There are some great examples of this in the Pacific Northwest.

Here is a good link:

Thanks.

I hear that , from the air, one can see huge sand deposits in forms of ripples made by the river currents.

Up close, these repeating hills are not so obvious ?

That’s a great link. I have often wondered in which order these areas were created. Fascinating.

Amazing place, Dry Falls. We go to Sun Lakes camping every summer. You can see one of the lakes in the picture taken from the Dry Falls Interpretive Center. Already looking forward to next year.

Thanks for the link. Even though I grew up in the Willamette Valley and lived there for 28 years, I never realized that the floods even inundated that large valley.

Perhaps the floods were largely responsible for the deep alluvial deposits? I’ve never understood how the Willamette River and tributaries, primarily the MacKenzie and Santiam, could have put down so much.
