Nice texture photos, Tradster. I’m guessing that the summit of Mt. Dana might have been a bit hostile during that week – spectacular views at the beginning of day 1, although probably quite temporary views. Thanks for the three more links. I read the abstracts and saved the two PDFs. Sure is nice to be able to store papers in PDF format on a computer, rather than in file boxes full of real paper. Reminds me of a story...

When I was in school at UNR, I was downstairs in the science library one day, photocopying papers from geology journals, and had a mishap. They often bind several journal issues into one binder/book, which makes it difficult to fully open the pages, to get a photocopy of an entire page. So, as we all have done, I was pushing down on the binder to flatten the pages as I was copying, and unfortunately didn’t realize how thin the glass on the photocopy machine was. : ) Well, next thing I know... SMASH!... there goes the glass. Oooops, sh#t, I thought. There was a girl/lady sitting over at a near table, who immediately looked up when she heard the semi-loud noise, with a look of WTF? on her face, but she didn’t say a word. I went upstairs to the front desk, and told the old guy there what had happened, who then had a look of disbelief on his face, but acknowledged that it can be difficult to copy pages when they bind so many issues together. I felt bad about it at the time, but get a good laugh out of it now. : ) LOL...


Mouse, do you see the sharp contact in your second El Cap photo, which can also be seen in your first photo? The right-facing corner in your first photo is the “rivet corner” on Tribal Rite – pitch 3. The topo in the SuperTopo book has this feature drawn more accurately than the topo in the Sloan book. The feature in your second photo obviously needs no explanation.


Fritz, your quartz has parasites! Nice stuff.

Where was that photo of the ash fall olisolith taken? Near Monticello dam?


Minerals: just got a copy of Mike Searle’s book Continents Colliding.
An incredible compilation of work on the geology of the Himalayas & Tibet.
Many of the photos look like they’re out ofAmerican Alpine Journal.

If the weather cooperates, I hope to post some photos of beautiful rock from between Grants & PieTown NM in the next few days.

Crumpled and rumpled, it looks like serpentine, but what do I know? At Bagby-on-Merced.

I did get a couple of shots at the Visitor's Center of shallow marine fossils and worm burrows in what I think is the Lower Permian Glorieta sandstone...
