[SCDAs] Soundless chemical demolition agents
Break granite stone with special cement additive that swells and exerts expansive.
Motorized Drill will work just slower 8-10 min.
Hole Diameter: 38mm - 50mm (1 ½” – 2.0”)
Hole Spacing: 30cm – 60cm (1ft – 2ft) apart. 1 ft smaller chunks.
One on each side , two/three in the front. Hilti will work for drill as well as the bit. Depth maybe foot for each.
Fill holes with expansive cement. Depending if you want it to break in an 10 minutes, hour or four hours up to the design. Less impact on bottom being that they would be smaller rocks. Could also control how much to cut loose. 1/4th,1/3rd, wait, drill more, pour and do it a little at a time.
Further examination and securing of block to see for vibration.
Picture is concrete but works on granite as well.

To follow the mission of the NPS I would just cut the slings off and let it fall when it is going to fall. Why should we be stepping in the way of nature, do we think we own it? If we think we can protect ourselves from this piece of nature, then we are all just delusional. There are loose blocks scattered all over El Cap that could fall at any given moment and unexpectedly squash someone at the base. Where do we draw the line? This is not Disneyland or a padded world. Take the slings off and see what happens. It will go when it wants to. I would be disgusted if NPS spends a ton of money to push that thing off. We are already playing God enough with the Peregrines and Frogs (I don't have anything against either), so why don't we let nature take over and take over the job how it wants to. Sure it could kill someone, yet isn't that how nature works?

I agree that neither climbing in general, nor Yosemite specifically, needs to be any further Disneyfied, but this block has been tied off, so there is no longer any kind of "letting nature take it's course." Cutting the slings is trundling--a human action--and it should be done with due regard to the humans below who might be climbing Sacherer Crack, etc.

It's still there -- seemingly ready to fall and kill everything below it.
I think someone might actually have added a sling.
I tried to contact the climbing ranger Jesse twice, volunteering to go up and give a try and trundling it myself while the area below is cleared, but got no response.
(Maybe my mails are routed straight to his junk folder.)

Drill 3 bolts into it and have YOSAR remove it.
Good training, and removal of a safety hazard.

Stein,
Climbing Ranger Jesse has been responsive the couple of times I've contacted him about safety issues.
If you've been trying to reach him the past few days, he's on El Cap.
Or maybe he's tired of hearing about this block.

Do you really need permission? This is not the Park Service's responsibility, nor should it be. Just think where that line of reasoning leads.
Someone should just cut it loose. In a responsible way, of course, with a ground crew and spotters to make sure no one gets hit.
Make sure to have a film crew as well . . .

From the first picture it looks like it is totally haging on the slings.

Anyone know what's the status on this infamous block?
NPS climbing rangers ever arrange a trundle? Still there?

Wow, JakeW's post is a good reminder that photos can mislead. I'd seen that pic as "evidence" that the block was hanging in space...

don't drill it, don't fill it with expansive clay. don't tag it and register it as historic tat that be holding it steady.
clear the base and let 'er down into that last, shortest phase of a rock's life, the disambiguation and transfiguration of hillslope and streambottom, that sweet surrender of colluvium and alluvium.
that's my vote, see.

I climbed all over that thing this spring. Take it out and manufacture more safety on El Cap. Who wants climbing to be dangerous?
