Fig. 3. Gravimetric water abundance profiles and clay abundances in drill holes LAOI(A)-1.1 and R-8 within Los Alamos Canyon. Note that the lower horizontal scales, for weight % water and clay, differ for the two drill holes (R-8 is wetter), and clay data for R-8 cover a more limited depth range than the moisture data. The figure for LAOI(A)-1.1 also shows hydraulic transmissivity data (Ksat, cm/s; Stephens et al., 1995). Hachures in the figure for LAOI(A)-1.1 indicate near-vertical clay-filled fracture zones; other markings indicate a pumice swarm and a horizontal fracture zone as marked.
