Map showing springs in the Salina quadrangle, Utah

A spring is “a place where, without the agency of man, water flows from a rock or soil upon the land or into a body of surface water” (Meinzer, 1923, p. 48).About 450 springs are located on this map. Locations and names are from the U.S. Forest Service maps (1963, 1964) and from topographic maps of the U.S. Geological Survey, both published and in preparation. There is considerable variation in ge

Maps showing distribution of anomalous amounts of selected elements in stream-sediment and rock samples, Eagle quadrangle, Alaska

Maps showing the distribution of anomalous amounts of selected elements found in more than 1,600 stream-sediment and more than 1,500 rock samples have been prepared form results of semiquantitative spectrographic analyses. The samples were collected in the Eagle quadrangle, east-central Alaska, in the summers of 1968, 1969, 1970, and 1971. Figure 1 is a map showing localities for all stream-sedime
