Ice necklaces at Williamsburg Pond

Never seen anything like this before.  Ice beads frozen like a necklace on silver maple trees at Williamsburg Pond.  This pond is connected to the Wabash River when it floods.  The top of the beads must be a remnant of high water during the last flood and temperatures below freezing.  Then as the flood receded rainwater flowing down the tree must have frozen to form these beads.
