Harbor SEALs @ Black Rock Forest

Harbor SEAL seniors celebrate on a peak overlooking Black Rock Forest

This weekend, the Harbor SEALs trekked up to Black Rock Forest in Cornwall, New York to complete a one day ecology workshop sponsored by a Toyota Grant. We monitored the physical-chemical parameters of Cascade Brook and determined the health of this pristine ecosystem. With chemical and biological sampling gear in hand, we took a roller coaster-type ride up to the Brook on pick up trucks and got to work early Saturday morning. The SEALs team were able to determine that, although the Brook’s waters are pristine, it’s not immune to the effects of acid rain. We found pH values of around 5 to 6 units. Surveying the vertebrates and macroinvertebrates, the SEALs determined that the Brook has Type II organisms that are semi-tolerant to pollutants and thus are experiencing some stress. It wasn’t all work though as the team celebrated Ameena’s 17th birthday, hiked up to one of the Forest’s peeks, played board games, and delightfully cooperated in preparing meals. Thanks Rebecca and all for a great time! (For more pictures, click here: IMAGO)
