Kali SALZE UND ANDERE SALINES IM GREAT BASIN REGION. 63 Einen See in die andere, und vielleicht die Annahme, dass es keine starke Zustrom von einem See und in der anderen die auf die Tatsache am nächsten ist. Dies würde führen uns zu dem Schluss, dass in jedem dieser Becken wir erwarten konnten Salines in der Tiefe. Die gegenwärtige Tiefe der Pyramide und Walker Seen, unnötig zu sagen, würde die Explorationsarbeiten in diesen Gemeinden entgegen. Die Profile der Pyramide, Winnemucca, Mono, und Walker Seen sind in Abbildung 7 dargestellt. Diese Profile zeigen die de

POTASH SALTS AND OTHER SALINES IN THE GREAT BASIN REGION. 63 one lake to the other, and perhaps the assumption that there was no considerable flow from one lake into the other is the nearest to the fact. This would lead us to conclude that in each of these basins we might expect salines at depth. The present depth of Pyramid and Walker Lakes, needless to say, would preclude exploration work in these localities. The profiles of Pyramid, Winnemucca, Mono, and Walker Lakes are shown in figure 7. These profiles show the deepest portions of the lakes to be in the central part or away from shores or inlet streams. Topographic evidence goes to show that the saline deposits in Black Rock Desert must'have been spread over a great area and must have been relatively thin. The difficulty of pros- pecting or exploring has been commented upon. Carson Lake is comparatively shallow and would not offer serious obstacles to exploratory work. The fact that the Carson Sink receives the drainage of both the Humboldt and the Carson Rivers, each of which drains relatively large areas, as well as the extent of the Quaternary lake, makes this basin comparatively attractive for exploration. The greater area of the Carson Desert and the difficulty of securing accurate information from surface studies as to the probable structure of this basin would render a search for salines almost as difficult as in the Black Rock Desert. The U. S. Geological Survey put down a bore in the Carson Desert at what was hypothetically assumed to be the axis of the deepest depression in the Quaternary lake basin. The site of the bore is close to the north end of Timber Lake in sec. 30, T. 21 N., R. 30 E. The bore was sunk to a depth of about 985 feet and failed to penetrate either saline beds or brines. The log of the bore to a depth of 320 feet is lltli|i|f|i|iMfiiiifi'i|ffli|ff^^. Fig. 8.—Cross sections showing probable conditions exis
