From August 1 to August 31, 2022, the staff of the laboratory "Landscape Archaeology" of the National Center of Archaeology of the Academy of Sciences of the Republic of Uzbekistan conducted an archaeological expedition in the Akhangaran district of the Tashkent region. The research works were organized to study the Paleolithic layers in the upper reaches of the Yangiabodsai and Karabakhsai, in the Muzbel gorge at an altitude of 3050 m above sea level. During the expedition, excavations were carried out at the Muzbel 1 workshop site belonging to the Middle Paleolithic. It is possible to emphasize the importance of this monument in the study of the Paleolithic of Uzbekistan. During the study, trenches measuring 2x1m and 6 meters were excavated, and it was also found that the third layer of four lithological layers is considered a cultural layer and is an extremely dense layer 0.30-0.35 m thick with light inclusions of limestone, crumbly granite and intermediate clays. The collection of the Muzbel parking workshop has about 200 artifacts, including small stone products that make up a single industry. Among the finds, the number of guns is a numerical disadvantage. The analysis of stone artifacts found at the Muzbel 1 workshop parking lot allows us to make preliminary assumptions about the monument's belonging to the group of Obirahmat cultural monuments. One of the problems that exist today not only for Uzbekistan, but also for the entire Central Asian Paleolithic, is the problem of preserving the cultural layer intact on open-type monuments. The location of the artifacts at the levels of the cultural layers of the Muzbel 1 monument, forming a relationship with each other, indicate that the cultural layers are well preserved.
