakes filling the valleys between them, to fluid, orange-glowing flood basalt lavas punctuated by the most massive explosive rhyolitic ash eruptions of all time.

Sundell’s talk is free and open to all and will be live at the Tate or available to watch on the museum’s Facebook page. The Tate Geological Museum is located at the southern end of the Casper College campus, near the T. rex sculpture.
