- This map was created for use by a Soviet government research institute. By means of the color coding, it shows regions in Siberia where hydrogeological investigations had been carried out and divides those regions into three categories: detailed and special hydrogeological investigations from prospectors' experience…on a scale of two versts per inch; general hydrogeological investigations…more than two versts per inch; and geological, hydrogeological, soil, and other investigations eliciting the presence of underground water. The white areas, occupying by far the largest part of the map, indicate where neither detailed nor general investigations had yet been carried out.
