Black Gut (known locally as "The Gut") is a 1.4-mile-long (2.3 km) distributary connecting the Susquehanna River to Hartman Run in York County, Pennsylvania in the United States. It was formerly a southeast flowing branch of the Conewago Creek bifurcation where it had once separated Brunner and Lowe's Island from mainland York County in East Manchester Township, joining the Susquehanna at the village of Saginaw. This delta no longer exists due to expansion of the Brunner Island Steam Electric Station. Another branch, known as the River Gut, ran 0.5 miles (0.80 km) from the gut to the Susquehanna. This branch had separated Brunner and Lowe's Island before it was eventually filled in, joining both islands into one.

The Codorus Navigation Company, based in York in south-central Pennsylvania, was formed in 1829 to make a navigable waterway along Codorus Creek from York, Pennsylvania, to the Susquehanna River, a distance of 11 miles (18 km). Plans called for 3 miles (4.8 km) of canal, 8 miles (12.9 km) of slack-water pools, 10 dams, and 13 locks with an average lift of about 7 feet (2.1 m).The first 3 miles (4.8 km) of the system were finished in 1832, allowing boats named Codorus and Pioneer to run passenger excursions between York and Barnitz's Springs. After the entire system was opened to boats, arks, and rafts in 1833, the first ark to reach York carried 40,000 feet (12,192 m) of lumber and 100 passengers, and later arrivals brought such cargo as stone, coal, and shingles.Plans originally included a second canal from the mouth of Codorus Creek along the Susquehanna to calm water above Chestnut Ripples. This would have made entrance into the Codorus system easier for craft coming down the river, but the extension canal, though started, was never finished. Competition from the York and Maryland Railroad, which connected York to Baltimore by 1838, and the Wrightsville, York and Gettysburg Railroad, which began operations in 1840, put the Codorus canal out of business by about 1850.Codorus Navigation was one of several privately funded canals such as the Union Canal that operated in Pennsylvania during the same era as the Pennsylvania Canal. Though the canal fell into disuse in the middle of the 19th century, parts of its graded towpath, once used by the mules that pulled the boats, are becoming part of a rail trail along Codorus Creek between York and John Rudy County Park. The trail of 5.5 miles (8.9 km), a northern extension of Heritage Rail Trail County Park, will join 42 miles (68 km) of existing trail that begins in Ashland, Maryland, and ends in York. Construction began on the trail extension in 2006.

The Seven Gates of Hell is a modern urban legend regarding locations in York County, Pennsylvania.

Both agree that there are seven gates in a wooded area of Hellam Township, Pennsylvania, and that anyone who passes through all seven goes straight to Hell. The location in question never housed an institution; the aforementioned doctor only constructed one gate, to keep out trespassers. Despite the popularity of this as a tourist destination, the property is privately held; visitors may be charged with trespassing as a result.
