Loren Rausch leading the last pitch of Panthalassa...


FA 5/20/2012. Four main pitches, one belay move and another really short pitch to get to the tippy top. 5.7, 5.11, 5.9, 5.10, 5.5 (15'). Big pockets. The crux is boulder problem length.
The first pitch is an approach pitch. The belay move pitch (The Cockles Traverse) has even worse rock than the first or the actual summit. The rest of the climb is solid. The summit is very cool, but the last 5-10' of the wall the rock quality seriously deteriorates. There are good bolts on the summit ridge.
See the photo and topo for more info.


To get to the Evolution Fin (we just made that up, if there is already a name for it great: what is it?) take the climbers track left a hundred yards before the Main Area, just before the small rock downclimb in the trail. Keep going sidehill and uphill until the path basically deadends at the base of the climb. There is a large block leaning against the wall just to the left of where the climb starts. See photo and topo.


All bolts and bolted anchors with rappel chains. Pitches 2,3,4 have 11 bolts each and the anchor.
If you top out, don't try to rappel past the anchor 15' down from the summit anchor (horrendous rope drag over the summit choss), instead do a 15' rap, an 85', an 80', a 30', a 90' and a 90'. A 60m rope works great, just be careful. Again, see topo.

Super Fun. A little dirty in spots but hopefully it will clean up as it gets more attention. I would recommend using 3-4 slings on pitch 3 for any future parties, that helped me a lot with rope drag.

Great route with a nice trail. Rock quality is good and will get better with traffic. I definitely recommend biking the approach trail.

Do you enjoy pulling on pockets filled with dirt? Do you enjoy gingerly standing on loose flakes? Do you enjoy watching grapefruit sized knobs come flying off when you pull your rappel ropes? Do you enjoy walking an hour and climbing 4 pitches of choss for 2 good moves? If so, panthalassa may be for you!

Common side effects include: BringAHelmet Syndrome, wishing your belayer was more sheltered, wishing the rock was as solid as the canadian rockies or tetons, and wishing that you had a leaf blower & crowbar along to actually clean the route.
If there wasn't so much loose rock and it wasn't so dirty, this would actually be a halfway decent route; some of the pockets were fun and the crux sequence was intriguing. Unfortunately, it is currently 4 pitches of bolted friable limestone with about ten feet of good climbing (and even there, in the crux sequence, the pockets are dirty).

PG 13 for the amount of loose rock--I have never been so terrified as when I watched another party roll up as we neared the top. Almost impossible to avoid sending a constant stream of pebbles down, punctuated with the periodic baseballs.

TL;DR: Unless there's a herculean cleaning effort, don't waste your time.

Rarely post on mountain project.. However climbed "Panthalassa" today on 4/27/13. Found enjoyable climbing and all good bolts (noticed ~3 that were replaced recently). The stone is not perfect.. but the climbing is good! Future parties may want to bring a brush and do their part to clean up a little dirt and loose rock here and there. The trail is great and easy to follow. I did leave some cord and rap rings on the 2nd pitch's anchor to not interfere with the fixed line (that was tied into the rappel rings). All things that are good!

3rd/4th/nth for the helmet!
A bit chossy here and there, but a fun thin crux and a good adventure altogether.
