"In 1827, a young Sioux Indian got lost on the prairie in a snow storm, and found his way into a camp of the Sacs. According to Indian customs, although he was an enemy, he was safe while accepting their hospitality. He fell in love with the daughter of the Sac at whose village he had been entertained, and before leaving for his own country, promised to come to the Sac village for her at a certain time during the approaching summer. In July he made his way to the Rock river village, secreting himself in the woods until he met the object of his love, who came out to the field with her mother to assist in hoeing corn. Late in the afternoon her mother left her and went to the village. No sooner had she got out of hearing than he gave a loud whistle, which assured the maiden that he had returned. She continued hoeing leisurely to the end of the row, when her lover came to meet her, and she promised to come to him as soon as she could go to the lodge and get her blanket, and together they would flee to his country. But, unfortunately for the lovers, the girl's two brothers had seen the meeting, and, after procuring their guns, started in pursuit of them. A heavy thunder storm was coming on at the time. The lovers hastened to and took shelter under a cliff of rocks at Black Hawk's Watch Tower. Soon after a loud peal of thunder was heard; the cliff of rocks was shattered into a thousand pieces and the lovers buried beneath, while in full view of her pursuing brothers."
