Long Description:
“Though 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.”
