Kham
Kham
the southeastern outskirts of the Tibetan upland, south of the upper course of the Hwang Ho in China. High mountain ridges (the Bayan Hara Ula, Russian Geographic Society, and Woodville Rockhill ranges) divided by the deep gorges of the upper reaches of the Yangtze, Mekong, Salween, and Yalung rivers and stretching mainly from the northwest to the southeast are predominant. In the northwest there are high-mountain steppes and sedge-Kobresia meadows. In the south and along the slopes of the gorges are fir and spruce forests, shrub thickets (juniper, honeysuckle, hawthorn, and barberry), and rich mixed grasses. There are perpetual snows and glaciers on the summits of the ridges. In 1900, Kham was studied by the Russian explorer P. K. Kozlov.
