Fig. 1. Layered fluvial outcrop at Rio Bravo. (a) View of outcrop taken during the final stages of infiltrometer installation and showing the contact locations of the five mapped units (see Table 1 for geologic description). The orange flags provided a 40 by 40 cm reference grid. (b) Oblique view of outcrop showing the outcrop profile. The infiltrometer is installed right of center just beyond the edge of the photograph. Note, these photographs should be seen in color and are best viewed on a computer screen where one can "zoom in" to see increasing detail.
