Reference excerpt

Greenwood Furnace State Park is a 423-acre (171 ha) Pennsylvania state park in Jackson Township, Huntingdon County, Pennsylvania, in the United States. The park is near the historic iron making center of Greenwood Furnace. The park includes the ghost town of Greenwood that grew up around the ironworks, old roads and charcoal hearths. Greenwood Furnace State Park is adjacent to Rothrock State Forest and on the western edge of an area of Central Pennsylvania known as the Seven Mountains. The park is on Pennsylvania Route 305, 20 miles (32 km) south of State College. Within the park is Greenwood Lake, a 6-acre (2.4 ha) lake that is stocked with trout and which allows ice fishing during the winter. The dam that forms the lake is listed on the National Register of Historic Places. Greenwood Furnace State Park was chosen by the Pennsylvania Department of Conservation and Natural Resources (DCNR) and its Bureau of Parks as one of "25 Must-See Pennsylvania State Parks".

History

Early settlement The northern Huntingdon County area was once inhabited by the Ona Jutta Hage or Juniata tribe. Their name meant "The People of the Standing Stone", an obelisk that once stood in their village near present-day Huntingdon. The Juniata had moved away by the time that Pennsylvania was colonized by William Penn. Penn bought the land from the Iroquois and the Tuscarora and Shawnee that had resettled throughout central Pennsylvania were soon forced to move on once again. Many different groups of European settlers migrated to the area by the late 18th century. They were mostly farmers of Scots-Irish descent with large numbers of Amish and Mennonite Germans who had fled religious persecution in Germany, Austria, and Switzerland. Later settlers built a tavern and a sawmill in the present location of Greenwood Furnace State Park.

Greenwood Iron Works

Greenwood Furnace State Park is named for the iron furnace that was once the center of industry in northern Huntingdon County. Greenwood Furnace was open for operation on June 5, 1834. The parent company, Norris, Rawle and Co., selected the site because of the ease in access to the needed natural resources, iron ore, limestone, trees for charcoal and a steady water supply. Greenwood Furnace was able to produce up to five tons of pig iron ingots per day at the height of its production. Soon a small village sprang up around Greenwood Furnace to support the needs of the workers and the furnace. The village included 20 houses, a company store, company offices, stables and a blacksmith shop. A deposit of high quality iron ore was discovered in the area leading to further growth in the Greenwood Furnace area. A gristmill was constructed in 1842. Greenwood Lake was built at this time to create a water supply to power the mill. Greenwood Lake is currently used as a recreation lake by visitors to Greenwood Furnace State Park. Ownership of Greenwood Furnace Iron Works was transferred to John A. Wright in 1847. Wright was one of the founders of the Pennsylvania Railroad in nearby Altoona. The ironworks at Greenwood and nearby Freedom Iron Works were supervised in part by Andrew Carnegie. Under the leadership of Wright and Carnegie Greenwood and Freedom became vitally important centers of iron production for the booming railroad industry. The company expanded its iron output by building a Bessemer furnace at Freedom Iron Works and building a second stack at Greenwood Furnace. The community surrounding Greenwood Furnace Iron Works reached its zenith in the 1870s. At that time it included the two furnaces, the ironmaster's mansion, a church and school, a company store and blacksmith and wagon shop, there were seventeen stables, ninety tenant houses in the mill village and the gristmill. Greenwood Furnace was the home to about 300 families and included its own baseball team known at the "Energetics" and a fifteen-piece brass band. Greenwood Furnace became a ghost town in the early 20th century. Changes in the iron industry lead to the closing of the now obsolete furnaces. When the furnaces were shut down, the jobs were gone and the people of Greenwood left their homes for jobs elsewhere. The land of the former furnace and village was soon reclaimed for nature through the efforts of the Commonwealth of Pennsylvania.

Tree nursery and state park On February 1, 1906 the state of Pennsylvania purchased the former lands of the ironworks and village from the Logan Iron and Steel Company. The State Forest Reserve Commission established the Greenwood Forest Tree Nursery (which later became the state park) on part of the land, while the rest was made part of the "Greenwood Reserves" and eventually became part of Rothrock State Forest. The soil was ideally suited for use as a tree nursery after the years of use as an iron furnace. The remnants of fly ash and charcoal dust enriched the earth with minerals that were needed for the growing of trees. The nursery began operation in 1906 and closed in 1993. During the 1970s and 1980s the nursery produced an average of three million seedlings per year. The seedlings were replanted in forests throughout Pennsylvania. The Pennsylvania Bureau of Forestry recently re-established the tree nursery on a limited basis to provide seedlings for use at its other nurseries and for sale to private nurseries. The state park was formally established by 1924 by the Pennsylvania Bureau of Forestry (although it was then known as "Greenwood Public Camp"). Former residents of Greenwood village had begun to visit their old homes earlier and in 1921 began an annual reunion known as "Old Home Day." Although the Bureau of Forestry made some improvements to the park, most of the facilities at the park were built during the Great Depression by the young men of the Civilian Conservation Corps, established by President Franklin D. Roosevelt. The boys of the CCC worked to restore a furnace stack and also repaired six original buildings that had not been dismantled when the village was abandoned. In the 1930s the name became "Greenwood Furnace State Forest Park". Greenwood Furnace State Park became an official part of the Pennsylvania state park system in 1966. Archaeological work began at the park in 1976 to uncover the remains of the village. Greenwood Furnace was designated a Historical Landmark in 1995 by ASM International in recognition of the superior quality iron that was produced by Greenwood Iron and was vitally important to the westward expansion of the railroads.

Worked examples

Example 1 — a first encounter with Greenwood Furnace State Park

Start with the simplest possible case. Write down what Greenwood Furnace State Park claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Greenwood Furnace State Park before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Greenwood Furnace State Park ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Greenwood Furnace State Park

In research
Greenwood Furnace State Park appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Greenwood Furnace State Park in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Greenwood Furnace State Park is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1924 establishments in Pennsylvania, Archaeological sites on the National Register of Historic Places in Pennsylvania, Civilian Conservation Corps in Pennsylvania, so understanding it makes those chapters shorter.
In everyday life
Look for Greenwood Furnace State Park outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
