I neglected to mention this the other, so I hope it's not too late to mention the death of Alma Snell.
I didn't really know her, but I read her book "Grandmother's Grandchild" about her life and especially her upbringing by Pretty Shield.
"Pretty Shield" was Frank Linderman's worthy successor to his classic biography of Plenty Coups. My review of "Grandmother's Grandchild" apparently isn't on line, and I couldn't find it at home. But I remember it as a very worthy successor to both of Linderman's books. Anyone who reads all three has about as readable a history of the Crow Tribe as it is possible to obtain.
