Excavation near Iurezan Bridge


In 1909 and 1910, Russian photographer Sergei Mikhailovich Prokudin-Gorskii (1863–1944) traveled extensively in the territory around the Ural Mountains, where he photographed railroad installations, factories, urban settings, and natural landscapes. In the summer of 1910 he traveled along the Samara-Zlatoust Railroad (built in 1885–90; now the Ufa-Chelyabinsk line), subsequently a link in the Trans-Siberian Railway. In this image, a curved track approaches a railroad bridge that crosses the Iurezan’ River (now spelled Iuriuzan) just to the west of Ust-Katav (in present-day Chelyabinsk Oblast). The track bed—one of a pair at this strategic site—has been cut through karst formations at the edge of the river. On the high left bank are telegraph poles. Such detailed technical photographs were part of the basic work Prokudin-Gorskii performed for his sponsor, the Ministry of Transportation. The hilly terrain in the background is covered primarily with conifer trees, including pine, spruce and fir. Prokudin-Gorskii used a special color photography process to create a visual record of the Russian Empire in the early 20th century. Some of his photographs date from about 1905, but the bulk of his work is from between 1909 and 1915, when, with the support of Tsar Nicholas II and the Ministry of Transportation, he undertook extended trips through many different parts of the empire.

Physical Description

Glass negative (presented as a digital color composite)


  • Prokudin-Gorskii’s photographic work survives primarily in two forms: 1,901 black-and-white triple-frame glass plate negatives, made with color separation filters, which Prokudin-Gorskii used to make color prints and lantern slides; and 12 albums of sepia-tone prints, made from the glass negatives, which Prokudin-Gorskii compiled as a record of his travels and studies. The Library of Congress purchased the glass plate negatives and the albums from the Prokudin-Gorskii family in 1948. In 2004, the Library of Congress had digital color composites made from all the surviving glass negatives using a software algorithm to automatically align the color components. As with most historical photographs, title and subject identifications are corrected and enhanced through new research.
