Week 2 - Igneous Rocks

 

One place that I recently when hiking to was Catoctin Mountain in Maryland.  It is a beautiful area that overlooks the Frederick valley.  The rock formations in the Catoctin mountain park were deposited about 500 million years ago as volcanic lava flows.  The pictures are from a rock formation called chimney rock.  In the area the area there are many metamorphic rocks but there is still large deposits of rhyolite and basalt.  Also, many of the sedimentary rocks that have formed have quartz in them which is another igneous rock.  The Catoctin mountains are also famous for another camp that is just north of where chimney rock is.  That camp is Camp David, the presidential retreat.
