This is the massive boulder toward the top of the hill. The boulder boasts a great selection of problems from relatively moderate to very hard. Mostly highball. Bring your friends, and have them bring their pads.
Coming in on the regular approach trail, this hill is the high point generally up and left. It is pretty unmistakable when you get there.
Mountain Project's determination of some of the classic, most popular, highest rated routes for Cavalry Boulder:
I saw the chalk on that the other day and it reminded me that I have yet to do that line clean (haven't even tried it in years!). Seems to me like it is a nasty landing to do as a proper boulder problem with that ledge at 1/3rd height. I'll consult some of the old ninjas and see if if all those TR lines up there have names.
I had a good play on this line the other day, felt V3ish, but it could be 4? I'd say Cape Ann 5.11 if it was billed as a rope climb. I added a new bolt for the TR set-up, so it is a) closer to the actual arete and b) at least one of the bolts up there is now shiny again. The arete/ slab at your back from this line is sweet too, 5.8 with arete and 5.10 if you eliminate the edge and just use the little face holds. I have often thought about bolting a few of the lines on the Cavalry due to the sketch factor of their landings (height and padability), but I fear I would be lynched. I do hope to continue replacing/ adding to the aging TR bolts on top if nothing else.
