The Hudson Bay Coast Southeast of Cape Merry at the Mouth of the Churchill River
In the south is the rocky shore of Hudson Bay with fracture and joint zones in the Precambrian bedrock 1. Sand and gravel have been deposited to form beaches in shallow bays (2 and 3). In the case of the western beach, runnels that carry water back to the sea at low tides are obvious 4. Offshore, wave crests can be seen in deeper water 5. As waves approach shallow water they begin to break, indicated by white areas along wave crests 6. Swash (up beach movement of water) and backwash (down beach movement) can be seen at a number of locations 7. It is noticeable that breaking waves are absent where deep water comes up against a headland 8. A light-toned line well out to sea 9 probably represents the advancing tide.
The outskirts of Churchill 10 and an associated road 11 can be seen in the southwest and southeast respectively.
