In the twenty-five years since the Project began, more than 4,000 Simpson Planets have been tossed, dropped, nestled, buried, and otherwise left behind in locations ranging from mountain peaks to ocean depths; in homage to nature, science, culture, and history; in tributes to friends and family; in more than 80 countries and all 50 states. Readers of this book will follow the diverse experiences of "hiders" whose stories and photos are poignant, poetic, and beautiful.
