Hayden
Valley - Former Lakebed
Through
pine forest blankets much of the Yellowstone Plateau, Hayden Valley is
treeless grassland. The broad valley floor, low
hills,
and vegetation pattern show the ghost-contours of a former lake.
Fed
by melting glaciers, ancient Lake Yellowstone rose 270 feet during the recent
Ice Age, and an arm of the lake flooded this
area.
The forested ridge across valley marks the former shoreline.
In
Hayden Valley you can see how glacial geology affects wildlife habitat.
As the ice receded, a thick layer of silt accumulated on
the
lake floor. The fine-grained clays and sands favor shrubs and grasses
that support large herds of bison and a variety of other
animals.

area covered by Yellowstone Lake.
