Long before it was Chandler Park Troop 66 out of Owen Park spent weekends camping there and climbing the big rocks around a rock crusher along the cliff over the river.  We knew the area as Lost City.  When it became Chandler it was a tossup for family outings with Mohawk Park. On one hike along that side of the river we found a marker on the side of a big hill that said "Future site of Keystone Dam". Howard White
