January 31, 1930, the Columbia River froze solid, so solid under the I-5 bridge that Clarence Murray in the early day Vancouver Flier used it as a temporary field for his American Eagle, 90 horse power bi-plane. He is in the photo below on the right. His son Glenn is on the left.
On January 25, 1930 this photo was taken of a leisure drive across the river!
February 1916 shows the river frozen in photo below.
