Bad Luck, Hot Rocks: Conscience Letters and Photographs from the Petrified Forest - Ryan Thompson - Bog

The Petrified Forest National Park in Northeast Arizona protects one of the largest deposits of petrified wood in the world. Despite stern warnings, visitors remove several tons of petrified wood from the park each year, often returning these rocks by mail (sometimes years later), accompanied by a "conscience letter." These letters often include stories of misfortune attributed directly to their theft: car troubles, cats with cancer, deaths of family members, etc. Some writers hope that by returning these stolen rocks, good fortune will return to their lives, while others simply apologize or ask forgiveness.
