First Nations Map Used by Lewis and Clark

I wanted to do a quick post, which is really a glorified reference to this post over at the Map Room Blog about a historically significant map made by a First Nations person named Too Né for Lewis and Clark in 1805. 

I can't find a much better quality image of this map, and it's hard to make out much detail, but I've read that it shows the course of the Missouri river and a number of different first nations. It also shows, in a few places, Lewis and Clark holding council. 

I don't have much to add to this post other than what's on the Map Room Blog. There is something about it though, that bears a very strong resemblance to this map, also drawn by a first nations person about 45 years earlier. It's interesting to consider if it would look different if it were made by a European and if the similarity in style between these two different first-nations maps has to do with a common way of seeing the world.
