About 75 million years ago a shallow sea spread across the
Great Plains when the Earth’s climate was warmer than it is now. This sea covered an area from Canada to
the Gulf of Mexico and stretched across the land from western Iowa on the east
through Wyoming on the west. As
the Rocky Mountains rose under the moving Continental plates, the sea retreated
and drained away leaving a sediment layer rich in fossilized animals from the
sea. Now the emerging land
experienced a humid and warm climate with abundant rain and developed a dense
subtropical forest. Millions of
years later as the climate dried and cooled the forest became savannahs and
then the grasslands that they are today.
The ancient soils have collected one of the greatest arrays of fossil
mammals on Earth, most of which are now extinct animals. Some were small and deer-like. Others resembled sheep. There were three toed horses and early
ancestors of modern pigs.
Saber-toothed cats the size of a leopard shared the land with small
Subhyracodon rhinoceros and massive hippopotamus-like animals called
Metamynodon. Squirrel like rodents
lived in the trees and ancestral rabbits nibbled on plants below them.
It has only been for 11,000 years that the land supported
humans. First were ancient mammoth
hunters. Much later nomadic tribes
followed. Their lives were built
around hunting bison whose range extended from the eastern Rockies all the way
to the western Appalachians. Sioux
and later Lakota came to these plains utilizing horses they had acquired from
the Spaniards to dominate the land for 100 years from the mid-1700s. Touching the land gently, they hunted
and harvested only what they needed to support their way of life. Eventually, European trappers,
soldiers, miners, cattle farmers and homesteaders displaced the Lakota by
introducing wheat fields to cover the prairies and practically eradicating the
buffalo to replace them with cattle.
Preserved within the Badlands National Park are nearly 60
species of grass forming what remains of the native grasslands. These grasses evolved to withstand high
winds, long spells of dry weather and frequent fires. Under the protected conditions in the park, black tailed
prairie dogs, muledeer, pronghorn antelope, bison, coyotes and bighorn sheep
once again thrive here. Even one
of the rarest of mammals-the black-footed ferret has found its way back to
recovery here after being reintroduced in 1999.
This has been a marvelous stop in our travels to an area
that is completely new to me. The
colors of the rock and the starkness formed a formidable barrier to the peoples
who came here earning the name “Badlands” but I find them to be anything but
that.
