My three weeks in Nepal were mainly spent trekking the famous Annapurna Circuit. This trek started at around 1000 meters elevation above sea level, and peaked to 5416 meters at it's highest point. These elevation changes made for huge shifts in the landscape, specifically in the vegetation, color and climate. We started out in humid, lush rainforest, following close to a raging river. This made for scenes of many shades of green. We then emerged into great mountain valleys filled with pink buckwheat fields and dwarfed on either side by numerous peaks. As we climbed up into more mountainous terrain, the greens became darker as pine trees dominated the landscape. Eventually, we found ourselves above the tree line, with nothing but barren rocks and sleet surrounding us for miles. Up in the mountains we climbed along the ridge line to the famous Tilicho Lake. The highest lake in the world (4949m) boasted crystal clear blue water surrounded by huge ice blocks plunging into its depths. It was also guarded by massive glaciers, whose peaks pierced the sky at 7000m, and would only tease you with their magnitude and presence with the rare break in the clouds. Finally, with the air growing thinner, we reached the highest pass in the world, Thorang-La Pass, at 5416m. From there, we started to make our way back down to 1000m, reversing the changes in landscape, coming full circle and finishing where we had started, in the rainforest.
