Remarkably, it seems like this line may not have been climbed until February of 2013. An unusual route for the Eastern Sierra, I wish we had more like it.
Dale Apgar and Mike Collins spied the first two pitches while scrambling up the North Ridge of Mount Morrison across the canyon. Collins climbed the first two pitches, and word got out. Apgar and Ryan Tetz came back a few days later and added a third. Jed Porter and Ian McEleney got caught up in the excitement and climbed it to the top within a week of Collins' ascent. The first two parties thought they were repeating an Andy Selters route called Conviction. Later Apgar confirmed that the Conviction name belongs to some WI3-looking flows just down-canyon.
This route climbs the south shoulder (approx. 10,840) of Laurel Mountain, about a mile south of the true summit. Much of the route follows a couloir that is avalanche terrain. The various descents are also in avalanche terrain. The route generally faces east and parts of it (including the first pitch) receive a lot of sun in the morning. Plan accordingly.
Pitch one climbs nearly 60m of sustained WI4. Where the ice levels off and gives way to snow look for some fixed stoppers (easily backed up) on the right. Belay here.
Follow the couloir up for several hundred feet of low angled snow. You're headed for a smaller, tributary couloir on the left with a runnel of ice.
Climb this for about 35m of WI2. The first ascent parties found the bottom of this to be extremely thin and supplemented the ice with some rock climbing.
Hike up the snow to another, shorter step of mixed climbing that may or may not have some ice dribbled on it. Above this follow snow until it dead-ends into a steep rock headwall. Turn right here and climb a fun pitch of surprisingly steep snow ending on a cool snowy arete. Now head left and climb lower angled snow and a step of chossy rock to the top of the ridge. Unrope and post hole to the top of the south shoulder of Laurel Mountain.
Park at the Convict Lake Marina parking lot, at the outlet of the lake. Follow the trail around the right side of the lake and up into the canyon for a little less than 3 miles. At about 7500 feet the first pitch should be clearly visible. The route starts about 200 feet left of the Mini-Pinner couloir. The approach takes 1 - 2 hours. Some flotation is desirable, but conditions/coverage will often make skiing not worth it.
To descend hike down the Mini-Pinner couloir, or hike south and drop into the canyon where the cliff is shorter.

Trail around the west side of Convict Lake was almost dry and we found a packed snowshoe trail (lucky!) for a good part of the way up Convict Canyon from there. Skis would not have been useful to us. Only had to posthole the last 3/4 mile or so. Hard 2 hour approach would easily be 3 if not for the snowshoe trail. Skis or not, there is no way you'll ever get there in 1 hour.
We climbed on a 70M half rope (doubled over) and split the first long 60M ice pitch into two - this allowed us to carry a few less screws overall as you won't need many for the upper parts of the route. Fixed nut anchor at the top of the WI4 is still in place. The WI2 pitch was thin but excellent. The short mixed step above had ~10 feet of 5th class rock to some more nice WI2. I brought a couple of thin KB's and ended up using them for multiple belays. The rock is a rotten black limestone that doesn't afford many solid anchor options - dig in a snow hole or pound some iron. Beaks also work nicely. The steep snow pitch up to the arete was unconsolidated and a real struggle - mixed rocky terrain to the right made for easier progress. 1 long mixed pitch (M2) from the snow arete led to the base of the final rock band, which is scrappy ~5.7R/X climbing on loose rock. Unless you have really good snow conditions for the sections between the lower technical pitches, expect a Grade IV effort getting up this thing. We wallowed hard. Chose to descend one drainage/gully north of the Mini Pinner couloir - a bit less intimidating to drop into and easy walking all the way down. Our rack - 1x cams 0-3", 8 screws, 1/2 set nuts and a couple thin KB's.
Edit to add: This is real deal choss - much more so than your typical loose Sierra granite ridge. Anchors and protection above the initial ice pitches are mostly mental and bailing from anywhere above P2 would become increasingly more difficult. Jan 5, 2020
