Geosphere, February 2008, v. 4, p. 218-246, doi:10.1130/GES00126.1, Figure 11 - A full resolution version of Figure 11. Subsets of Plate 3 showing modern hot springs at which siliceous or travertine sinter deposits were identified using the ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) data. (A) Quartz identified at hot springs along east flank of Ruby Mountains in Ruby Valley, Elko County (H, Fig. 6). (B) Carbonate identified in travertine deposits at Potts Ranch and Diana's Punchbowl hot springs in Monitor Valley, Nye County (I, Fig. 6). (C) Quartz identified at the Geysers and Beowawe hot springs, Eureka County (G, Fig. 6). Geology polygons are not shown in B and C for simplicity. Significant quartz was identified between the Geysers and Beowawe that represents outflow deposits from the Geysers spring. Sinters and/or tufa deposits (QThs) from the geology coverage of Crafford (2007) are outlined in cyan in Plate 3. Quartz or carbonate was not identified at several of these deposits. ASTER emissivity spectra of the Beowawe, Diana's Punchbowl, and Potts Ranch hot springs are shown in Figure 5. File size is 0.2 MB.
