Fisher has thousands of 19th-century redwood forest logging artifacts , including the removable teeth from an old circular saw blade , double iron oxen shoes , old radio batteries , an ebony-handled dinner knife , pulleys , a corner spool that guided cables in Purisima Canyon ( part of the Purisima Creek Redwoods Open Space Preserve ) , photographs , and hundreds of bottles , including an opium bottle . " The bottles help me date the mill sites , " he says . During forest hikes Fisher also found a foot-long twisted and melted piece of metal from the passenger plane BCPA Flight 304 that in 1953 crashed into Kings Mountain in fog with 19 passengers on its way to San Francisco International Airport from Honolulu
