A stone arch acts as a portal through which a forest path passes at Columcile Megalith Park in Bangor, Pennsylvania.  The park was created starting in 1975 by William Cohea Jr and features various arrangements of stones from small, carefully constructed piles you find while hiking through the forest all the way up to massive "menhirs" or free standing single stones weighing as estimated 45 tons.  In areas of the park it's tempting to make comparisons to England's Stonehenge but there is a unique feel to Columcile that I doubt any other place has.  It's well worth the trip to spend a few hours exploring there.  You can get more information on columcille.org.

From a photographic perspective I can sum up Columcile by saying Wynn Bullock would have loved making images there.
