To Sill and back.  Sucess!

Easiest way to bag Sill. Lots of snow on the couloir for the end of June, but not difficult climbing. No gear needed.

I'll be back. Bailed from the couloir.

Mt Sill - North Couloir  Sucess!

Very nice route. One of my Sierra favourites.

North Couloir  Sucess!

Made it up with no problem. Stashed our crampons and ice axe at the top of the couloir, summited and then somehow got off route on the descent. ended up scrambling down some tough rock and mud sections, occasionally using some left behind rap ropes. Made the glacier just before dark and managed to walk/slide back to dirt without our crampons. Tons of thanks to the group that rescued our crampons and ice axes, and entirely due to my own apathy they ended up storing them for two years, finally tracking me down and returning them.

North Couloir  Sucess!

Climbed Sill via the North Couloir with my friends Wes and John. Fun 4th class section and amazing views.

July 2010

Descended after climbing the Swiss Arete. Pretty much dry, so we did not bother to rappel, and the fourth class section is fairly short.

It can be difficult to see which way to go on the way down -- this has been the cause of several epics, and at least one death, in 2004.

Also attempted in July 2005, but turned around -- snow was hard in the morning.

One of the best  Sucess!

One of the best routes I've done - it had all the classic elements of moderate mountaineering. The traverse was exciting and worthwhile, once we found it...definitely one of my top ten.

Nice views  Sucess!

Nice view from the top

Wanted it bad.

So much snow and too much vagina in the pants to push up it all.

Thunderbolt to Sill Traverse  Sucess!

Used the L-shaped couloir on our descent from Mount Sill. I opted to scramble down the class 3 rock on the sides for the first part of the descent and then moved onto the snow.

desended  Sucess!

decended this route after climbing the Swiss Arete. the rap was very fun and looks like there's some newer gear there

Easy class 4  Sucess!

Climb Mt Sill on our way to Polemonium Peak. Perfect conditions and the easiest class 4 I have done.

Loved it  Sucess!

The L shaped snow field was pretty much non-existent, just a tiny sliver of snow along the base of the left side of the col and patchy at that. This made for some loose climbing on that part, but the 4th class beyond Apex Peak was solid and a lot of fun.

yup!  Sucess!

Once up the couloir, it was tough. Lots of snow and ice made it tricky to find the clean route up. Spent a lot of time looking from Apex Peak.

North Couloir Date Climbed: July 22, 2006  Sucess!

Great climb up the L Couloir and challenging rock climb from the top of the couloir to the summit ridge if done free solo. The photos on this Route Page do a great job of showing the route.

Scrubbed plans to do Polemonium after Sill due to the hour and menacing clouds. Instead, did a quick run up to Gayley following the ridge directly as opposed to the Yellow Brick Road route.
