Well - a few pics to give a flavor of ''Indian Caverns PA'' - there is much evidence of their use by Indians a long ways back, tho now more has been opened up to view.
To get really good pics would require studio lighting - here we have direct flash which actually is crap for useful lighting! These pics tho do show some of the fascinating formations, made of course over many 1,000's of years. The last pic shows a formation that understandably has been christened ''Madonna".
