Of Once-Used Imus
This structure is the Imu once used by the Renaissance Resort and now overgrown from disuse.
An Imu is "a Hawaiian "underground oven" used for cooking. Fire is used to heat riverbed rocks which are covered with banana tree stumps to create steam. Food is wrapped with heat resistant banana leaves & Ti leaves then covered with earth and sand. Left to cook underground, temperatures can reach over 450 degrees, and the surrounding area can be extremely hot."
