Hydraulic head anomalously low. Symbol color on map indicates rock type at opening

Potentiometric contour—Shows altitude of potentiometric surface in alluvial-volcanic aquifer, in feet. Contour interval is 100 ft, except in area of Yucca Flat where interval is variable. Dashes indicate contour is uncertain: short dashes drawn where data absent or sparse; long dashes drawn where data available but contour based on conceptual interpretation. Datum is National Geodetic Vertical Datum of 1929

Hydraulic head and measurement location—Shows borehole name and head used to develop contours of the potentiometric surface in the alluvial-volcanic aquifer. Number is hydraulic head, in feet, at symbol location. A “>” or “≥” preceding a head indicates head used as a minimum; “<” or “≤” preceding a head indicates head used as a maximum. “±” following a head indicates head could be in error by more than 5 feet; “*” following a head indicates head for volcanic aquifer estimated from overlying volcanic confining unit (see appendix 2). Water levels used to calculate heads are tabulated in appendix 1
