Toward the east, the ridge descends to a much lower level at Bud Datu, Bud Agad, and Bud Pula, which lie immediately to the south of Jolo. It rises again in Mount Dahu to an altitude of 716 meters. Mount Dahu is a prominent landmark and forms the most picturesque landscape in the background of Jolo. It is a steep and conical extinct volcano, similar to, but smaller and more regular in form than Mount Tumangtangis. East of Mount Dahu is another gap in which lies Tambang Pass. Beyond this the range rises again at Mount Tambang and continues uninterrupted to Mount Sinuma'an, at the extreme end of Lati, and Mount Bagshag. After Mount Bagshag the range descends gradually toward Su' and Si'it. The northern slopes of Mount Tumangtangis and Mount Dahu, and the crest of Bud Datu are covered with grand forests, while the crests and lower slopes of Bud Agad and Bud Pula are partly cultivated and partly covered with tall grass. From the shores of the Bay of Jolo the land rises gradually and presents a beautiful green appearance. The northern aspect of this whole range and its beauty were appropriately described by Mr. Hunt, as follows: There are few landscapes in the world that exhibit a more delightful appearance than the seacoasts of Sulu; the luxuriant variety of the enchanting hills exhibits a scenery hardly ever equaled and certainly never surpassed by the pencil of the artist. Some with majestic woods that wave their lofty heads to the very summits; others with rich pasturage delightfully verdant, with here and there patches burnt for cultivation, which form an agreeable contrast with enameled meads; others, again, exhibit cultivation to the mountain top, checkered with groves affording a grateful variety to the eye--in a word, it only requires the decorations of art and civilized life to form a terrestrial paradise. [7] To the south of Bagshag [8] lies a small extinct volcano called Panamaw or Pandakan, whose crater is now a lake. East of Si'it rise the Lu'uk mountains of Urut, Upao, and Tayungan. From these the range extends to Bud Tandu at the eastern extremity of the island. The highlands near the southern coast of the island divide into three separate regions. The first and westernmost lies west of Maymbung and forms the principal highlands of Parang. The highest points in this region are Mount Tukay, east of the town of Parang, and Mount Mabingkang, east of Tukay. To the east of Maymbung rise Mount Talipao and Mount Kumaputkut, which form the middle and second region. The third region is the southern part of the Lu'uk country. Its highest point is Mount Bulag, to the north of Tandu-Panu'an. Between Mount Tukay and Mount Tumangtangis lies Bud Gapang. Midway between Mount Talipao and Bud Datu is Mount Kumuray, in the neighborhood of Langhub.
