From the lake, we traverse under Sherkhota volcano, then start climbing through boulder fields toward the pass. Before the saddle, there's a steep scree slope and the red flanks of volcanic cones (Big and Small Khorisar). You can see Truso Valley from the pass. The descent is long, rocky, and drops elevation quickly. We'll reach the upper Keli Plateau and set up camp in a shallow hollow. Reliable water sources are scarce here, so we'll fill up in advance.
