i <br /> THE NUMBERING SYSTEM <br /> r <br /> 11S/17E-22A1 <br /> ISI <br /> 40 4D, <br /> 6' <br /> rCp <br /> r r <br /> r <br /> I i <br /> r <br /> s <br /> r � <br /> ' The numbering system now in common use in California has been used by <br /> the Geological Survey since 1940 Wells and surangs are assigned numbers <br /> ' according to their location in the rectangular system for the subdivision of <br /> public land For example, in the number 115/17E-22,41 M, assigned to a well <br /> about a mile west of Madera, the part of the number preceding the slash <br /> indicates rhe to-i-ship (T. ll S ) and the numoer between the slash and hyphen <br /> indicates the range (R 17 E.) , the digits following the hyphen indicate the <br /> section (sec 22) , the letter following the section number indicates the <br /> 40-acre subdavIsion of the section as shown by figure 1. Vithin each 40-acre <br /> tract, the wells are numbered serially, as inaicated by the final digit. Tne <br /> final letter, separated from the rest of the number by a space, indicates the <br /> base line and meridian Base--line and meridian designations are as follows <br /> H, Humboldt, M, Mount Diablo, S, San Bernardino <br /> The system for numbering springs is identical to that for wells exce_ot <br /> that the letter "S" is added after the letter which indicates the 40-acre <br /> subdivision Thus, if the number described above were for a spring, at would <br /> be written 11S/17E-22AS1 N1 <br />
