In Tawngpeng to the northward, a mass of hills, the loftiest range rises to 7500 feet. East of the Salween, the hilly tract of Kokang has heights of over 7000 feet; south of this is a tangled maze of hills. In the Southern Shan States, five separate ranges run approximately north and south with many conspicuous peaks, Sindaung and Myinmati (each 5000 feet) on the western border; Ashe-myin-anaukmyin in the Menetaung range; Loi Maw and Loi Mai (each 8000 feet).
East of the Pegu Yoma, in Toungoo the Paunglaung and Nattaung ranges rise above 5000 feet. The Paunglaung continues southward into Thatôn. On the Siamese border are the hills forming the Salween district, with heights from 3000 to 5000 feet. Thatôn and Amherst have the Dawna range and the Taung-nyo range which ends as the Martaban Hills; and in Thatôn the Kelatha Hills take off from the Paunglaung and attain heights of 3650 feet. Further south, the inland parts of Tavoy and Mergui consist of hill ranges extending eastward to the frontier of Siam, in which the highest peaks are Myinmoletkut (6800 feet) and Nwalabo (nearly 6000 feet).
West of the Irrawaddy, the Kinwun range runs from Hkamti-lōng, east of Assam, culminating in the peak of Shwe-daung-gyi (5750 feet) near Mogaung. South of Mogaung are the Kauk-kwe Hills and the Loi-yet range. Further south, Katha has many hills, the best defined ranges being the Minwun which takes off from Taungthônlôn far to the north, with the height of Maing-thôn (5450 feet) and the Gangaw, parallel to the Irrawaddy, rising to 4400 feet.
In the extreme north, on the edge of Tibet, are superb chains of mountains culminating in a mighty peak, as yet unnamed, 19,764 feet in height, at the limit of the Putao
