Ice Ages and Weathering: Throughout the district the effects of weathering have had a important impact.
The last Ice Age (10,000 years ago) involved large
masses of ice, miles thick, that moved across New
York. These glaciers scraped away much of the
earth and rock that was once covering the Herkimer
diamond deposits. Then there were rivers, and they
also took rock away from over the top of the
Herkimer diamond deposits, as well as contributing
to heavy weathering in some places. All of this was
necessary in order for man to discover the Herkimer
diamonds at the surface of the Earth.
Rivers and glaciers carved
away the rock that was on
top of the Herkimer deposits.
This then made the deposits
visible to man.
