Geography
Golog Prefecture is located in the southeastern part of Qinghai, in the upper basin of the Yellow River. Gyaring Lake and Ngoring Lake on the western edge of the prefecture are considered to be the source of the Yellow River. However, these lakes do receive water from rivers that flow from locations even further west, in Qumarleb County of the Yushu Tibetan Autonomous Prefecture.

The lay of the land of the prefecture is largely determined by the Amne Machin mountain range (max elevation 6,282 m), which runs in the general northwest- to-southeast direction across the entire prefecture, and beyond. The existence of the ridge results in one of the great bends of the Yellow River, which first flows for several hundreds of kilometers toward the east and southeast along through the entire Golog Prefecture, along the southern side of the Amne Machin Range, until it reaches the borders of Gansu and Sichuan; it and then turns almost 180 degrees and flows toward the northwest for 200 – through several prefectures of the northeastern Qinghai, forming a section of the northeastern border of the Golog prefecture.
