Journal of Geophysical Research, B10— By studying the size, shape, and age of terraces, one can determine the geologic processes that formed them. By late Eocene time, erosion had produced the only widespread surface of low relief developed in the mountains.

Highlights

Number of times cited: Close article support pane. The ages of incision and flooding aggradation can have different interpretations for each fluvial system, where each region may respond independently to external variation.

The response of erosional landscapes to Quaternary climate oscillations is recorded in fluvial terraces whose quantitative interpretation requires numerical ages.

During Laramide tectonism, streams eroded the sedimentary cover, exhuming pre-Mesozoic surfaces and beveling Precambrian rocks. The previous floodplain is therefore abandoned and becomes a river terrace.

Recommendations

Evaluation on geologically short time scales 10 3 5 a can reveal much about the relatively shorter climatic cycles, [5] local to regional erosion, and how they could drive terrace development. Terraces record natural, periodic variations driven by cycles such as the Milankovitch cycle.
