Nobody else ever done Tightrope? At one point in 1978 my partner and I had done every known free route(and several unknown routes as well!) on the Apron. A couple of days ago I asked him what his favorite route was on the Apron and without hesitation he replied, "Tightrope."

I climbed it with Randy Hamm and he did ALL the leading. I had a cast on my left ankle. Yep. Clean, too.
Can't say the same for the socks I had over the cast.

I've always loved climbing over there. Stacks of great routes for sure.

Conyard, Grack Marginal, Patio, Calf, Goodrich, The Oasis...I used to love the Apron in early days. Funny as my climbing career progressed I spent less and less time over there. When I finally retired, I hadn't been to the Apron in years.

Following up on some of the earlier posts about rockfalls at the Apron (and not to detract from the great climbing content), I think it is interesting to look at the distribution of talus at the base of the Apron. Remember that this talus has all accumulated in the past 15,000 years or so, since the last glacier retreated from Yosemite Valley.
You can clearly see the talus distribution in the image below, which was derived from airborne lidar data and has the vegetation removed. Monday Morning Slab is in the center of the image. It's not entirely clear to me whether the large talus piles on either side of MMS are the product of incremental deposition by small rockfalls or whether they are more a product of a few really large rockfalls, but I prefer the former interpretation based on the morphology of the talus slopes. Based on that interpretation, the observations by Bruce and Karl above appear to be borne out over geologic timescales, i.e. that there is more rockfall to the east and west of MMS. Features like the Punch Bowl have clearly funneled a lot of rockfall debris and would consequently be more "rockfall prone".
Here's another view:
When we measured talus volumes beneath various cliffs in Yosemite Valley and normalized those volumes by the size of the cliff above, we actually found that many cliffs (El Capitan, Cathedrals, Three Brothers) had higher rates of rockfall than Glacier Point over thousand-year timescales. Make of that what you will.

Heck of an image, Greg. Thanks for the explanation and theorizing.

Thanks for sharing this stuff Greg.
Bump for a great place. Some pics from a fun day on Coonyard with Davidji a few years ago:

Greg,
I've always felt like Monday Morning Slab was on the center of a subtle ridge that would divert falling rocks to either side, so it doesn't surprise me to see bigger talus piles on either side of MMS.
And Mouse, do you still see Randy? I haven't seen him since my Berkeley days.

I used to lead Harry Daley with the lead rope tied in a hangman's noose around my neck (instead of attached to my harness).

FStock: "When we measured talus volumes beneath various cliffs in Yosemite Valley and normalized those volumes by the size of the cliff above, we actually found that many cliffs (El Capitan, Cathedrals, Three Brothers)"
When measured by my experience of just 30 years, I've seen more rockfall at El Capitan, Cathedrals, and the Three Brothers than at the Apron and i've hung at the apron a lot. Not as Catestropic at El Capitan and the Cathedrals, but more frequent
Peace

Stunner imagery. Would LOVE to see more if you have other corners of the Valley similarly imaged?

Always seems to be spitting rock over on the west side beneath the Punch Bowl. Heard from Bob Harrington back in 1975 or so that it was pretty active over there. Never had reason not to believe him. I think frequency has a lot to do with whether you'll get hit by rockfall or not. Sure, a big catastrophic rock avalanche will obliterate everything at the base. But all it takes is one good hit to knock your head clean off. And if there are a lot of frequent individual rocks coming down, there's a pretty good chance you'll be a target. That's the way it is over below the Punch Bowl. A big giant avalanche every once in a while. But every day, spit, spit, spit, spit.

Lived in Curry in 70s and did all Apron routes that were up then and put two up ourselves, but never met anyone else that liked the Punch Bowl. Rockfall was an issue but from what I'm reading may have gotten worse. What was funny were the frisbees any trash cans thrown down from G.P.

Tightrope is a good one. Can't believe nobody had mentioned Misty Beethoven or a Mother's Lament, both rites of passage on the Apron.
