A day trip out of Seattle up to San Juan Island, near the Canadian border, will take you to one of my favorite Washington icons. At Roche Harbor, a short walk through a wooded cemetery more than a century old will lead to a clearing, in the center of which rests a large stone rotunda. Afterglow Vista (previously known as McMillin Memorial Mausoleum) seems otherworldly—a classical, open-air rotunda containing Masonic symbols, including a round stone table and chairs (in which the ashes of the McMillin family, along with those of John S. McMillin’s secretary Adah Beeny are interred) in the center of a Pacific Northwest island forest.
