SP-399 SKYLAB EREP Investigations
Summary
FIGURE 3-3.-Southwestern San Joaquin
Valley, California, June 3, 1973. Land use strata (fig. 3-3(b)) are
correlated fairly well with the boundaries between the valley basin
and valley basin rim soils and with the boundaries between the
alluvial and bedrock soils (fig. 3-3(a)). However, the boundary
between the valley basin rim soils and the alluvial fan soils does
not correlate with any of the agricultural land use strata
boundaries. (a) Natural color S190A photograph (SL2-04-121).
Boundaries between major soil types have been transferred from a soil
map. Red crosshatched areas represent the valley basin soils, blue
hatching shows the valley basin rim soils, and yellow hatching
correlates with the alluvial fan soils. Unhatched areas represent
soils that developed on bedrock material. (b) False-color-infrared
S190A photograph showing land use strata (SL2-03-121).
