New Wall at Donner Summit

I found a wall with probably around 10 bolted sport routes (~40ft?) about halfway between Goldilocks and Snowshed. It's not on MP or the Horniak book, does anyone have any more info about these routes?

If this is still being developed and people don't want this public just yet please let me know and I will delete this post.

I have also wondered about this, I have seen some guided parties on the east slabs above. 

Are you talking about the wall with the old road/highway at the base and the tunnels above it? Don't know who developed the crag and it's more like 5 bolted routes than 10. Most are pretty fun, the shortest ones (far left and far right) are the best and in the .10+ range. 

I don't think you posting about here is blowing up someone's secret spot, it's public land and the crag is easily visible from the road.

Yeah right below the actual train sheds but above the maintenance road. Funny enough there's actually a tier above the furthest right with more climbs on top, quite a few routes. I only did the far right bolt line and it was pretty fun.

I have a guide friend who says they frequently guide there. I believe it was developed with that in mind? I can’t remember for sure and I’m seemingly always taken with the more known climbs so I haven’t climbed there yet, though I did a fair amount of Donner obscurity exploration when I lived closer.

Sounds like Petroglyph Cliff. Or thats what I have always heard it called. 

At least 3 of the local guide services use it. 

The name refers to the petroglyphs close to Donner pass road that this cliff overlooks.
