  • The glacial diversion of the Farmington River from its probable original path to New Haven northward through the Tariffville Gorge is a classic glacial diversion which is unique in Connecticut.
  • Rare plant and animal habitats are associated with geologic features such as the Traprock Ridge, the Tariffville Gorge and the Sandplains.
  • A billion year time span of earth history and broad diversity of features lies within a 35.1 square mile area.
  • The alluvial soils that formed under glacial Lake Hitchcock and glacial Lake Farmington which are among the best farmland soils of the United States. Due to the glaciation history it has the highest soil diversity in Connecticut and one of the most complex soil systems in the United States. There are over 200 different soil types in Connecticut, 50 percent are represented in the Farmington River Valley.
  • In turn, the biodiversity and habitat complexity of the Study Area is strongly influenced by this soil complexity. One of the original soil surveys was conducted in 1899 to promote tobacco cultivation in the lower Farmington Valley.
