This map can be found in an appendix to the second volume of Труды тибетской экспедиции 1889-1890 гг. подъ начальствомъ М. В. Певцова [Works of the Tibetan expeditions 1889–1890 under the authority of M. V. Pevtsov] edited by M. V. Pevtsov and published by the Russian Geographical Society in 1892.

Based on data gathered by geologist and mining engineer K.I. Bogdanovich, this route survey shows an area around the Yarkand River located southwest of the city of Yarkand. The Yarkand River is one of the headstreams of the Tarim River. Connected rivers and the surrounding terrain are sketched out in this map, and names of passes and mountains are noted. Tahta Hon is marked out to the east of the map.

Seven other maps can be found in appendix to the same volume: one large-scale overview of Eastern Turkestan and four additional small-scaled route surveys of areas to the south and west of the Takla Makan Desert, as well as two sketch-maps of areas with gold mines.
