1. Glacial History Marker
Inscription.  During the last million years, glaciers as high as cumulus clouds crushed across this land at least four different times. Each time, the river changed course through the transformed landscape of ice-scoured rock and piles of sand and gravel that blocked entire valleys. The result is a river that flows through many different aged valleys.

The far distant valley between Portageville and Nunda, was carved by the Genesee River before the beginning of the ice age.

The middle distant valley, where Lee's Landing is located, was initially formed before the last glacial period. It was recaptured by the present river.

The 10,000-year-old canyon below you is one of the most recent detours of the river. It proved to be too rugged and remote for the early logging operations.
 
Erected by Letchworth State Park.
