Today we learned all sorts of fun things about outcrops. We looked at some ash fall remnants, tephra, that came from about 1469. We figured out that the wind was blowing east on the day of the eruption and we got to know an amazing geologist that specializes in tephra, Heather Wright.

She taught us about the different layers, when they erupted and how strong the eruptions were when they occurred. We found a site that the tephra wall was 1 meter tall. It was extraordinary. She was a very experienced scientist and explained things very well. She goes all over the world to help people with management of volcanic crises. She works with VDAP. We were very appreciative to be able to work with her this week.
