Shaped by Erosionand Deposition

Glaciers and New York’s Landscape

Great Lakes – Erie and Ontario Glacially widened and deepened E-W stream

valleys Finger Lakes

Glacially deepened N-S stream valleys Mohawk Valley – “misfit” stream

Glacially widened and deepened E-W stream valley

Glacial Lake Albany – drained when ice left Hudson Valley

Glaciers and New York’s Landscape

Susquehanna Valley modified to U shape

Dammed by till at Wells Bridge (near Otego)

Dam broke and lake drained

Hudson Valley – a fjord Glacially deepened N-S stream valley Flooded when sea level rose Salt water as far north as Poughkeepsie Tides affect river level as far north as

Troy Ocean freighters can sail up to Albany –

Art and the Earth Sciences

Painters of the Hudson River School Mid to late 1800’s Albert Bierstadt Frederick Church Thomas Cole Asher B. Durand Martin Johnson Heade George Inness John F. Kensett Thomas Moran

Kensett’s Hudson - Fjord

Palisades (igneous rock) along the Hudson Fjord

Church’s Niagara Falls – Outwash Channel

Glaciers and New York’s Economy

Thick, fertile soils developed on till and outwash – foundation of agriculture in state

Microclimate associated with Lakes Water moderates climate Warmer in winter, cooler in summer Ideal for growing grapes/producing wine

Aquifers – especially in outwash Sand and gravel for construction
