On page 7 (table 1), the headnote has been modified to include "Well depth, study depth (original depth)." Under the "Well depth" column, the original depths, in parentheses, have been included next to the study depths.
On page 29 in the last paragraph that starts in the left column, the second sentence has been revised to "The slopes of fit-lines for δD and δ18O ratios for precipitation in Clovis (Nativ, 1988) and ground water at the Range (fig. 14) are similar and both less than 8 (enrichment of heavier isotopes), which is indicative of local effects."
On page 31 (fig. 14), the third line of the explanation has been revised from "Clovis ground-water line (Nativ, 1988)" to "Clovis meteoric water line (Nativ, 1988)." The misspelling of "oxygen" on the graph's abscissa has been corrected.
