Picture of the day
A map drawn based on data collected by
Ferdinand Vandeveer Hayden
during the
Hayden Geological Survey of 1871
, showing the area of the then-proposed
Yellowstone National Park
. The geological survey was the first one funded by the
federal government of the United States
to explore and further document features in the region, and played a prominent role in convincing the
U.S. Congress
to pass the legislation withdrawing this region from
public auction
and creating the country's first
national park
.
