Sullivan County is a county located in the U.S. state of Pennsylvania. As of 2010, the population is 6,428.[1] Sullivan County was created on March 15, 1847, from part of Lycoming County and named for Charles Sullivan, leader of the Pennsylvania Senate. Its county seat is Laporte[2].


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.[3] 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).[3]

According to the official state publication Pennsylvania Local Government, 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.[4] 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.[5]


According to the U.S. Census Bureau, the county has a total area of 452 square miles (1,172 km²), of which 450 square miles (1,165 km²) is land and 2 square miles (6 km²) (0.53%) is water.

Elevation ranges from 2593 ft at North Mountain in Davidson Township to 779 ft on Loyalsock Creek at the Lycoming County line.

Adjacent countiesEdit


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 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.[6][7]

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. (PA Geologic Survey Map 11). The fields contain either bituminous coal or semi-anthracite, and all occur within Pennsylvanian strata.
