Life - More Nepal
Just had a quick play with Google Earth and came up with this picture. Lukla, the marked settlement in the foreground, is the airstrip we fly into from Katmandu. The group then treks up the valley on the left and round the spur into the valley on the right. Max height? About 3950m, where there's only about 60% of the O2 you'd expect at sea level. And yes, that peak in the centre distance is Everest.
