The article considers the role of Boris Filippovich Lut (1930-2021) in the study of the relief of the bottom and shores of Lake Baikal and the formation of the Baikal depression. The chronological framework of the article is defined by the second half of the 20^th century and covers the period of scientific and scientific-organizational activity of B.F. Lut, a famous Soviet and Russian scientist-geomorphologist, Baikal scholar, candidate of geographical sciences, and author of more than 200 scientific papers. His major geomorphological works include dozens of maps, diagrams, profiles, graphs, and photographs, which provide excellent illustrations of natural processes on the shores of Lake Baikal. The article provides an overview of his expeditionary fieldwork on deep surveys of Lake Baikal, geomorphological study of the bottom and shores of the lake, processes of relief formation, formation and geodynamics of the Baikal depression, and practical application of geomorphological knowledge. During the construction of the Baikal-Amur Mainline (BAM) on Northern Baikal, based on the work of B.F. Lut and his colleagues, the tunnel railway option was chosen as more economically and environmentally efficient than the “coastal” route, which would degrade the natural environment. B.F. Lut’s research into the Baikal depression, and particularly its underwater part, is a significant contribution to the geomorphology of the Baikal mountain region and is still in demand today, as evidenced by references in Baikal studies publications.
