Geologic History of the Preserve

On the cusp of the fall season, consider the glaciers that were here 25,000 years ago as we talk about geology on a walk to Picnic Point entrance. Meet at Chamberlain Rock, next to Washburn Observatory, 1401 Observatory Drive. Park on the street or at Lot 26. Additional parking is available at Lot 34 or Picnic Point larking lot and walk up.
