Streams often exploit such lines of weakness where the breakage in the rocks makes them easier to erode. Glaciers also often take paths of least resistance moving down preexisting stream valleys. Trout River Pond is really a landlocked fiord cut off from the sea by the same rebounding that elevated the wave-cut terraces in town. Movement along the fault now juxtaposes the lighter colored rocks from the lower part of the ophiolite complex on the north side of the pond with the darker colored rocks from the upper parts of the ophiolite complex on the south side. The rocks from the upper part of the ophiolite complex outcrop on the south side of Trout River Pond.
Sheeted dykes occur near the top of an ophiolite complex where molten rock is intruded into cracks.
As this process is repeated over time a set of vertical, tabular bodies of rock are built. Here you can see one such dyke partially broken away and another behind it. Pillow lavas are the rocks that occur in the topmost part of ophiolite complexes. The rounded shapes of individual pillows result from these rocks being extruded as lava into sea water. These are very old and weathered rocks so the pillows aren't too easy to see.
