2012 – GEOLOGICAL SETTING OF A WETLAND
(Curated by Hans Trettin, geologist, and mounted by Lynne Jordan)
Section titles included:
– Post Glacial Crustal Rebound and Soil Development
– Ice Age Sediments and Events
– Granitic Basement
Hans Trettin also explained the reason for the natural white sand beaches on Hague Lake – and how they had been formed.
Christian Gronau, another local geologist, contributed a painting that showed the Earth’s core, putting the geology of Cortes somewhat into perspective.
Sadly, not long after this exhibit opened, Hans Trettin passed away.
