Some heritage of the California Gold Rush came full circle a couple of weeks ago in a downtown Vancouver cemetery.A group of history buffs cleaned up the Old City Cemetery and added holiday touches to graves. As local organizer Eric Klein explained, the volunteers are associated with the Ancient and Honorable Order of E Clampus Vitus.The Clampers, as they call themselves, have a 170-year lineage rooted in America’s mining heritage. A major chapter of that history is the 1849 Gold Rush, sparked by the discovery of gold at Sutter’s Mill.Vancouver’s role? John Sutter’s route from Missouri to California came through Fort Vancouver. That’s not exactly a straight path, and it got even more meandering when Sutter continued to California by way of Hawaii and Alaska.The thread running through that rambling itinerary was the Hudson’s Bay Company. Back then, the British fur-trading enterprise “was probably the largest Euro-American colonial entity on the West Coast, from San Francisco to the Gulf of Alaska,” said Bob Cromwell, acting chief ranger at Fort Vancouver National Historic Site.Dreaming of an agricultural empire in the West, Sutter joined a group of trappers headed for the Pacific Coast in April 1838. He reached Fort Vancouver in October. A Hudson’s Bay ship took him to Honolulu, and then he sailed to Alaska. He finally arrived at Yerba Buena (now San Francisco) in July 1839.
