Really cool stuff.
To classify all of El Cap and put it into a map would be wild.

Early morning (for you west coasters) bump for geology!

This is Roger Putnam, the masterís student who is working with Minerals, Dr. Allen Glazner (UNC Chapel Hill) and Dr. Greg Stock (NPS). I just wanted to make a few contributions to Bryanís spectacular post about the project.

With help from Bryan, Dr. Glazner and Dr. Stock, I have been working on synthesizing the high resolution photography of the SE face with Tom Evans photos and LiDAR data. We are beginning to get a rough map of the whole face that I have posted below. This map is VERY rough and includes many grey areas (places where we cannot see the contacts because of limitations in the quality of imagery available) and other errors. I am just posting it to give everyone an ROUGH idea of what the final product of this study will look like!




I will be in the valley from May 19th through July 8th to try to get this project done. During this time, Iím VERY excited to talk about this project with anyone who is interested and give scale bars to any climbers planning to climb routes for which we do not have any scale photographs yet. The routes that we already have are listed below:

Lurking Fear
Octopussy
Salathe
Shield
Triple Direct
Nose
Mescalito
NA Wall
PO Wall
Tangerine Trip
Zodiac
East Buttress


IF YOU ARE PLANNING ON CLIMBING ANYTHING NOT ON THIS LIST, PLEASE GET IN TOUCH WITH ME! Areas we are particularly interested include NA wall Ė Tangerine Trip and anything east of Zodiac.

We hope that YOU can help contribute to the understanding of the big stone that we love so much!

Thank you so much,

This is such an excellent thread. It is actually so good it has to be somehow made a reference source on Supertopo, like a new tab created for "Geology" or similar. It is very very valuable and after half a century of modern climbing, elucidates what all the variety is about up on El Cap. Up till now we were just staring and enjoying what seemed random, as if it didn't have a story too and was just visual poetry. Amazing thread, thanks so much.

Hi Roger,

We'll be there some time around Mat 8th. Not sure what route we are planning on though. Thinking Mescalito, which you have. But plabns do change... If on something else, I'd love to give a hand.

NICE! Go for it guys. I'm a geology phd student who has done a few el cap routes -- so I'm totally stoked to see what you all find!

Thanks a bunch,

JerryA,

Bryan can correct me if I am wrong (he has done a lot of climbing up there), but according to F. Calkins' 1985 geologic map of Yosemite Valley, Lost Arrow is made primarily of El Capitan granite with some possible Sentinel Granodiorite. However, given our general lack of understanding of what is exposed on the cliffs of Yosemite Valley, it probably is far more complex.

A map of that area is beyond the scope of this project (anyone else want a master's thesis??!). Thank you so much for your interest! PM me!

This is one of the coolest threads in a long time! It's so gneiss, don't take it for granite! (I know, old bad jokes)

Roger,
This is one of the coolest things ever. Vertical jaking of El Cap!! Very near and dear, as I'm about to graduate with a degree in geology. Buried in schoolwork right now, but I'd love to help eventually!

Looks cool.

How about scanning your GSA photo scale to a PDF, so people can just print it out, then fill in the route / belay number for each photo?
Tom could even have a small stack for distribution....
