Cottonwood outhouse.

Old outhouse pits are seen as excellent places for archeological and anthropological excavations, offering up a trove of common objects from the past—a veritable inadvertent time capsule—which yields historical insight into the lives of the bygone occupants. This is also called privy digging. It is especially common to find old bottles, which seemingly were secretly stashed or trashed, so their content could be privately imbibed. Fossilised feces (coprolites) yield much information about diet and health. The remains of a thousand year old Viking outhouse were discovered in 2017. This is the oldest known outhouse in the country, even though evidence cannot establish it to be "the first". This discovery was considered to be culturally significant.(Wikipedia) This Outhouse is located at Cottonwood House, BC
