Triumphant after descending. Route starts just out of the left side of the frame and wanders right around the horizontal vein.

Took a breather on pitch 4, the view is amazing!

Anchor locations are approximate. Pitch 2 is really long, more than 16 draws. bring 20.

Heading up the second pitch with our boys, 4 and 7 at the time, climbing as a party of 4 on doubles.

Looking up the crux (5.8) Pitch 4 of Sinocranium.

Pitch 4 of Sinocranium goes up the steep section. It is the crux (5.8) of the route.

Should you see these crazies climbing, run the other way!!

Setting up the Rappel. I took this picture of my friend while I was standing on the very top of the summit. Walking down to this rap station is very easy. The second set of chains are on the right side of the gully as you face the wall.

View of pitch one from the base of the route. Climber is at pitch one anchors.

Looking down Pitch 2 of Sinocranium. The climbing on this route is similar to Theatre of Shadows, but seems a bit harder and the bolts just a tad more spread out (although still comfortingly plentiful).

Looking down from the top of the crux (5.8) Pitch 4 of Sinocranium. We belayed right below it, although there is also a set of anchors about 50 feet before the belayer in the photo.

Steinfells Dome from parking area; Sinocranium is on the right hand side of the big dome.

Start of Sinocranium-NOTE: Large cairn.

The 5.8+ pitch

Dalon and Sheri successful at the summit!

Brian leading the crux pitch that is WAY protected but fun, unique positions.

Sher-bear climbing the crux "fun" pitch!

View of the parking area from top of Sinocranium, long way down!

Climbers on the crux (5.8) Pitch 4 of Sinocranium.

At the top - 7th pitch is a doozy, no bolts, just walk up

Belay stance on top of the hard pitch. Wake up early to avoid the crowds on this route!

A historic shot! Has to be 2010- top of Sinocranium! First trip to the City with Jorden :)

The rest of the bunch coming up pitch 3 on Sinocranium!

View from pitch 3 looking out towards Castle Rock

It's a big rock! if you look carefully, you can see people at the top and on pitch 3 :)

A double rope rappel.

Enjoying the fun crux pitch.

Fun climbing on the crux pitch of Sinocranium. September 2008.

looking up at 1st rappel from the 2nd rappel station. be cautious when pulling your rope. there are many cracks and bushes your rope can get caught on!

Top of first rappel into the gully. make sure to tie knots into the ends of your rope!

Sinocranium far off

This is the view above the alcove where the rap anchor is. Go north from the anchor of P6.

Looking up from the base of Sinocranium. The first bolt is 20 feet off the ground so it is easy to miss the base of the route and go too far uphill.

Bottom of first pitch looking up entire route

Combined 4th and 5th pitches.
