1 • Prior to the last Ice Age, Pine Creek flowed east past Ansonia to the Tioga River.
2 • During the last Ice Age, the Wisconsin Advance completely encased Pine Creek and the surrounding mountains in ice thousands of feet thick, halting its flow.
3 • The glacier began retreating about 15,000 years later. Melting ice carved new drainages as the water found its way south. A lake formed over the original bed of Pine Creek, and overflow waters cut a path through the soft shale between Colton Point and Leonard Harrison State Parks, the beginning of the Pine Creek Gorge.
4 • Glacial till (boulders, rocks, and soil) filled the creek bed as the glacier retreated, blocking flow past Ansonia.
5 • Pine Creek now flows east to Ansonia, then turns abruptly south into the newly formed gorge.
