This land is very flat and swampy. Part of the east end of Long Pond shows evidence of being a depression known as a “kettle”, formed as the ice sheets melted. The land that lies further east beyond the preserve boundary is steeply ridged and forested.

This is one of the most sensitive ecological areas in Thompson if not in the entire Wyndham Land Trust area. The pond is used by migrating water birds including mergansers and grebes. It is separated by Jerry’s Swamp from the Wieloch preserve. A study of the area was undertaken by the Eastern Connecticut Environmental Review Team in 2007 and they conducted a Natural Resource and Habitat Environmental Study and a report was issued. A new wild life survey was carried out in 2017.
