Rupshu - region in south-east Ladakh, in the northernmost India state of Jammu & Kashmir, at the western end of the Changtang plateau. High (few places are below 4500m) and wild, studded with beautiful lakes (tso), it offers almost unlimited possibilities of mountain exploration, with many peaks rising above 6000m. The trek, in summer 2011, was organized by Luke Smithwick (then) of Project Himalaya. We started by following the "standard" trekking route from Rumtse towards Tso Moriri for a couple of days. After passing Tso Kar we turned east to explore some 6000ers above Spanglung, including "Rupshu Ice Cap". A few days of further trekking brought us to the foot of Korzok range, where we did some more exploring and climbing, including glaciated Peak 6260m. Return to civilization involved, among other things, crossing a 5900m pass, which our horses and we did cross, with no major problems.
