We walked around #Cohasset, #Massachusetts #USA in the unusually warm (50 F, 10 C) “winter” weather here in #NewEngland. This is an (absurdly) prosperous #coastal community just south of #Boston. The walk included lovely views across coves and marshes (including #invasive Phragmites australis and #peat under #native #Spartina), as well as nice exposures of the > 600 Ma #Dedham #granite, the #pluton coring most of the #Avalon terrane in this area.

View of sunlit Phragmites australis seed heads on a marsh edge in this square format color image. Golden, low winter light illuminates the seed head and marsh behind, with woods in the distance and a mostly clear blue sky with just streaks of clouds, blurred by the wide aperture used for this photo. My photo.
A view out onto Cohasset Cove at low tide, in a 2 wide to 1 high color image. A wall and tree in the right foreground are in shadow, above a small tidal creek that flows into the cove. In the near left, over a meter of peat has accumulated in the marsh, covered by spartina. There are buildings, boats, and a barrier island in the distance. My photo.
An eastern red cedar (Juniperus virginiana) grows from a crack in Dedham Granite in this 4 high to 5 wide rectangular crop monochrome image. The crack extends from the low left to bottom right corner, and it is hosting moss along with the tree. The small tree rises through the left center of the frame, with characteristic spiny branches and bristly needles. The Dedham Granite is light gray and coarse in texture. My photo.
Country rock in Dedham Granite. The fine-grained, medium gray rock on the left is probably a chunk of surrounding rock that was plucked into the Dedham pluton (coarse, light gray rock at right) during intrusion. A small tuft of grass is on the right side of this square image. My photo.
