Description:Excerpt from Contributions to Economic Geology, 1907, Vol. 2: Coal and Lignite During the year 1907 a greater addition was made to existing knowl edge regarding the outline, extent, quality, and tonnage of the western coal fields than had been made in any previous year. This was due largely to the fact that during the latter part of 1906 and the early part of 1907 supposed coal lands to the extent of acres, or square miles, were withdrawn from entry, and the United States Geological Survey. Was called upon to examine and to classify these lands so that they might be restored to coal entry. Before this work was done it was impossible to determine with any degree of accuracy the positions of many of the coal fields in the Rocky Mountain region, or. To say what were their sizes and shapes and the extent of their coal resources. Now, however, the coal areas are much better known, and a map representing them has been pre pared. A copy of this map on a small scale, in black and white, is here given (pl. I) for the purpose of showing the extent of the coal fields and the areas in which surveys were carried on during the last year.
