Stein (1981: 14-15, on his map "L'habitat et les habitants") identifies this land with present-day Ladakh or its central area around Leh, Denwood (2008: 9) locates it in the Rudok area, alternatively also in Nubra, whereas according to Thomas (1935: 153) it would be identical with HunzaNagar.
To be exact, a journey straight south of Khotan would lead us to Rudok rather than to Leh.
Thus, if we were permitted to transfer the indication of 1000 li for the west-east extension of Greater Yangtong to Suvarnagotra, the distance would well cover both Leh and Rudok, whether we locate the country along the Indus River (in which case, the distance of 325 km or more would almost cover the entire distance from the source to Leh) or whether we locate it more to the north in the Changthang.
Initially, I would have taken possibility (c) for the most likely one, with Maryul simply referring to the gold fields near Rudok and the adjacent areas.
365) refers to the Rudok area, but perhaps also to more eastward areas (see also below).

(6) With Garhwal business relations must have been constant, at such times as guerilla warfare with the frontier rajahs or the blocking of the passes by snow did not temporarily obstruct them; Tsaparang must have been the centre where stores were replenished by all the neighbouring provinces from Spiti to Rudok and Thok Jalung.
The provinces are Rudok (=Mang Yul?), Guge and Purang.
