Today, I woke up at 5:00am, packed up my equipment, ate a quick breakfast in the mess tent, and began the trek to Urdukas. The morning was cloudy and cool and the sunrise over the Trango Towers was beautiful. About an hour into the trek, we gained the Baltoro glacier and proceeded up and down over glacial moraine until we had crossed the width of the Baltoro Glacier. The cloudy morning gave way to a clear afternoon which yielded stunning views of the jagged rocky peaks of the Karakorum covered in fresh snow. We broke for lunch at Koburtse (3850m/12,630ft) and waited endlessly for the porters to arrive then continued on to Urdukas. The route had changed considerably from the one I took last year and proceeded over avalanche and land slide debris. Once we arrived to Urdukas, we quickly claimed a camping spot. It began snowing again in the afternoon and a trekking group was gracious enough to invite Marek (Czech Republic) and me into their mess tent for tea. We chatted for a bit and after an hour or so, our equipment arrived and we headed down to our own mess tents for dinner. The night was cool and after dinner, I quickly got into my sleeping bag and went to sleep early. Tomorrow, we will trek to Goro II.
