Postcards From the Edge: Dad's Family Cards 13

Some of these old postcards are really impressive.  This one folds out into multiple cards.  This is part one of this postcard.  There's more.

Dam at Hot Springs, squirrels, and the Pigtail Bridge.

Survivors of the Battle of Little Bighorn (I don't see any obvious 7th Cavalry members) and The Badlands at the bottom.

Here's the center image of a fisherman.
