Lakes to Locks Passage:
The First Life

 

Natural Forces

Dramatic geological forces built the Lakes to Locks Passage. When the earth was young, the rocks of the Adirondack Mountains to the west lay by a warm seashore. Buried by the first in a series of continental collisions, they have risen to the surface again, com-pressed to a crystalline beauty. Rifting tore the land apart, so the sea returned. Sandy beaches formed golden sandstone. Sea sediments built layers of lime-stone embedded with fossils. Then another collision added New England to North America.

Sheets of ice shaped the contours of the present land-scape. Glaciers a mile thick rounded off mountains and gouged out the Lake George and Champlain valleys. Melting water filled glacial lakes to 500 feet above the present water level before finally finding an outlet to the north. The sea returned for a time until the

 


Discovery of a whale skeleton on the shores of Lake Champlain generated intense interest among local residents and tourists alike. The whale bones proved that the Lake had been a salt sea in the not-so-distant past. Photo courtesy of University of Vermont Geology Department.

earth’s crust rebounded from the weight of ice, leaving a series of connected waterways that form an inland Passage.

Native Peoples

People have only been here since the glaciers melted. Paleolithic hunters moved north with the edge of the glacier twelve thousand years ago, following big game like mastodons and giant beaver. Migrating ducks followed the Passage on their long flights north, providing a bountiful source of food in spring and fall. About a thousand years ago, Woodland people began to grow crops and establish village sites alongside streams and lakes.

By the time European explorers arrived, at the beginning of the 17th century, the native people to the east and west had developed distinct language groups, Algonquin and Iroquois. Both peoples used the Passage as a travel route for trade.
