Show Topographic mapping project now Underway in Crew's headquarters in Roosevelt Engineering field parties of the Topographic U Geological Survey are now engaged in surveying operations for the preparation of accurate topographic maps of miles of Duchesne and Uintah Uintah With Roosevelt as their six field under the direction of B. project arc working an area extending from Vernal south to and west through Duchesne and Party chiefs are R. F. E. E. T. L. J. B. D. L. and J. F. Bruce Holman Bud Keith Kirk Heaton and Scott Todd are serving as topographic field In Vernal another smaller group under the supervision of A. Stephens is in this Party chiefs are J. and H. R. L. Gunter and Ashel Evans are serving as topographic field The finished topographic maps are published in rectangular called They show political and all other man-made as well as the courses of and other water In the maps depict the shape and slope of the land its hills and and give its altitude above sea maps of adjacent areas can be joined to show any desired such as a a or a school Topographic maps serve as a basis for the study and solution of many problems relating to activities that are affected by the character and relief of the earth's The problems may involve mineral or water prospecting and engineering construction of all location of industrial urban military requirements and Good maps facilitate the development of all projects that deal with the Although any one mapping project may be partially related to a particular development program or a specific the topographic mapping of the Geological Survey is done essentially because these maps have a general-purpose and because it is sound economy to have them on hand for any specific planning that future developments or Investigations might In the preparation of these maps the most modern engineering methods are Aerial photograph and precise instruments are part of the basic mapping but field surveys are still required at two The first of these is to establish control that elevations above sea level and geographic The second is to check the accuracy of the map as drawn from the aerial and to complete the Identification and classification of political other The are now in progress in this The cooperation of local residents and landowners in assisting the field parties engaged on these surveys will be greatly Over topographic maps have been published by the Geological Survey and several million copies are distributed Available without charge arc state indexes showing areas covered by published a folder describing topographic and a brochure entitled Geological Most of the topographic quadrangle maps arc sold for 30 cents a copy and may be ordered Geological Federal Denver Copies of the aerial photo and geodetic control lists used for this mapping are available at nominal charge from the of- fice listed For further information write Pacific Region Engineer U.
