These are not ducks:
They are little baby grebes (l.) and their ma (r.). Cute, cute, cute.
We camp on this sandbar almost every trip.
But the waterfall runs only when it rains.
A panel of petroglyphs at Anderson Bottom:
It's about 40 feet up a nearly vertical cliff. The mysterious Anasazi probably used a ladder to get up there.
Update: Baby grebes is good eatin'. You don't even have to sneak up on them, just paddle alongside and whap! whap! whap! Dinner! (Serving suggestion: Six on a spit = a perfect fit for the average appetite!)
