Big Grunt starts at the bottom of the obvious split in this large boulder (foreground) which sits atop Lunch Rock. A squeeze chimney start leads you to easier chimneying and eventually to the top.

If you ever listen to someone start this problem you'll understand why it has it's name. Those with large pectoral muscles are at a disadvantage. This is a fairly safe route to third class with a downclimb off the backside.

Are there bolts at the top?

If not, what type of gear would one need to set top rope?

Peter, there are bolts and links (was there last night,) but it might be an awkward TR. Not sure, probably belay from above would be best as well.

Amazing classic! Starts as overhung offwidth to squeeze chimney and gets wider as you go up to chimney then turns to a weird slab chimney combo once you hit the hard angle at the top. Loved every second of it. We did it first try and as a free solo. On-site is doable but it's good to know some beta for safety reasons near the top. No rope necessary for me and my offwidthing crew. Although we didn't personally see a need for a rope, I wouldn't advise noobs to jump inside a 30+ ft chimney without a TR since the chance of serious injury is inevitable if you slip once inside or can't hang in the wide. Fairly difficult start for climbers who don't know good offwidth technique. Knowing how to take a rest in a decent froggy leg with butt to ankle jam is super helpful. When you get to the top, don't traverse too far right over the wide gap before you step over to top out. There's a small dark knobby crimp you can grab on to help pull yourself over. "Downclimb" is in the back. Hang down off a square left hand crimp to lower yourself onto a pile of wobbly stacked rocks. Don't just drop down. They aren't that stable. It's best to have someone down there stabilizing the downclimb "stairs" and spotting your descent. Happy grunting!

In my opinion probably the best climb at Mt Woodson.

There is a descent (let yourself drop down onto a pile of rocks), and a down-climb (down-climb the giant crack, near the back). To me, that down-climb is a pleasure that is not to be missed.
