For a Safe Hike
• Wear sturdy shoes to protect your feet.
• Carry the proper safety equipment, like a first aid kit and a poncho.
• Stay on the trail. If you hike off the trail, you might get lost or damage fragile habitats.
• Carry drinking water. DO NOT drink from streams, springs or lakes without properly treating the water first!
• Observe wildlife from a safe distance. Do not try to get close to wild animals.
• Check the weather before you hike. It is not safe to hike in thunderstorms or when heavy snow is expected.
• Tell someone where you are going and when you will return.
• A cell phone can be useful for calling for help, but many sections of the park do not have cell phone coverage.
Appalachian National Scenic Trail
Running through the heart of the park is probably the most famous footpath in the world, the Appalachian Trail (A.T.). The 2,186-mile long trail traverses the Appalachian Mountains, stretching as a continuous footpath from Springer Mountain in northern Georgia to Mt. Katahdin in central Maine. The trail is marked with white blazes, which can be seen near the Pine Grove General Store, Appalachian Trail Museum, Fuller Day Use Area and on the rail trail.
Half-gallon Challenge: About 2,000 people attempt to hike the entire A.T. in one year. These long distance hikers are called thru-hikers and most pass through the park from late spring through the summer months.
About one out of four thru-hikers will complete the whole trail. Reaching Pine Grove Furnace State Park is a milestone. The halfway point of the A.T. is several miles south of the park, in Michaux State Forest.
To commemorate the completion of half of the journey, it is a thru-hiker tradition to attempt the “half-gallon challenge” of eating one half of a gallon of ice cream in one sitting. On a summer day, it is common to see hikers working on the challenge at the Pine Grove General Store.
Hiking the A.T.
The Appalachian Trail is a popular destination for short-term backpackers and day hikers. About 2 to 3 million people walk a portion of the A.T. each year. Pine Grove Furnace State Park is a popular staging point for short term backpacking on the Appalachian Trail. Boiling Springs to the north and Caledonia to the south are each about a 20-mile hike from Pine Grove Furnace.
Overnight parking is available for backpackers in a special section of the Furnace Stack parking lot. Hikers should register their car and supply contact information and an itinerary at the park office.
Information, maps, guides, shuttles and more are available. www.appalachiantrail.org

Pine Grove Furnace
In 1764, partners George Stevenson, Robert Thornburgh and John Arthur built an iron furnace along Mountain Creek. They named it Pine Grove Iron Works. It manufactured ten plate stoves, fireplace backs, iron kettles and possibly munitions during the American Revolution.
In 1782, Michael Ege, a rising Cumberland County iron mogul, purchased the iron works. Over the next 32 years, Ege grew his business until he was the sole owner of Pine Grove, Cumberland, Holly and Carlisle iron works.
Michael’s oldest son, Peter Ege, inherited Pine Grove Iron Works. In 1829, Peter built for his wife, Jane Arthur Ege, a red brick, English Tudor mansion. Jane died at Pine Grove in 1841 and was laid to rest in the Pine Grove Cemetery next to her son George Washington Ege, who had died in 1831.
Peter expanded his iron works in 1830, building Laurel Forge, which reheated and hammered cast iron from Pine Grove Furnace to produce wrought iron, a bendable metal that could be formed into many shapes.
The financial panic of 1837 bankrupted the Pine Grove Iron Works. At a sheriff sale the following year, Frederick Watts and his law partner Charles Bingham Penrose purchased Pine Grove to try their luck in the iron business. Watts went on to found Penn State University in 1855 and served in 1871 as Commissioner of Agriculture for President Grant. Penrose was a state senator and Solicitor of the Treasury for President Harrison.
In 1864, Jay Cooke and Company bought the iron works and formed South Mountain Iron Company, bringing in Jackson C. Fuller to be the furnace manager to run the daily operations, while the business affairs were taken care of in Philadelphia. The new company built South Mountain Railroad to bring raw materials to the furnace and move the iron products to market.
Jay Cooke is often called the “Financier of the Civil War.” He raised about $1.2 billion through the sale of federal treasury notes. Taking only a small commission on the sale of each bond made Cooke the wealthiest man in America by the end of the war. He then bought the Northern Pacific Railroad, which failed in the poor economy and depression after the war. Cooke was bankrupt and moved into his son-in-law’s home. The closing of the banking house of Jay Cooke and Company caused the financial panic of 1873.
The South Mountain Iron Works went up for sheriff sale, but no one bought it. In 1877, the railroad and iron works were sold separately. Through his friend Fuller, Cooke bought back the ironworks, forming the South Mountain Mining and Iron Company.
Future founding member of the Pennsylvania Forestry Association, John Birkinbine, became the furnace’s engineer. Concerned over Pennsylvania’s dwindling forest reserves and wanting to show that charcoal iron furnaces could be fired with alternative fuels like coke and coal, Birkinbine renovated the furnace in the winter of 1878. Charcoal remained the primary fuel of the furnace, but the furnace no longer had to shut down when charcoal supplies were exhausted. Birkinbine also increased the size of the furnace, which produced 6,000 net tons of cast iron in 1883, the peak year of production.
But, new technologies were quickly putting small iron producers out of business. Pine Grove Furnace went out of blast in 1895, ending 131 years of iron making on South Mountain.
Pine Grove Furnace State Park
In 1913, the 17,000-acre Pine Grove Ironworks was sold to the Commonwealth of Pennsylvania to be part of the new Forest Reserve system. Much of the land became Michaux State Forest, and part became Pine Grove Furnace State Park. Fuller Lake, an iron ore quarry, which had filled with groundwater when mining ceased, became a popular swimming area. Laurel Lake had supplied waterpower for Laurel Forge. Today it is popular for fishing and swimming.
In 1933, the Civilian Conservation Corps (CCC) established Camp S-51. The CCC boys built roads, trails and facilities until 1941.
Some of the historic buildings dating back to the charcoal iron community still stand and include the furnace, ironmaster’s mansion, clerk’s office, stable, grist mill (now the Appalachian Trail Museum), the second iron master’s mansion (now the park office) and several residences. Remnants of raceways, charcoal hearths and related manmade features are still discernible.
In 1977, Pine Grove Iron Works was entered in the National Register of Historic Places.
The diverse habitats of Pine Grove Furnace State Park support a variety of wildlife through all seasons. The historic use of the area during the iron furnace period created a varied combination of open areas, wetlands, and vegetation that make the area unique for wildlife.
Spring and fall is the time of bird migrations. The forest, interspersed with ponds and wetlands, makes the park a rest stop for many migrating forest birds. Warblers, vireos and thrushes stop to rest and eat before flying on to their breeding or winter homes.
Laurel Lake and its shoreline wetlands are a beacon that lures waterfowl. Merganser, Canada goose, mallard, loon, teal and many other ducks can be seen swimming, diving and dabbling for vegetation and small fish. Wild turkey and woodcock call from open areas.
Winter is a good time to see woodpeckers and evidence of their presence. Pine Grove Furnace has at least six species of woodpeckers.
Summer is the time of lush green vegetation and growing young animals. In thickets and along roads, watch for spotted fawns and frantic bluebirds searching for food to feed their hungry chicks. Butterflies reach their peak numbers and can be seen floating from flower to flower in the fields and wetlands.
In the fall, the deciduous trees lose their chlorophyll and their leaves reveal beautiful reds, oranges and yellows. This is a time that many animals are preparing for the winter season ahead. There is a growing population of black bears in the area and visitors may see one putting on weight for the winter hibernation. Beavers may be seen working on lodges and dams in the upper channels of Laurel Lake at twilight.
