Description


This is a highly detailed large format map of Colorado issued by the General Land Office in 1921. The map covers the entire state with color coding designating National Forests (Green), American Indian Reservations (Yellow), National Parks (Purple), Military Reserves (Red), and Reclamations Projects (Blue). The major reclamation projects, which take the form of enormous irrigation dams, appear here in western Colorado and include the Grand Valley Project and the Uncompaghre Projects. Lesser reservoirs appear here and there throughout.
Publication History and Census
This map was compiled by A. F. Dinsmore, traced and lettered by William Bauman, Jr. and published by the Department of the Interior General Land officer under the supervision of Ithamar Parsons Berthrong. It was published in various editions from about 1910. The map is well represented institutionally, but uncommon on the private market.

The General Land Office (1812 - 1946) was an independent agency charged with the administration and sale of public lands of the western territories of the United States under the Preemption Act of 1841 and the Homestead Act of 1862. During a time of frenetic energy and rapid westward expansion, the Land Office oversaw the surveying, platting, mapping and eventually the sale of much of the Western United States and Florida. The structural layout of the western United States that we see today, and many of their district and county divisions, are direct result of the early surveying work of the General Land Office. More importantly, as a branch of the Federal Government in Washington D.C. and the only agency able to legally sell and administer public lands in the western territories of the United States, the General Land Office played a pivotal role in consolidating power away from the original states and into the hands of the centralized federal government. The General Land Office was absorbed into the Department of Interior in 1849 and in 1946 merged with the United States Grazing Service to become the Bureau of Land Management. Today the Bureau of Land Management administers the roughly 246 million acres of public land remaining under federal ownership.


Ithamar Parsons Berthrong (February 26, 1853 - July 29, 1936) was an American surveyor, inventor, and draftsman active with the General Land Office of the U.S. Department of the Interior. Berthrong was born in Rochester, New York. He was made chief of the drafting division on March 23 of 1907. He is associated with many of the most important early 20th century maps issued by the GLO, among them, important maps of Arizona, Colorado, Wyoming, Oregon, Washington, and more.
