Nez Perce in Alberta ?
Yes quite a number ( 171 is mentioned and then 290 , not sure which is correct ) made it across the medicine line into Saskatchewan
as the Nez Perce War of 1877 came to an end . Some settled in Alberta near Brocket .
The whole Nez Perce War , the background of it all just makes one shake their head at how the USA managed to treat badly every single tribe they came across .
