Some of these sites I've been very close to at one time or another but unable to stop for whatever reason (Devil's Postpile, for example, when I drove to Yosemite from Death Valley and it was just too late in the day).  Some I've never heard of before and had to Google (Crowburg Basin, SC, for example).  Others are places I've always wanted to see but just haven't had the opportunity yet (Checkerboard Mesa in Zion is one).

Here's a few others I'd add off the top of my head...

- Champlain Thrust, Lone Rock Point, Burlington, VT
- Whaleback Anticline, Bear Valley Strip Mine, Shamokin, PA
- Rialto Beach, Olympic Peninsula, WA
- I was much more impressed by Glacier Point in Yosemite rather than El Capitan
- Similarly, Harney Peak in SD is much nicer than Mt Rushmore
- All U.S. National Parks & Monuments (too pedestrian for this list, but all are really must see!)

I'm going out west later this summer, maybe I can hit up a few of these.
