Answer:
The Corps of Discovery had encountered the Blackfoot tribe on July 1806, in Northern Montana. One of the Blackfoot's traditional cultures was bison hunting. They depended almost entirely on the buffalo and moved wherever the buffalo went. They would use the buffalo for their food, homes, equipment, and clothing.
In 1806, the tribe encountered Lewis and Clark after eight of the Blackfoot warriors had encountered the two first. During that time, Lewis had been explaining the United States’ intent to bring about a comprehensive peace between all the Indian tribes of the west.
Today, the Blackfoot nations are vibrant communities that emphasize traditional culture in education, wellness and healing programs, and in other aspects of daily life.
Many Blackfoot people rely upon ranching and farming, but also operate Indigenous-owned businesses in areas like tourism, and resource extraction and management.
I hope this is good enough for you.
