Sanitation and Water
Outhouses on North Manitou Island are present only in the village and the Village Campground. In the backcountry, use a small hand trowel to dig a cathole, which is a pit for human feces. Catholes must be at least 100 feet away from trails, campsites and buildings, 300 feet from water, and 6-8 inches deep. When finished, cover the hole with dirt and other natural materials to disguise the cathole. Groups should establish a communal privy and cover it after the last use.
Toilet paper should be used sparingly, and must be either buried deep in a cathole or packed out. Place toilet paper in a sealable plastic bag to pack out.
Used feminine items must be packed out.
Urine has little impact on the environment or human health. Diluting urine with water can decrease impacts.
