2025 GSC ANNUAL FIELD TRIP
"On the Mapping Menu in Western Connecticut: Main Course of Migmatites and Metasediments with a Side of Basin"
Examples of lithologies from the general area of the field trip that we will sample during our field-trip buffet: banded migmatite biotite gneiss (left), garnetiferous schist (center), and Pomperaug basin arkose (right). Images courtesy of Bill Burton.
Join us for the society’s annual spring field trip! Trip leaders Bill Burton and Bill Devlin will guide us on a 10-stop field trip in the Woodbury–Roxbury area. We will sample a broad buffet of lithologies and structures and, with the help of ancillary data, put together a depositional and tectonic history for this geologically complex area that underwent Paleozoic contractional and Mesozoic extensional tectonics.
The guidebook was originally prepared for a 2020 field trip that was canceled. It will be augmented during the trip with posters that illustrate recently obtained data and the field trip leaders’ current thinking.

Ten Thousand+ Years of Long Island Sound History: From Marine Inundation to Human Domination
by
Joop Varekamp and Ellen Thomas
by
Joop Varekamp and Ellen Thomas
Joop and Ellen spoke about the formation and subsequent history of Long Island Sound. Ellen covered the fossil record of the LIS sediments, including recent/ongoing work with her PhD student at Yale on genetic data on invasive foraminifera in the Sound. Joop spoke about dating, shifts in the carbon cycle and temperature–dissolved oxygen–salinity records, the sea level rise record in conjunction with crustal rebound scenarios, and pollution over the last 400 years.

2024 GSC ANNUAL LATE SUMMER PICNIC: Geology of the Hartford Basin and Cookout at Dinosaur State Park
A pre-picnic field trip was held on September 14 in the Hartford basin followed by a late afternoon picnic on the grounds of Dinosaur State Park. On the field trip, Paul Olsen guided us through a series of stops in the Hartford basin that illustrated concepts he discussed during his talk at last year's annual meeting. At the picnic, we had the opportunity to relax and enjoy the company of like-minded geologists. The GSC provided the picnic fare.

The Geological Society of Connecticut is pleased to announce a summer picnic on September 11 at Rocky Neck State Park in Old Lyme. We will meet at noon at a cluster of picnic tables in a wooded area next to the bird observation platform near the beach parking lots where we can also grill. Entry to the park is free with Connecticut-licensed cars but an event registration fee of $10/attendee will cover the food/supplies GSC will provide (hamburgers, veggie burgers, hot dogs, corn, watermelon, chips, desserts, and soft drinks). Feel free to bring additional food and beverages. The event is BYOB (alcoholic beverages are allowed in the picnic areas). Please register by September 9 to reserve your meal.
During the afternoon we will hold an informal field trip discussing both glacial geologic and shoreline dynamic features and bedrock geologic and quarrying features. These areas are covered in depth in field trip guides from previous trips (NEGSA 2012: DEEP guidebook #9 and GSC 2015: GSC guidebook #6), which we will have on hand to share.
