Chipmunks and groundhogs appear. The weather may change quickly. Pink azalea blooms in late May followed by mountain laurel in June. Migrating birds in their breeding plumage are numerous. The park visitor encounters new sights, colors, sound everywhere.
Summer brings a mantle of deep green to the ridges and hollows.
Many birds are nesting, and the catbird, chestnut-sided warbler, indigo bunting, and towhee abound. Fawns are often seen. The variety of wildflowers increases as the summer progresses, and by late summer many species cover the roadsides and open areas. Fall is the season of brilliant colors and clear, crisp days. Many people come to the park to see the fall color, which usually is at its best between October 10 and 25.
