"The description of this route refers to the Summer months only. With the exception of the RUDO LA and DONGA LA it is every where good enough for laden mules. These passes are barely possible and are very difficult owing to the steep ascent over stones and slippery roots through the jungles on the West side, and owing to the extremely steep descent down rock steps on the East side of the RUDO LA...Note. The map names are in many cases wrong, and very often wrongly spelt. As far as possible, the correct spelling is here given, and map names are given in brackets. Heights are only approximate."

"This route is an alternative to the one which crosses the DONGA LA to LHUENTSE. It is hardly ever used, and there was no path visible in July 1933. Under the best conditions it would be impossible for laden animals....For the first two stages see route TRASHIYANGSI to the ME LA. From TOBRANG onwards see below."

"For the first two stages see White's route in 1906. TSEKANG, his second stage, is no longer inhabited, and there is no inhabitants beyond SAWANG until SINGHI DZONG, where there is a small monastery. SAWANG should therefore be made the second stage. This route is frequently used by traders between LHUENTSE and LHAKHANG DZONG. It is open throughout the summer when the direct route up the KURU CHU is closed on account of too much water in the river. The KANG (GONG) La is normally closed by snow in October or early November. The route is possible throughout for laden ponies, but the KANG LA is very difficult on the north side, where the route lies over a glacier for about a mile."

"The route throughout is easy for laden animals the road being broad and excepting two or three places fairly level. Between LHAKHANG and TOWA transport is changed very often."
