Igneous, metamorphic, sedimentary, anthropic
Brian Klawiter taught an energetic class on the geology of our region at Denfeld High School last night. We learned about two dozen new terms for “rock” but more importantly, we came to understand the geologic processes that created the rocks around here…
…at the midcontinental rift.
We also learned the human, historical processes that put rocks at the lake walk that are from hundreds of miles away, or more.
Brian is teaching another class next week, on the geology of Duluth architecture. See you there?
