In that place and at that time, girls and boys were separated in terms of what they did. Clearly boys did athletic feats and girls did silly things.
The back of this photo says in May's handwriting, "This was tken in 1920. It is Rose Henderson and I down on the river near here. Don't you think it's a dignified pose." She was thirteen years old. My father's note says, "May and Rose Henderson find a contented cow.
The back says "May Strachan and Rose Henderson on Roaring River Bridge."
The back of this one says "April 1920, May Strachan and Rose Henderson." The album says, "Rub-a-dub-dub, Two girls in a tub." Not quite accurate since there are two tubs.
This one says "May Strachan and Rose Henderson on West Favel river flat." I assume that's what we would call a "flood plain," where the regular overflowing of the river deposits silts and washes away hillocks. The album says "Jack the Airdale leaps and leaves only his shadow." The dog belonged to the Hendersons. Airedales are supposed to be good bear dogs, but I don't know whether that's why they kept one. There probably were black bears around. (Airedale is more conventionally spelled with two e's.)
The back says "May Strachan and Rose Henderson at C. Henderson Farm. The album says, "Jack is more contented here."
The back of this one also says "May Strachan and Rose Henderson at C. Henderson Farm. The album says, "Jack turns his back while the girls play with Billy." Billy is an angora goat. A sheep's head on the left edge.
The Hendersons and the Strachans may have been friends in South Dakota. Certainly the Hendersons were the link to Swan River and helped the Strachans migrate up there to resettle.
