Islanders say that General MacArthur bathed at Air Kaca, a cavern on the western side of Mo-ro-tai, shortly after arriving on the island. Some also say that the cavern was created when MacArthur ordered Allied troops to dig a channel under cover of darkness to enable them to slip ashore in secret.
位於摩洛泰西側的 Air Kaca 湖，即是麥克・阿瑟登陸後，闢來取水洗澡之處；另有一說，此湖是當年麥克・阿瑟為登陸島上，命盟軍趁著夜色昏暗鑿建的秘密通道。
