Map of the Region Mazar - Chiragsaldi La in the Kunlun Shan. The Highway 219 leads over the Chiragsaldi Pass to Mazar. The lila colored regions mark the places from where you can see K2 (8611m) in the Karakorum: From the Highway, not even from the Chiragsaldi Pass (see graph below), it will never come in sight. If you really want to see this mighty peak, you have to climb somewhat. The best view from a point that is accessible in a reasonable time is the peak in the South of pass (ca. 5370m). But this means a climb of around 420m! You have to be quite strong.
