Falls of the Ohio State Park (page3)
The excitement
of discovery pervades the atmosphere at the Falls of the Ohio.
While park rules prohibit fossil collecting, staff encourages
everyone to search for, hold, and even pass around the loose
fossils they find among the rock outcrops. When the limestone
bedrock erodes away through natural weathering processes,
it can release the harder, silicon-based fossils from the
confines of their stone matrix. Therefore, some fossils actually
drop out of the bedrock.
Once you've
had enough of fossil hunting, you'll enjoy a variety of other
attractions at the Falls of the Ohio. For instance, biologists
have recorded 265 species of birds at the park. Large numbers
of herons, egrets, migratory waterfowl, osprey, peregrine
falcons and occassionally bald eagles visit the area to feed
on the fish and algae found in the potholes and aquatic feeding
areas.
Speaking
of fish, more than 125 species of fish appear in the Ohio
River at the Falls. Several of these, including the paddlefish
or spoonbill catfish, shovel-nosed sturgeon, and the long-nose
gar, are descendant from the age of dinosaurs. The rushing
water, limestone beds, and gravel bars provide feeding and
spawning areas unlike any other on the 981 miles of the Ohio
River.
Although
the name seems to imply waterfalls at this new state park,
in actuality, the Falls are cascading rapids, or cataract
falls. They cause the Ohio River to drop 26 feet in elevation
over a two-and-a-half-mile stretch. Early explorers found
this area the only navigational barrier on the entire Ohio
River - historic records refer to the "Rapids" or "Falls"
of the Ohio River.
Many visitors,
some famous, have graced the Falls throughout the past 200
years. After General George Rogers Clark returned here from
conquering the Northwest Territories during the Revolutionary
War, John James Audubon arrived to render more than 200 sketches
of birds in the Falls area. Mark Twain endured the Falls and
recorded, "We reached Louisville - at least the neighborhood
of it. We stuck hard and fast on the rocks in the middle of
the river, and lay there four days."
After
experiencing a boat trip down the Falls, Walt Whitman wrote
that "The bottom of the boat grated harshly more than once
on the stones beneath, and the pilots showed plainly that
they did not feel altogether as calm as a summer morning.
