and parallel toUV, permit location of the contact (cc) with fair degree of proba-bility at an average depth of 170 feet. In the section representedby YZ, 3 miles east of and parallel to WX, the influence of the lacus-trine deposits does not appear. The sulphate water in one well nearHanford probably comes from a small spot of alkali. The shallowwells in the southern part of this section are affected by the sedimentsof different character in Kern County. TOTAL MINERAL CONTENT OF WATERS. Additional evidence that the highly mineralized condition of theaquifers under the lake is caused by saline residues is afforded by theresults of other tests besides those for sulphate. All excessiveamounts of chloride and bicarbonate in ground waters near the lakewere found either west of or almost exactly in the position indicatedby bb (PL III), a fact indicating that bb represents the eastern limitof the zone of highly mineralized waters and also indicating concen- CONDITIONS ABOUND CULABE LAKE. 107
