Day 185 - Ringing Rocks Park

Today is the 4th of July and the wife & I are off from work.  So after cleaning the house, we decided to head over to the Ringing Rocks in Upper Black Eddy, Bucks County, Pa.  Now you may ask, "What are Ringing Rocks?"  this is a boulder field of rocks that have the property of resonating like a bell when struck with a hammer.

So where did this boulders come form?   The boulder fields formed from a group of diabase sills located in the geologic Newark Basin. The sills were formed when mafic magma from the upper mantle injected into the sedimentary basin 200 million years ago (Early Jurassic Period). When the diabase sills were still molten crystals of olivine and pyroxene settled to the bottom of the sill and formed a thin cumulate unit. By the Pleistocene Epoch (most recent Ice Age - 2,588,000 to 11,700 years BP) the sills had been exposed to the surface by crustal uplift and erosion. During the Pleistocene outcrops of the olivine diabase were not buried by the glacial sheets, however they were subjected to severe freezing, or periglacial, conditions. The periglacial environment caused the outcrops to be broken into extensive boulder fields. (Got this from Wikipedia).

Of Course my wife was thinking of how she could
make the rocks ring w/o a hammer.


She did strike up a conversation with a older gentleman and borrowed his hammer.
After she she struck a few of the boulders, we headed down to the falls.  On the way down
we noticed this graffiti covered rock.

Then we made it to the falls.  Not much water was running over the falls, but it still was pretty.

These images I used a Variable ND 10-stop Filter set to Max.

On the top right my wife wanted her  picture taken.
Note that she is very afraid of heights so this was a challenge
for her to sit near the edge to have her picture taken.

For this image I added a B+W 087 IR Filter

Thanks for looking
