Course
Sinking Creek begins in the Bear Meadows Natural Area in a valley in Harris Township. It flows northeast for a few miles and its valley narrows. The creek eventually enters Potter Township, where it turns northwest before turning northeast again. A short distance later, it passes through Colyer Lake and picks up the tributary Boal Gap Run a short distance afterwards. The creek then begins meandering and crosses U.S. Route 322. Some distance later, it crosses Pennsylvania Route 144 and receives the tributary Potter Run. The course of the creek becomes slightly straighter as it continues northeast on the northern side of a mountain. It eventually enters Gregg Township. A few miles further downstream, it passes north of Egg Hill, and then reaches its confluence with Penns Creek at the community of Spring Mills, 58.82 mi upstream of the mouth of Penns Creek.
