North Point State Park Professional Review and Guide
"See how things have (and haven’t) changed in an area of undeveloped bay-front property where evidence of human habitation dates back 9,000 years. The white-blazed gravel-and-grass trail behind the portable bathroom spits you back onto the road at the gatehouse after just 75 feet. From there, take an immediate left onto the trail, which is initially shaded by tall, thick trees but opens up at 0.2 miles into the 232-acre Black Marsh. The marsh and forested buffer surrounding, protected as a Wildland and Natural Heritage Area, provides a haven for birds.
According to the Maryland Department of Natural Resources, the birds found in and around the marsh include bald eagles, rare American bitterns, Northern harriers, great horned owls, red-tailed hawks, and elusive black rails. The marsh also serves as home to wading birds such as herons and egrets as well as waterfowl such as canvasbacks, goldeneyes, ruddy ducks, mergansers, and scaup. In summer, the white blooms of rose mallows, one of the eight species of rare or endangered plants in the area, cover the entire marsh."
