A group of Utes were camping on the shores of Grand Lake when they were suddenly attacked by an enemy tribe of the Arapaho (and in some versions the Cheyenne as well). As the brave Ute warriors began fighting, the women and children were hurried onto a large raft for safety and pushed to the middle of the lake. As the battle continued, a treacherous wind overturned the raft and all the women and children were drowned. Many Ute warriors were also killed during the fighting.
The legend holds that you can still see ghostly forms in the morning mist rising from the lake and hear the wailing of the lost women and children beneath the winter ice. The Utes avoided the lake for many years because of these tragic events and evil spirits.
