Finzel Swamp Preserve is an approximately 326-acre property owned by The Nature Conservancy (TNC). It is located partly in Garrett and partly in Allegany County in a topographic depression between Big Savage and Little Savage Mountains in what is called a “Frost Pocket.” This is a climatological phenomenon that is more common farther north, and results in cold air being trapped at the site. The result is a rich habitat containing many rare, cold-tolerant plants that are more common farther north. The cetrpeices of the preserve is Cranberry Swamp, which is a relict of the last Ice Age and is at least 15,000 years old. The American larch trees (Larix laricina) that occur here are unusual in Maryland, in fact constituting one of only two known stands in the state. Other northern plants that occur in Finzel Preserve include alder and red spruce.You can read more about the plant communities at Finzel in the Nature Conservancy’s Visitor Guide. The unusual plants in the swamp host an interesting set of breeding birds, including Alder Flycatcher and Northern Waterthrush.

From the parking area, take the obvious trail heading east to Cranberry Swamp. The trail and a series of boardwalks will carry you over the swamp and through rich vegetation to either side. The trail is usually dry but waterproof footwear is recommended, just in case. The trail continues past the swamp, crossing from Garrett County into Allegany County, arriving at a pond set amid an old scrubby field. The trail circles the pond and then will bring you back to the main trail to the parking area. If you’re an eBirder or a county lister, be sure to note that the parking area and the start of the trail through the swamp are in Garrett County, while the pond and old field are in Allegany County.

For first-time visitors to Finzel Swamp, we highly recommend downloading and following the Nature Conservancy’s Finzel Swamp Audio Tour, which will help you understand the special habitats found here. Another good resource is the MD Department of Natural Resource’s Guide to Finzel Swamp Natural Area.
