Wilderness of Rocks Domes 

Wilderness of Rocks Dome, AKA, Twin Peaks, Mystery, North Dome is located below the antenna at the top of the road past Ski Valley.
You can see the back of it from just below the road.

Approach it from Marshal Gulch. It is about 20 min past Primus Wall (aka trailside craig)

When the trail starts to head down to the south, and you are about even with the low angle slab on the hill to your right, look for a large pine tree and a route to the right and down, across the drain, then up to the dome.

The FA's on the original lines remain a mystery. My guess is that they were put up in the late 70's. The area got a couple of new routes in 2010.

The routes lack sustain which may eliminate the stars in some opinions, however the atmosphere warrants stars. there is good water for the dogs.

Mystery Route Center, has a leeper on the first pitch, but it can be backed-up with a cam.

Mystery Route Left has a bolt for the last move that can be backed up with a 3 cam, kind of.

Mystery right; takes a small nut off the deck and some larger cams the rest of the way. bring a tool to clean the dirt out of the nut placement.

Tony's routes have bolted anchors however they are not rap anchors.

Each of the two peaks have bolted rap anchors, 1 rope rap off the backside.

It is easiest to scramble down the west side, stay on the rock all the way to the bottom before crossing the water.

watch for bees and ants.

FAs were probably done by Karl Rickson and company.
I know he spent a fair amount time in the area.
Chances are good that anything you do without a drill that is 5.10 or under has seen a prior ascent.
The nice thing though, who cares, for you it's the same as an FA and for that, Karl would be very happy.
