In 2010, two of the study's authors—David Shuster of UC Berkeley (left) and Yosemite Park geologist Greg Stock (right)—collected rock samples from the rim of Yosemite Valley, where the granite has eroded only slowly over the last 50 million years. In the distance is the upper Merced River valley. Former UC Berkeley graduate student Johnny Webb is at center. Credit: Kurt Cuffey, UC Berkeley

River erosion can shape fish evolution

Broad surfaces called terraces preserve ancient river floodplains and landscape history up to hundreds of meters above the Fortymile River, a tributary of the Yukon River, in eastern Alaska. Researchers from the USGS, the University of Vermont, Purdue University and Utah State University publish definitive support that increases in sediment deposited to oceans from river erosion coincide with dramatic changes in glacial cycles.

The two accumulation phases of the Mediterranean salt layer during the Messinian Salinity Crisis. In the first phase, salt accumulated in a Mediterranean Basin filled with brine; in the second phase, salt accumulated in a Mediterranean completely isolated from the Atlantic Ocean, as a result of the significant drop in sea level in the western and eastern Mediterranean sub-basins. © Giovanni Aloisi
