Went up to churchbowl today (wed. april 4th)and there were tons of manzanita bushes at the base of the Bishop's Terrace. To the climber's right there was about a hundred feet of destruction (rock, dust, busted ass trees). Loose pebbles and even a tree branch fell while we were looking around the area. We decided it looked a little to recent and too active for us to risk doing a climb we had done many times before. Just a heads up. From curry village, we had heard a rock fall last night at about 11pm, it could have been the same one, I don't know. If anyone is heading out that way to climb, be safe.

I guess this is specific. I if I remember correctly the rap off is on the climbers right of Bishops Terrace.

Be advised:

Two rockfalls originated from a source area almost directly above Bishop's Terrace on the 3rd and 4th of April. Both occurred at night, with the first occurring at about 11:15 pm on April 3rd and the second at 10:35 pm on April 4th.

From the source area, falling rocks were steered by a series of southeast-dipping ramps just to the west (climber's right) of Bishop's Balcony. The short second pitch of Bishop's Terrace leading to the base of the Balcony was hit hard by rock debris. Some rocks went over the first pitch of Bishop's Terrace, though there weren't obvious impacts. The rappel route from the top of the first pitch was hit hard, with the big oak tree there losing several limbs.

At the base, there is a lot (hundred of tons) of fresh rock debris scattered over an area about 300 feet across, extending eastward from the base of Bishop's Terrace. Small rocks were falling every few minutes when we were in this area.

The source area can be clearly seen from Ahwahnee Meadow. Although I'm not able to predict future behavior, I have seen cleaner source areas than this one. Future rockfalls are possible.

Bottom line: These were relatively large rockfalls that impacted the Bishop's Terrace area hard. It's very lucky that they occurred at night. For now I strongly advise against climbing Bishop's Terrace or any routes on the eastern side of Church Bowl. Routes farther to the west near Church Bowl lieback were not affected. Please help to spread the word.

Hello folks,
Greg and I just returned from surveying the rockfall damage at Church Bowl (Bishop's Terrace) area.

Although there is always a possibility of rock fall on Yosemite's crags, domes, and walls. We feel there is an elevated level of risk for rock fall over Bishop's Terrace over the next week or so. Therefore we have temporarily closed all routes at Church Bowl East of, but not icluding, "Church Bowl Tree".

Let us know if you have any questions,

Thanks,

Looks like a lot of dirt behind where the rocks let go. There are some really big trees right over the release area.

Perhaps this was more a case of trees/ roots prying the rock away from the face than freeze/thaw or internal rock stresses? Or both, but the cracks were invaded and made wider by root growth?

Who wants to inspect the release area to give us more info? :)

Thanks Greg for the usual detailed rockfall info, right down to explaining the flight path. It does appear to have been the worst bit of the general release zone; in healyje's markup of the photo, you can see a lot of water streaks right below the facets that are still covered with dirt, where a lot of the rock probably came from. The other not so happy part doesn't look quite as bad; not that I'd go climbing there for a while, just sayin.

That tree at the bottom of the rappel had a few too many damn branches anyway, good to get some of those cleared out of there.

Thanks, Greg and Jesse. I particularly like the way Jesse phrased this -- there is a risk of rockfall everywhere, but this area's risk exceeds that of most other areas, at least for now.

The more rockfall I've observed over the decades in the Valley, the more grateful I become that none of it landed on me!

Thanks! Finally I found someone who understands *XOXO*

I was not planning to climb there this weekend, I do value my life.

The whole "Bishop's terrace is closed" thing just sounded kind of funny to me. I usually hike/climb peaks and see rock fall often. The idea of a route being closed for climbing by 'the man' leads my thoughts to "this ride is closed" sign somewhere in Disney land...It is just weird for someone who is not used to anything being controlled anywhere. I bet not many can share my humor, but calling someone an idiot is quite disrespectful, we can live without insults. If someone wants to insult me please email me so we can meet, and do it to my face. I do not want to be a part of interpersonal online circus.

I climbed Bishop Terrace 9 years ago and wondered when (hopefully not on my ascent) a big chunk of rock would break loose. Bound to happen.

Yosemite Valley is the rockfall capital of the western Sierra; no other canyon comes close (more, however, occurs on the east cliffs of the High Sierra crest). Only Lovers Leap, a set of cliffs, spalls rockfall at a faster rate than does Yosemite.

Can't blame global warming on this situation.

So the thing about the blocks circled in the photos above is that they were not directly undermined by these recent rockfalls, i.e., they have been that way for probably centuries or longer and we have been climbing under them all that time. Welcome to Yosemite.

Everyone raves about BT and I'm not sure why. The climbing seemed un-inspiring to me. All that to get to ~12' of good hands climbing??

Saw some all brand new gear guy who had been spraying like a sprinkler bail off it after we rapped which made it worth it though. I'm usually supportive of all climbers at all abilities, but watching that guy bail with his date/girlfriend watching, after all that spewing was entertaining.

Oh the rockfall, uh yeah, right. Crazy. Glad it happened at night.

1. Because it's a nice clean aesthetic line.
2. Because it has a 2 minute approach.
3. Because it has an easy descent.
4. Because there isn't too much else in the Valley that fulfills 1-3 and that is also within the ability of the 5.8 leader.

"Everybody" raves about routes that are easy to get to because almost everybody only climbs routes that are easy to get to.

And everybody who does what "everybody" else does almost always agrees with "everybody".


A longish approach adds a star in my book, and regular waiting lines take one away.

Heh. I was thinking the same thing about the length of good hands climbing. I like Ejesta and the Nurdle much more at the same grade.

Ejesta is an especially fond memory for me because I had a lovely, half-clad dream of a thing following me on it. Too bad her boyfriend showed up at the base of the climb :(.

Maybe Yosemite can borrow techniques from Snowbird Ski Resort



Probably something more appropriate for the evil parallel universe where Yosemite is privately owned & run as a rock climbing park by Dick Bass ;-)

When I taught skiing there I heard from the ski patrol that for some of their avvy control runs they'd just toss the explosives from the aerial tram on the way up. I wonder if they were jerking my leg on that one . . .

Val,

I imagine this area is being formally closed not just due to the rockfall, but the overall risk? i.e. how close it is to many unaware tourists & casual climbers who might be unaware of the hazard while hangfire is still likely to come down?

Just curious, but did YNP close the death slabs approach for a period after this little rockfall?

Hi all,

We have been monitoring the rock-fall source area above Church Bowl, and there do not appear to have been any new rock falls following the intial two events (the rock fall reported on April 11 seems to have originated from another location). Furthermore, a recent substantial winter storm with rain and snow, followed by warm temperatures, has so far failed to trigger any addditional rock falls. During my recent visit to the impact area there was no more small debris falling.

This suggests that the rock-fall source area is relatively stable and that the level of hazard posed is similar to "background", i.e., the hazard level that always exists below cliffs in Yosemite Valley. As a result, the temporary closure of the Bishop's Terrace area has been lifted.

Please - please - note that this does not mean that future rock falls are not possible. Although we are actively researching rock falls, predicting them is extremely challenging at this time. There will always be some degree of rock-fall related risk, and this is particularly true for climbers who frequent cliffs and talus slopes. The National Park Service strives to take reasonable measures to ensure public safety but cannot guarantee a risk-free environment in a dynamic natural setting such as Yosemite Valley. I will do my best to provide up-to-date information on rock falls and rock-fall related hazards as they affect climbers, but ultimately individual judgement and discretion is required.

Thanks and safe climbing!
