Here’s what Buffalo Bill Cody said in his autobiography:
“AN INTERESTING INDIAN TRADITION
While we were in the sand hills, scouting the Niobrara country, the Pawnee Indians brought into camp, one night, some very large bones, one of which a surgeon of the expedition pronounced to be the thigh bone of a human being. The Indians claimed that the bones they had found were those of a person belonging to a race of people who a long time ago lived in this country: That there was once a race of men on the earth whose size was about three times that of an ordinary man, and they were so swift and powerful that they could run alongside of a buffalo, and taking the animal in one arm could tear off a leg and eat the meat as they walked. These giants denied the existence of a Great Spirit, and when they heard the thunder or saw the lightning they laughed at it and said they were greater than either. This so displeased the Great Spirit that he caused a great rain storm to come, and the water kept rising higher and higher so that it drove those proud and conceited giants from the low grounds to the hills, and thence to the mountains, but at last even the mountain tops were submerged, and then those mamnoth men were all drowned. After the flood had subsided, the Great Spirit came to the conclusion that he had made man too large and powerful, and that he would therefore correct the mistake by creating a race of men of smaller size and less strength. This is the reason, say the Indians, that modern men are small and not like the giants of old, and they claim that this story is a matter of Indian history, which has been handed down among them from time immemorial.”

Chapter 15
Sounds like the giants of the bible. The nephilim.
Interesting. Sounds like a story I’ve heard too. In Sunday School. (Although the Sunday School version doesn’t focus on the giants - but they are talked about pre-flood, but not later).
