Powdermill is as a field station of Carnegie Museum Of Natural History for long-term studies of natural populations: their life histories, behaviors, and ecological relationships.
In 1956, General and Mrs. Richard K. Mellon and Mr. and Mrs. Alan M. Scaife presented to Carnegie Institute, for the use of the Natural History Museum, eleven tracts of land totaling 1,160 acres. Over the next several years, additional acreage was added to the reserve through other generous gifts, and today, Powdermill Nature Reserve offers over 2,200 acres of woodlands, streams, open fields, ponds, and thickets.
From April to October, the reserve is open Wednesday through Saturday, 8:00 a.m. to 4:00 p.m. and Noon to 5:00 p.m. on Sunday.
From November to March, the reserve is open Monday through Friday, 8:00 a.m. to 4:00 p.m. and on weekends as needed for special events and programs.
The reserve has its own parking facilitites.
