Many small beaches on Salt Spring are swash-aligned pockets, completely contained by bedrock points. Beddis Beach (Gravel Beach 2008), a short distance south of this one, is a great nearby example.
This one off Price Road is not a pocket beach. The shoreline orientation changes and the beach becomes a little more swash-aligned, which allows a wider beach to build, but there's nothing at the distal end to keep it from spilling around the corner. A small stream delta acts like a groin, and there's a small rock groin, too, but these simply the slow the beach down, they don't stop it.The sediment on this beach appears to come from the shoreline to the south - eroding banks and a small stream mouth.
Farther downdrift the beach is coarse and narrow, except where a couple of groins attempt to trap the rapidly moving finer material. Half a mile farther north, where the coastline turns west again, the beach itself just keeps going strait, forming a small spit (a site for a paddle trip in a future year).
AERIAL VIEW (Google Maps)I think one lesson here is that in this highly oblique wave environment (the west shore of Ganges Harbor), the width of the beach (the volume of the beach) is a function of the speed with which sediment passes through - which in turn is a function of the orientation of the beach.
