Terrific Fun Photographing a Yellow-bellied Marmot Pup Climbing a Fence!
It looked to me like this Yellow-bellied Marmot pup was doing CrossFit, a move my son who is active in CrossFit tells me is called a "bar muscle up". By then I was laughing so hard that it was hard to maintain focus on the marmot pup while it was hanging there on the fence.
