Furnace Hills Conservation Area within the Pennsylvania Highlands
Rising to an elevation of 1,000 feet, the Furnace Hills conservation area forms the central forested hub of the Pennsylvania Highlands and a major stronghold for natural resources. Located east of the Susquehanna River, on the borders of Lancaster and Lebanon counties, the Furnace Hills landscape encompasses approximately 31,000 acres of land, including many state game lands.
Natural Resources
The focal point of this area is the 6,000 acre Middle Creek Wildlife Management Area, operated by the Pennsylvania Game Commission. It is one of just six globally Important Bird Areas in Pennsylvania, as well as a designated Important Mammal Area. The Furnace Hills is a critical sanctuary for migrating waterfowl, most notably snow geese and tundra swans. More than 280 species of birds and other animals are found in the forests, lakes, fields, ponds, and marshy pothole habitats of the Furnace Hills. Nesting bald eagles, ospreys, hawks, spring warblers, great blue herons, red fox, and white-tailed deer are found here.

Furnace Hills conservation area overlaps with a High Protection Priority area designated by the Pennsylvania Natural Heritage Program, Priorities for Climate Change Connectivity in Pennsylvania. This project focuses attention on overall high priority portions of the Climate Change Connectivity network which are currently unprotected.

Historical / Cultural Resources
The Furnace Hills provide the backdrop for many historic sites from the nation’s iron era. The iron industry was the economic backbone of this area for more than 200 years. The nearby Cornwall Ore Banks was once the greatest known deposit of iron ore in the country. Besides iron ore additional minerals such as cobalt, copper, silver, gold, and others were also mined. Cornwall Furnace produced various cast iron products, pig iron, cannon, and cannonballs during the Revolutionary War, and gun blocks during the Civil War.

The unique village of Mount Gretna was a station and recreation area on the former Cornwall to Lebanon railroad. The distinctive character of Mount Gretna is typical of the small communities and human history of the Pennsylvania Highlands Region.
Recreational Resources
The Horse-Shoe Trail is a main recreational amenity extending almost the entire length of the Furnace Hills, which this section co-aligns with the Highlands Trail of Pennsylvania. Historically, it was used to transport goods to and from the numerous iron furnaces and forges in the Pennsylvania Highlands. This and other recreation areas in the Furnace Hills are frequently associated with State Game Lands, which provide outdoor recreation opportunities ranging from hunting and fishing to hiking and boating.
