Distinguishing Features

In cultural terms, the Southwest has never been satisfactorily defined. This is particularly true of the southern boundaries. Archeologists usually include the territory occupied by the groups we term Anasazi, Hohokam, Mogollon, and Patayan; it is this area that will be considered here.Physiographically (Atwood 191+0; Darton 1925; Fenneman 1931), the northern and eastern parts of this area belong primarily to the Colorado Plateaus Province; the southern and western parts comprise a portion of the Basin and Range Province. Physiographers subdivide these major provinces into lesser units having more significance for the archeologist. The Colorado Plateaus Province is marked primarily by high mesas and plateaus underlain by nearly horizontal strata of strong, cliff-producing rocks locally covered by volcanic features or domed by igneous intrusions. This extensive area is drained largely by the Colorado River and its tributaries. Among the distinguishing features are the hundreds of deeply entrenched canyons and great retreating cliffs or escarpments.

Seismic Sections

Seismic sections from COCORP’s 1982 survey from the eastern Basin and Range to the Colorado Plateau of central Utah exhibit distinct cutoff times after which reflections are rare to nonexistent. In the eastern Basin and Range, this cutoff time is approximately 11 s (33 km), but beneath the central Colorado Plateau it exceeds 15 s (45 km). These depths appear to correspond to the base of the crust (Moho), with the lack of reflections from greater depths indicating mantle homogeneity. In general, absence of deeper reflections may be due either to geologic homogeneity or to lack of signal penetration. COCORP line 3 in the Colorado Plateau‐Basin and Range transition zone shows that variations in penetration are significant. On line 3 few reflections are evident below the structurally complex sedimentary cover, which extends to only 4 s (8 km), and virtually none are identifiable later than 7 s (21 km). Lateral variations in the temporal decay of source‐generated energy, together with estimates of corresponding ambient noise levels, infer that limited signal penetration, rather than geologic homogeneity, causes the lack of subsedimentary reflections within the transition zone. Deep reflections, if any, from beneath the westernmost Colorado Plateau appear to be masked by unusually high local environmental noise. In contrast, continued decay of source‐generated energy at traveltimes significantly greater than Moho arrival times within the Basin and Range and Colorado Plateau suggests (though it cannot confirm) that the underlying mantle is seismically transparent. Variations in signal penetration, such as those documented here, severely constrain interpretations of nonreflective zones in deep reflection data and should be a standard estimation in any interpretational procedure.
