Glaciers, seas, and trilobites. View from Jakes Rocks showing the Kinzua Dam,
Kinzua Lake, and Allegheny River at Big Bend. You have to get out of the car and
walk around a little to see this. If you are real observant you might catch it as you
exit the parking lot at Jakes Rocks. Although these hills
definitely look like mountains, they really aren't.

This is called The Allegheny Plateau, which was made pretty much impenetrable to
colonial settlers after the watershed carved out all the steep valleys.  This northern
section was covered by glaciers, which explains why you see huge rocks, some of
them geometric, just lying around--that's where the retreating ice left them. Before
that, in geologic time, this area was completely covered by water. It's not unusual to
find a prefectly preserved fossil of a trilobite or sea shell here, some of them a
million years old or something ridiculous like that. Notice how no one hill stands out
taller than another and you can begin to visualize a plateau here instead of
mountains. Sort of a geological optical illusion. Click on the photo to see how a
growing nation tried to open up this area.
