Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

Carbonates are ubiquitous, forming in a variety of settings including caves, soils, the oceans,
during burial from hydrothermal fluids, and along faults. U‐Pb dating of carbonates is …

We present a user‐friendly and versatile Monte Carlo simulator for modeling profiles of in
situ terrestrial cosmogenic nuclides (TCNs). Our program (available online at …

The correspondence between seismic velocity anomalies in the crust and mantle and the
differential incision of the continental-scale Colorado River system suggests that significant …

Accurate models for the incision of the Grand Canyon must include characterization of
tectonic influences on incision dynamics such as active faulting and mantle to surface fluid …

The uplift and denudation of the Colorado Plateau is important in reconstructing the
geomorphic and tectonic evolution of western North America. A Late Cretaceous (64±2 Ma) …

The Grand Canyon is one of the most dramatic features on Earth, yet when and why it was
carved have been controversial topics for more than 150 years. Here, we present apatite …

Abstract The Cradle of Humankind cave sites in South Africa preserve fossil evidence of four
early hominin taxa: Australopithecus africanus, Australopithecus sediba, Paranthropus …

The timing of formation of the Grand Canyon, USA, is vigorously debated. In one view, most
of the canyon was carved by the Colorado River relatively recently, in the past 5–6 million …

Abstract The Colorado River system in southern Utah and northern Arizona is continuing to
adjust to the baselevel fall responsible for the carving of the Grand Canyon. Estimates of …
