The Story of Knappton Cove by Nancy Bell Anderson (Author), Heather Bell Henry (Editor).   Lured to the Pacific Northwest by the salmon and timber industries, thousands of immigrants passed through the Columbia River Quarantine Station. In 1891 the U.S. mandated the health inspection of vessels at all Ports of Entry. This is one of the stories Knappton Cove tells in it’s 300 years of documented activity. Nancy Bell Anderson compiles the history and combines it with her own memoirs to offer the reader a delightful journey of the tales of the American dreamers that set food on these shores.
