Was at Dry Falls State Park today. View from the visitor's center. This is only a small (western/left-hand) part of the falls. It's a 400 foot (123 m) tall cliff.

This is where the Upper Grand Coulee ends and the Lower Grand Coulee begins.

With a max Ice Age flood, the water would have been 400 ft (123m) deep as it went over the falls. Or in that case, it would have been more of a big ripple...

The sign at the falls is for a low flow flood.

Favorite day of the past week was spent among the basalt columns exposed by the #iceagefloods in eastern Washington state. Waiting for scans from the film lab, so a phone shot will have to suffice. #easternwa #pnw #geology

@OutOnTheMoors I’ve been to this location a couple times, but never realized it could be so humorous. Thanks for the smile! 🙃

Check it out when in Oregon. It’s a great place to tune out for a few minutes and go back in time.
