Unknown mountains along the Karakoram Highway

Here's an image I took on an expedition to climb Muztagh Ata in July of 2013. I have uploaded a large resolution version of this photo in hopes that others will appreciate the size and scale of the mountains in this region of the world. I have no idea what peak this is, but the face is a menacing slab. I can't even imagine what lurks 1 valley north of here. Feel free to download this image, but it is not to be used without the author's explicit consent.
