# Sullivan County, Pennsylvania

Sullivan County is a county in the Commonwealth of Pennsylvania. As of the 2020 census, the population was 5,840, making it the second-least populous county in Pennsylvania. Its county seat is Laporte. The county was created on March 15, 1847, from part of Lycoming County and named for Major General John Sullivan. The county is part of the Northeast Pennsylvania region of the state.

## History

The land which became Sullivan County was originally purchased from the Iroquois by the Province of Pennsylvania in 1768, as part of the first Treaty of Fort Stanwix. It was then part of Northumberland County, then became part of Lycoming County when it was formed in 1795. Sullivan County itself was formed from the northeastern part of Lycoming County on March 15, 1847. It was the thirteenth and last county formed at least partly from Lycoming County (and the fifth entirely formed from it).
Sullivan County was named for Pennsylvania state senator Charles C. Sullivan, who "took an active part in procuring passage of the bill" establishing the county. However, according to Frederic A. Godcharles (1933), the county is named for General John Sullivan, who led the Sullivan Expedition against the Iroquois in 1779.

## Geography

According to the U.S. Census Bureau, the county has a total area of 452 square miles (1,170 km$^2$), of which 450 square miles (1,200 km$^2$) is land and 2.6 square miles (6.7 km$^2$) (0.6%) is water.
Elevation ranges from 2593 ft at North Mountain in Davidson Township to 779 ft on Loyalsock Creek at the Lycoming County line. The county is served by Pennsylvania Route 42, Pennsylvania Route 87, Pennsylvania Route 154, Pennsylvania Route 487, and U.S. Route 220. The major rivers in the county are Loyalsock Creek, Little Loyalsock Creek, Muncy Creek, and Fishing Creek. The majority of the land in Sullivan County is forest, but there is some farmland, especially in the northern part of the county. There are numerous river valleys in the southern and western parts of Sullivan County.
Sullivan has a warm-summer humid continental climate (Dfb) and average monthly temperatures in Laporte range from 21.8 °F in January to 67.9 °F in July.

## Geology

Sullivan County lies predominantly within the Appalachian Plateau physiographic province, which is characterized by gently folded and faulted sedimentary rocks of middle to late Paleozoic age. The southern border of the county is approximately at the Allegheny Front, a geological boundary between the Ridge and Valley province and the plateau. (PA Geologic Survey Map 13). The mountains within the county are part of the Endless Mountains.
The stratigraphic record of sedimentary rocks within the county spans from the Devonian Lock Haven Formation (exposed only in Lick Creek valley) to the coal-bearing Pennsylvanian Allegheny Formation. Generally, the Catskill Formation underlies most of the lowlands, and sandstones of the Huntley Mountain, Burgoon, Mauch Chunk, or Pottsville Formations cap the mountains. No igneous or metamorphic rocks exist within the county, other than possible glacial erratics.
Structurally, the bedrock of Sullivan County is gently folded, with the axes of two major anticlines (including the Wilmot Anticline) and two major synclines (Bernice-Mehoopany Syncline and Noxen Syncline) each trending roughly east–west. There are three mapped faults in the Allegheny Formation between the towns of Murray and Ringdale.
Nearly all of Sullivan County was glaciated several times in the past, during the Pleistocene epoch, or "Ice Age." (PA Geologic Survey Map 59). Most of the county is covered by glacial till of Late Wisconsinan age. Late Illinoian Stage deposits may underlie the Late Wisconsinan deposits, and these are exposed in the south central part of the county (roughly western Davidson Township).
The major rivers in Sullivan County are Loyalsock Creek and Muncy Creek. Both flow into the West Branch of the Susquehanna River. Some streams along the eastern border of the county flow into the North Branch of the Susquehanna River. All of Sullivan county is thus within the Chesapeake Bay Watershed.
Several small coal fields exist within Sullivan County. The fields contain either bituminous or semi-anthracite coal, and all occur within Pennsylvanian strata.
Notable geologic features within Sullivan County include some of the following:
* The Haystacks (Huntley Mountain Formation), exposed along Loyalsock Creek south of Dushore, are sandstone mounds of unknown origin
* Ganoga Lake is the state's highest lake at 2265 ft above sea level
* Ricketts Glen State Park, with its many waterfalls
* Worlds End State Park, including an exposure of the Huntley Mountain Formation, and a "rock city" where cross-bedding is visible in the sandstone of the Pottsville Formation
* The Leberfinger Quarry (on Millview Mountain Rd northeast of Forksville), in the Lock Haven Formation where brachiopod fossils, trace fossils, and plant fossils can be observed
* Grand View, located at the southeast corner of the county on a knob of Red Rock Mountain, provides scenic views of the Allegheny Front
* Ticklish Rock, located near Glen Mawr up Rock Run Road, features a rock formation of the Devonian Catskill Formation.
