During the expedition, Adrian Hajszán, Zsuzsa Dömötör, Márton Bence Balog, Péter Balázs Terényi, Szabolcs Kocsmár, and Associate Professor József Sátmári compared Gyula Prinz’s descriptions and sketches, György Almási’s photographs, with their own observations and images of the current state of the landscapes, glaciers, and the hydrographic conditions of the region, and conducted drone surveys.

For example, during D. Prinz’s visit in December 1906, there was no water in Lake Köl-Suu. On the shore of Lake Köl-Suu, modern researchers observed the advantages and disadvantages of the tourism development predicted by D. Prinz.

In September 1909, he discovered the lake and named it Lilly after his wife. Today, this lake is known as Köl-Tör. In a comparison, researchers from the University of Szeged found that the snow patches had disappeared and the water level had dropped by at least two meters.

To assess the rate of retreat of the Tien Shan glaciers, the researchers compared D. Prinz’s maps from 1906 and Soviet military maps from the 1970s with drone-based survey data, satellite images, and field measurements. According to the scientists’ observations, mining activities, infrastructure development, and glacier retreat have led to significant environmental changes.

Their report notes the replacement of irrigation canals near Osh with modern water supply systems, due to a change in the main objective from irrigating agricultural land to providing the population with water.
