FIG. 34. COLUMBIA RIVER ENTRANCE, SHOWING MOVEMENT OF SAND ISLAND, SURVEYS OF 1851, 1870 AND 1905.
The mouth of the Columbia River in Oregon shows an interesting example of the movement of an island. The chart of 1851 shows the center of Sand Island 314 miles southeast of Cape Disappointment, the chart of 1870 shows it 234 miles southeast, and the chart of 1905 shows it 114 miles easterly. This island has thus moved 2 miles northwesterly directly across the middle of the river entrance, closing up the former north channel. The southern point of the entrance, Clatsop Spit, has built out about the same distance.
