Figure 12. Bedrock ledge is exposed in the intertidal shoreline of Reid State Park where tidal flow enters and exits the lagoon (Figure 11). When the tide is low the channel is shallow and the bedrock acts as a sill or dam for ebbing water. The view is looking east into the wide and deep Sheepscot Bay. Tidal currents into and out of the lagoon can be observed at any stage of the tide from a bridge in Reid State Park that leads to a parking area at Griffith Head. Photo taken by J. B.
