Margolin, Malcolm and Mariko Conner, editors, Trail Posts: A Literary Exploration of California’s State Parks, Heyday Books, California State Park Foundation, 2014. In a chapter set in Humboldt Redwoods State Park, ornithologist William Leon Dawson describes a northern spotted owl. “His aspect is anything but ferocious—benevolent rather—and he looks for all the world like some patriarchal gnome disturbed at his slumbers, yet not resentful.”
