The name Iwetemlaykin comes from the Nez Perce place name, pronounced ee-weh-TEMM-lye-kinn, meaning "at the edge of the lake". The park borders the Old Chief Joseph grave and cemetery, one of the 38 sites of the Nez Perce National Historical Park, on land that was once part of the Nez Perce homeland.

The site is open only during daylight hours and camping is not permitted; fires and fireworks are forbidden. Dogs must be kept on leash while bicycles, horses, and off-road vehicles are not allowed to protect the fragile landscape.

The park borders one of the 38 sites of the Nez Perce National Historical Park: the Old Chief Joseph grave and cemetery, just beyond its edge. The name is pronounced ee-weh-TEMM-lye-kinn, a detail many visitors miss when reading the sign at the entrance.
