The strange beast was first reported by some Mormon emigrants, who observed a peculiar procession entering the desert from a certain mountain range, afterward named the Funeral Mountains. It said that the creature live in little meadows and parks in the higher portions of the range, where it gradually increases in numbers, until by a strange impulse it is seized by a desire to emigrate. Then they go on a disastrous journey across the desert walking in single line. None will ever survive the journey as they cannot take the heat of the sun. Eventually they fall over and explode due to the intense heat and leaving deep, grave-shaped holes in the sand.
