Geologist Becky Nesel led a fun and fascinating walk through over a billion years of geologic history at the Thompson Pond Preserve. On a comfortable August evening, local geologist Becky Nesel led guests on an exploration of the geology of Stissing Mountain and Thompson Pond Preserve. She first guided guests through the rock cycle and the geologic history of the land - from the first mountain building events - known as orogenies - over a billion years ago, clear through to the last glaciation in this area, when the Laurentide ice sheet covered the land and then retreated. She showcased billion year old gneiss that had been exposed when the glacier scraped away younger rock and can be seen today on the slopes of Stissing Mountain. Guests then learned of the awesome power of glaciers to create new landforms when Becky explained the origins of Thompson Pond as a glacial kettle. A big thank you to Becky for volunteering to guide this walk! We're planning on more geology walks with Becky, so keep an eye on our events page for more opportunities to learn about the thrilling history of the land as viewed by a local geologist.
