[Hide Comment] Day at Arch as climbing Rostrum:
Climb New Dimensions ( in 3pitches) , Anticipation, Leanny Meany, Blotto, Midterm and Gripper(p1 only) in one day and it would be same as climbing Rostrum in term of length and difficulties. Eight pitches - tree -5.11 and five -5.10.
Add English Breakfast and Supplication and it would be like Astroman? Feb 18, 2010

[Hide Comment] Many of those routes are longer and harder for the grade than their respective pitches on the Rostrum. For instance, Anticipation and Leanie Meanie both feel harder to me than anything on the Rostrum. I think any party capable of that circuit would probably hike the Rostrum in under 2 hours.

As far as Astroman, I don't know because I haven't climbed it. But I'm guessing that there's nothing at Arch Rock which could adequately prepare someone for the Harding Slot. Sep 27, 2011

[Hide Comment] The Arch Rock base got moderately torched by the Ferguson Fire this summer. Things are climbable, but the ground at the base is going to be more susceptible to erosion until vegetation reestablishes itself. Thus extra care should be taken to locate and remain on the approach trail.

To find the best approach trail on the way up, head directly uphill through the talus, aiming for a large, lonely pine tree directly below the climbs. Pass this tree on the left and you'll locate the beat out, solid trail just above. Try not get sucked too far right; this will lead you into loose, ashy debris. Oct 16, 2018
