Pan around with your mouse (or finger) and zoom in and out. Even better - go full screen!
There are 6 panoramas here along the Baltoro Glacier to Concordia and back.
It is an interactive panorama so you can pan around and zoom in and out. The right most button in the tool bar gives full screen. The "M" button in the newer tours toggles a Google Map with clickable markers. The radar icon on the top right shows orientation and field of view. Most are multi resolution so when you zoom in there may be a slight delay as the files load.
