Which one is Everest?

Reaching the top of a hill, we finally come to a point where we should be able to see Mount Everest, but can't tell which mountain it is. Chris (left) stops to ask a trekking guide. You'd think that the world's tallest mountain (8,848 meters) would be easy to spot, but it's surrounded by so many other tall peaks, it's actually difficult to tell which is higher from where we're standing (about five days' hard walking from the Everest Base Camp).
