A chipmunk sits on the stump of an old growth tree in the forgotten mining ghost town of Cody, British Columbia ,September 23, 2011. The stump is one of many left when residents of the town cut down trees to build homes and shops. Cody grew around a silver mining operation that existed from the mid 1890s to 1910 when it was abandoned. British Columbia has one of the largest collection of ghost towns or derelict communities in the country. Many are past mining towns that harvested copper, silver and gold and are either gone without a trace or lie in ruins ravaged by time. Picture taken September 23, 2011.
