Day 099: Mill Creek Marsh Low Tide - April 9. Mill Creek Marsh in the New Jersey Meadowlands. The tree stumps are those of centuries old Atlantic Cedar trees. Back when the first settlers arrived and long before, this area was a fresh water swamp with large forested areas of the trees. The trees were cut down by the settlers for roads, homes, roofs and other construction. The trunks were discovered about 20 years ago when this tidal pool was excavated to clear overgrown trees and shrubs etc. that were impeding the tidal flow of water. Now the trunks can be seen at low tide and are a favorite perch of gull, ducks, and egrets.
