Anthony Henday
In October of 1754 he and his group came to what is now Alberta from York Factory with a mission to meet the Blackfoot and perhaps trade with them. The Blackfoot did not give a clear answer, but Henday decided they meant “no”, so he travelled back to York Factory with news that he had explored the area and had met with the Blackfoot. Since the answer had been unsure, there was no more expeditions to Alberta.
