Lewis A Swyer Preserve is a small nature preserve in Columbia county that features a boardwalk trail through a freshwater tidal swamp.  Mill Creek, which feeds into the Hudson River is subject to 4' tides.   Unfortunately, heavy rains and flooding last week damaged the boardwalk and coated much of the emerging plant life along the creek's banks and near the trail with mud.  The best photo location turned out to be along the 1/4 mile walk along the road from the parking area to the Preserve entrance.
