After Auden's Col the character of the trek changes. For three days you are in glacier country, then back into forest and meadow. The route runs through the Khatling Glacier system, in a landscape mapped with Jogin Bamak, Ratnagiri Glacier and Rudragaira Bamak.
Khatling Glacier Camp
Day 9 ends at the Khatling Glacier Camp, at 4,860 m, a minimal alpine camp. Day 10, the reserve day, is spent here if it is needed. The itinerary shows 1 hour and 1 km for the day, because it is a rest and reset day, not a walking day.
Down to the snout
Day 11 goes from the glacier camp to the Bhilangna Snout Camp at 4,025 m, 5 to 6 hours and 8 km. The Bhilangana river rises from this glacier, and you walk down toward its snout. The ground is moraine and loose rock, and footing needs attention. Water sections are crossed only on the leader's instruction. The descent of about 835 m is a relief after the col, but a tiring one.
Tambakund and Chowki
Day 12 is a transition day to Chowki at 3,620 m via Tambakund, 5 to 6 hours and 10 km. It is where you regain rhythm after the glacier. There are wet crossings, so dry your socks and feet at the end of the day.
Then up again
Day 13 climbs from Chowki to Masar Tal at 4,568 m, 4 to 5 hours and 8 km. The altitude returns quickly, so pace matters again. Reach camp early and keep the afternoon quiet.
The river names along this stretch, the Bhilangana among them, are worth knowing if you like to read the map as you walk. The mapped rivers on the whole route are the Bhagirathi, Kedar Ganga, Bhilangana and Vasuki Ganga, with the Mandakini at the end.
If you want to see this glacier and the col without the full three-pass traverse, the Mayali Pass trek covers the Khatling side.
