Cameron Ensor (pictured) and Nickolas Grim of the Pennsylvania Water Science Center cut through 7+ inch thick ice in order to make a discharge measurement at 01571184 Mountain Creek near Pine Grove Furnace, Pennsylvania on January 3, 2018. This gage is part of the USGS Federal Priority Streamgage Network. The temperature during their visit was -4F.

Chester County, Pennsylvania has always been close-in hinterland of the city of Philadelphia. As the metropolitan area expanded, Chester County became one of the suburban frontiers of Philadelphia, with developed land cover concentrated along transportation corridors that were first railroad lines and later U.S. and state highways, such as U.S.

Snow dapples the banks on Brodhead Creek near Analomink, PA. This stream reach, and reaches on other streams were surveyed as part of a geomorphic dataset to determine channel dimensions and allow new estimates of bankfull discharge and channel dimensions at U.S.

The Susquehanna River appears as a dark line coursing through this scene in southeastern Pennsylvania. The cities of York, Lancaster, and Reading lie among agricultural lands. The State capital, Harrisburg, is positioned against the orange folds in the upper left of the image, along the edge of the Appalachian Mountain Ridge and Valley Province.
