South of Chamdo the Dzachu, the Drichu and the Salween run close together in steep gorges: Markam (Mangkang), Zogang and Baxoi lie in side valleys of the Dzachu and the Salween's tributaries.
Wikipedia's Tea Horse Road page says the Sichuan-Tibet branch (Ya'an, Dartsedo, Lhasa) and the Yunnan-Tibet branch (Pu'er, Dali, Lijiang, Shangri-La, Lhasa) met near Markham County on the upper Mekong, and dates the formation of the Yunnan branch to the late 6th century. So Markam is a road junction on the old map. What the traffic was in 1200 is not in our sources: the Song's Yazhou trade went west by Dartsedo, and Dali's own trade with Tibet is not documented for the year.
The valleys themselves are held by small hereditary chiefs with fortified houses and villages.

- 1253Uriyangkhadai's column marches from Lintao through Kham towards Dali and the Jinsha (Wikipedia, Dali Kingdom).Depends on: Kublai's south-western campaign. Stopped by: A Mongol failure at Lintao or Dali, or a campaign turned elsewhere.
Places of note
- Markam (Mangkang): Valley centre and junction of the roads.
- Zogang (Wangda): Valley centre.
- Baxoi (Pasho), approximate: Valley centre.
Where the sources disagree
- Wikipedia's Kham article, the only page we could read on the point, lists the polities of Kham without dates or chiefs and says Kham had no single ruler, 'a mix of kingdoms, tribes, and chiefdoms whose authority shifted often'. Everything below that is not tied to a named source is the general pattern of a Khampa valley, marked as such.
- Wikipedia's Tea Horse Road page dates the Yunnan-Tibet branch to the late sixth century and describes the meeting at Markam as a fact of the road, not of a year; we use it for the road only.
Evidence: One Wikipedia paragraph on the roads; no political source.
On the map: Ground is drawn in the province record Markam.
