Stay Connected with Nature

In 2000, the Baltimore environmental community came together to celebrate the 30th Anniversary of Earth Day with a mix of hands-on activities, environmental education, and outdoor recreation. Long-time Gunpowder Valley Conservancy volunteer, Charlie Conklin, aspired to recreate the celebration and formed a steering committee for the 50th Anniversary of Earth Day. While 2020 had other plans, it could not deter our commitment to collaborating to improve our part of the Chesapeake Bay watershed.
