Interesting #boulders in a roughly stacked #seawall
The southern part of the spit separating #Plymouth Harbor from Plymouth Bay has a seawall along the outer shore, above Plymouth #LongBeach. Without knowing where they came from, interpreting the boulders is sketchy. BUT nice coarse crystals in intrusions into #felsic rocks, including big #quartz chunks (top right photo) and blades of #biotite (bottom right).
