Looking at Zoltan's meandering channels took me back to my first class in geomorphology, and I've had images of area:slope ratios, shear stress, the law of the wall, and ::shudder:: Reynolds numbers (OK, the equations, not the images) running through my head for the last few days.
While scanning around, looking for potential sites that might present enough of a challenge for the brilliant members of this community I came across this NW-SE drainage. The beauty of the image, the sharp angles of the hills and the broad curves of the channels, just blows me away (notice that there's even a lovely little stream capture at the center of the image).
I had a natural history teacher once tell me that the more I understood the details of the natural world the less I would notice its beauty. I knew he was full of shit at the time and every time I go into the field I'm reminded again how incredibly wrong he was. And other geologists I meet seem to have the same sense of the numinous when looking at landscapes.
So without further ado I present you with WOGE #59:
All the usual boilerplate, including the Schott Rule, are hereby invoked. Winners will have their names carved in the digital plaque and have the honor of hosting #60. Post time is 10:45 PDT.
Cheers...
Update (10/9): These rocks were deposited in a large inland sea and contain both ammonites and inoceramus...

Mancos!
Full explanation to follow...
Nice work Ron. I was beginning to think that the site was too generic...
These badlands, and the adjacent Fremont River, provided fodder for 2 dissertations, one on channel erosion into bedrock (Greg Hancock, now at William and Mary) and one on exposure dating of river terraces (myself)...
If anyone is planning a field trip out west, I can't recommend the country around Capitol Reef enough.
So if one wanted to find the next WOGE, it will be on Ron's page? :)
Newbie, but looks fun!
John--
Yes, keep an eye on Ron's blog.
Sorry for the slow turnaround. I'm writing up a pair of posts right now: first an analysis of how I solved #59, and then WoGE#60. They should be up in an hour or two.
Okay. Here's my analysis of solving WoGE #59 and brand new WoGE #60. Again, sorry for the delays.
