Thanks Janne for this excellent page on an additional unknown Tibetan peak.
As you mention in your page, the described route (East Couloir) is free of snow in the warmer month, especially in its lower section (see this picture from October 2007).
The long NE ridge might offer an interesting alternative and can be accessed from the same valley at the pass 5732m (28°51'59.90"N/90° 8'53.60"E) between P5830m (28°51'58.60"N/90° 9'9.30"E) and P5861m (28°52'8.50"N/90° 8'39.40"E).
From where is that photo taken more exactly? The easiest way to the summit must be the one Eran and Fredrik tried. The long walk on the ridge. You were up there as well if I remember correct? This photo indicates that. Eran and Fredrik turned back though, as they thought they were on the actual summit.
A little remark. The GPS reading on the summit was 6028m and it was a good one. I think the map is off.
a)Shot location of North face picture: Lat 28°54'15"N Lon 90°07'25"E, alt. approx. 4800m, on the road approx. 5-6km below Karo La
b)Shot location of Northeast ridge picture: small summit 5830m Lat 28°51'58.6"N Lon 90°09'09.3"E.
The NE ridge and the west face (or ridge) are really two dinstict routes, you can see the NE ridge (green) and W face (red) in this GE image and that GE image. I am not sure what route they take in their attempt, but I guess they ascended from the west (route in red).
About the altitudes, I also got systematically higher GPS readings in the area (e.g. Kaluxung 6686m instead of 6674m), but in the new area/range page I am working on right now, I preferred to use the altitude given by the map for better clarity for the reader. In the pictures, I'll try not to forget to put both altitudes.
