4234-488: The latitude of its represented location due to convergence of the meridians. At lower latitudes, near 30° north, a 7.5-minute quadrangle contains an area of about 64 square miles (166 km ). At 49° north latitude, 49 square miles (127 km ) are contained within a quadrangle of that size. As a unique non-metric map scale, the 1:24,000 scale naturally requires a separate and specialized romer scale for plotting map positions. In recent years, budget constraints have forced

4380-477: The mission needs of the USGS. For instrument needs not currently met by a vendor, the Engineering Group designs, tests, and issues contracts to have HIF-designed equipment made. Sometimes HIF will patent a new design in the hope that instrument vendors will buy the rights and mass-produce the instrument at a lower cost to everyone. USGS researchers publish the results of their science in a variety of ways, including peer-reviewed scientific journals as well as in one of

4453-401: The mouth of the Stewart Glacier to McKinley Peak.

4526-465: The newest generation digital topo maps, including windmills, mines and mineshafts, water tanks, fence lines, survey marks, parks, recreational trails, buildings, boundaries, pipelines, telephone lines, power transmission lines, and even railroads. Additionally, the digital map's use of existing software may not properly integrate different feature classes or prioritize and organize text in areas of crowded features, obscuring important geographic details. As

4599-399: The north side of Edward VII Peninsula. Features in this area were explored by the ByrdAE, 1928-30 and 1933-35. These heights were mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photos, 1959-65. Named by US-ACAN (at the suggestion of Admiral Richard E. Byrd ) for Roy W. Howard of the ScrippsHoward newspapers, who made financial contributions to

4672-561: The northeast include the Wiener Peaks, Greer Peak, Morriss Peak and Mount Edwards. Features in the south include the Swanson Mountains, Mount Fonda, Mount Crabtree, Mount Treadwell, Wells Ridge, Mount Gilmour, Mount Ralph, Mount McCormick, Mount Little, Mount Swan and Post Ridge. The mountains were explored by the Byrd Antarctic Expeditions (ByrdAE; 1928–30 and 1933–35) and by the United States Antarctic Service (USAS; 1939–41) all led by Rear Admiral Richard E. Byrd . They were named for Admiral Louis E. Denfeld , Chief of Naval Operations and

4745-434: The northernmost of the Wiener Peaks. Mapped by the USAS (1939-41) led by R. Admiral R.E. Byrd. Named for Doctor William E.R.

The peak was mapped by the USAS, 1939-41, led by Byrd, and by

4818-469: The onshore and offshore geologic framework; assess mineral resources and develop techniques for their discovery; assess water resources and develop an understanding of the impact of human activities and natural phenomena on hydrologic systems; assess links between biodiversity, habitat condition, ecosystem processes and health; and develop new technologies for collection and interpretation of earth science data. The USGS National Geomagnetism Program monitors

4891-428: The primary topographic quadrangle for the state of Alaska (and only for that particular state). Nearly 3,000 maps cover 97% of the state. The United States remains virtually the only developed country in the world without a standardized civilian topographic map series in the standard 1:25,000 or 1:50,000 metric scales, making coordination difficult in border regions (the U.S. military does issue 1:50,000 scale topo maps of
