Granite is a big word in geology. What most of us call plain old granite actually has a more precise name, depending on percentage of mineral constituents.
"Granitoid" rocks come in a nigh endless number of flavors. Too bad Brian Law doesn't post here. Igneous rocks were his thing. I work with sedimentary rocks. So don't ask me to do it.
The rock which I see incorrectly identified, lately, is quartzite, a metamorphosed sandstone.

The granite of Val Bregaglia on the Swiss Italian border is accessible via a Seilbahn from Vicososprano, Switzwerland. It has a broad range of alpine, multi-pitch climbs on excellent granite. You can stay at the Albigna hut where you can get an excellent meal and a bunk to sleep on. This area is only about 10 km away from the trailhead to the Sasc Fura Hut and the Piz Badile.

Wow Tuolumne_tradster that Swiss stuff is fantastic. That peak on the left in the fourth shot is a uniquely striking piece of rock.
I found some quality Granite in Switzerland at Grimsel Pass at a place called Eldorado. It's googleable.

Flip Flop: The peak on the left is the Punta Pioda. The spire next to it is the Ago di Scoiora. They are located in the Bregalia Range near the Piz Badile and the town of Vicosoprano.

On top of that snow-patched hill on the other side of the lake is an area known as "El Frey" and it is one of the premier granite climbing areas in South America.
Close up the rock formations look like this
and this
and that
Here's what it looks like when you're hiking up to do a climb
The routes are short by Yosemite standards: the biggest formations are maybe five to six hundred feet high (around seven pitches for the longest routes). However the granite is generally of excellent quality (as are most of the routes) and the new guide has around 500 existing climbs.

We visited Grimsel Pass briefly this summer. Only time for one route (9 pitches) but that was great fun and I'd love to go back.

Not the same sense that whole pitches might soon exfoliate off, but the area we climbed looked like a bad place to be in a storm -- lots of debris on the upper mountain that could get washed down the slabs.
It was pretty cool climbing all day above that green glacier silt lake, with higher peaks around.

I'm not sure I buy that GSA Today article. It is an interesting idea, but the authors presented NO data regarding fracture density and simply said "TFCs (tabular fracture clusters) are more abundant in certain areas". I would have loved to have seen data regarding their orientation and abundance. They claim that the fractures "probably" exist under the alluvium of Tuolumne Meadows without backing that up with any evidence. The article seemed to be to be a whole lot of arm waving. I'm surprised that it made it into GSAT.

RP3: Figure 3 in the article is a map showing distribution of tabular fracture cluster density. That map is based on the Riley and Tikoff, 2010 paper which has data on fracture spacing, orientation, etc.
Judging from the photo shown in Fig 7a, dude looks like he could be a climber. Hard to find a better place than Tuolumne to do field work on granite fractures.

You want granite? Okay, here's granite.
The smaller chunk on the left is about one-third again bigger than El Cap. The bigger one is about 7.000 ft from base to summit.

What a good thread topic, Ed!.
All below are West Coast of NA or central AK, and don't even include Squamish.

These last three are the same place, but I couldn't control myself.

My issue with figure 3 is that it is not quantitative. What is "high density" and what is "low density"? How were these categories arrived at quantitatively? I guess I need to look at the Riley and Tickoff paper.

Thanks, TT. I am psyched to see it. I saw one of their research group give a talk at GSA this year and it was similarly vague.

RP3: They define TFCs as having a fracture density > 4 fractures per 10 cm in Cathedral Peak granodiorite. This is an arbitrary field description that they came up with. They define Low TFC density as 2 to 5 meter TFC spacing; high TFC density < 2 meter spacing. I sent my email address via the ST tool. Send me an email to that address and I'll send you the paper.
