I attempted to organize a crew to go back there last season and replace the bolts. Unfortunately, we never got a good weather forecast that coincided with everyone's schedules. It will be a gigantic effort to replace 39(ish) bolts on a wall that is at least 7 miles from the trailhead. If you have no prior rebolting experience, then you could still help by carrying equipment back there. I've concluded that the easiest way to do this route is to rebolt in two passes by rappelling the route from the top. First pass to do the anchors, second one to do the lead bolts. Just a two man crew for the actual rebolting is the least problematic.
Of course, nothing ever goes as planned with these things so it will probably require more than two rappels down the wall. More people and hammers on the wall would help, but it becomes a logistical problem if you have too many folks on the wall trying to share anchors. Once the anchors are replaced in the first pass, sending four people down the next time would be less problematic. The other issue here is that you don't want to use up the 10 weekend days per season that this route is actually pleasant to climb on (July-ish). So mid-week is best.
Another issue this year is the huge May snowstorm walloped that zone so the ledges at the top of the route will probably take a good while to melt out to provide easy access to the anchors at the top.
The bolts are all 3/8" and are a mix of rawls and wedges. The holes with rawls should all be able to be reused so long as the bolt does not snap while initially loosening it. The wedges could be a bit more problematic because spinning them is difficult without a power drill. Dan Merrick (I think) has made a handheld bolt spinning tool that could be of use. Since the holes are 3/8", taking the extra time to get it out cleanly will save a HUGE amount of time from having to drill a fresh hole in that bullet hard stone.
I've been in contact with Rossiter and he suggests moving one or two around for better clips/ route/ whatever. I can dig back through the emails to find which ones. He expressed some interest in being up there for input on that.
Igneous (and anyone else who is interested in humping gear back there), send me a message with your email and I'll keep in touch about it. I don't know how much time/ motivation I'll have to try to get that route done this summer, but I can put you in touch with other folks who may be interested in taking care of that this season.
As a final note, if this is not done this season, I know the AAC/AF has a grant for bolt project replacements. It would help tremendously if we could get one of these grants (probably through the BCC) to purchase the hardware for this route. I think it's too late to get it for this season, but if the route doesn't get done this year, it is certainly something to keep in mind for 2018.
Whew, that was a long one. Great job if you read this far.
Cheers,
Dylan
