Powdermill is a natural site that also has a human history. In the nineteenth century, the land at Powdermill was home to small communities, family farms, mines, and mills. Few traces of this history remain. Much of the original forest was logged in the early twentieth century, and one section was strip mined for coal. The modern forest is considered second succession because it regrew naturally after these events. Once acquired by the Carnegie Museum, staff rehabilitated some of the existing buildings on site into cabins, laboratories, a museum, and a nature center. Today's nature center was first built in 1983, after a fire destroyed the existing center and staff decided to replace the old museum. It was then expanded upon in 2007, integrating recycled materials and eco-friendly systems, such as the Marsh Machine, which uses greenhouse plants to filter water. Three trails, the Black Birch Trail, Sugar Camp Trail, and Porcupine Ridge, meander through the forest and are marked with interpretive trail signs.2
Scientists from a variety of disciplines visit Powdermill to better understand nature's processes, ranging from migration to reforestation to climate change. In 1961, Dr. Netting and ornithologist Robert Leberman established a permanent bird banding lab at Powdermill, where birds are safely collected, tagged by hand, and then released. Powdermill's dataset, now over fifty years old, provides an insightful and unprecedented look into changes in bird migration over time. The GIS Laboratory opened in 2006 to expand research capabilities using spatial technologies.3
Visitors can explore exhibits, attend programs, hike trails, enjoy gardens, and observe scientific research in action at public days or summer camps for children. Powdermill continues to embody the living museum, a place where nature is studied and appreciated by all who visit.
