|Large boulders within Allegany State Park known as Thunder Rocks|
A most interesting place within the Park to visit is a bedrock city named Thunder Rocks (called a city, because the massive boulders are the size of houses arranged slightly apart from each other so that it looks like there are streets running between them). Rock city is a grouping of sedimentary rocks made up of
conglomerate. The conglomerate is made
of coarse sand and white quartzite pebbles.
The rocks sit on the Allegheny Plateau at 2,260 feet above sea
Made up of huge rocks that one can walk amongst or even climb,
is a great place to
learn about geology, although I have heard several different theories about how the rocks
got here. Rock
At first glance, most individuals believe that glaciers brought the rocks to this area. However, geologists have discovered that this small area of
has not been
touched by glaciers, so that is false. New York
Some say that they were moved here from the nearby
by erosion and gravity. Millions of
years ago, this area was covered by a large, shallow sea. The Catskill Mountains
were formed to the east at this time.
Rock city sits on a conglomerate known as the Devonian Salamanca
conglomerate. Conglomerate rock is
individual stones cemented together. The
theory is that conglomerate is being carried downhill by soil creep that has
been going on for thousands of years.
Another explanation is that continental collision formed the elevated
Mountains. Erosion is
uncovering ancient Paleozoic rocks, the youngest of which are Thunder
Rocks. In short, this theory says that
Thunder Rocks are native bedrock and sit where they were deposited as sediments
millions of years ago.
Note: “Allegheny” is how the name of the
and mountains are spelled in . In Pennsylvania it is spelled “Allegany”. New
And finally, there is an Iroquois legend that states that there once was a struggle amongst the guardian spirits of rocks to see who was the strongest. They challenged each other to see who could throw the largest rock to the top of a mountain. The Iroquois tribe close by heard thunderous noises coming from the mountain. Upon investigation they discovered the “thrown” rocks and named them “Thunder Rocks”.
