Laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) was used to determine major and trace element concentrations in rock varnish samples from the Lahontan Range, near Fallon, NV and from a remote wilderness area near the San Juan R

Alpha particles have been measured coming from the surfaces of rocks covered with dark red-brown rock varnish, as well as rocks that appear to have little, if any, varnish. A pronounced peak at 5.3 MeV indicates the presence of 210Po, a short-lived n

Preliminary research on striated clasts from a variety of depositional environments suggests that scanning electron microscopy (SEM) of striated clasts of varying lithology in diamictons may prove useful in interpreting a glacial origin. Evaluating w

The Spring Mountains are located in southern Nevada and lie along the western margin of the Las Vegas Valley. A diamicton located approximately 2,590 m (8,500 ft) above sea level in the Spring Mountains contains numerous striated limestone clasts ran

Instructors in undergraduate science classes often teach skills and techniques by creating exercises that ask rather specific questions. Numerous authors have pointed to the need to help students develop quantitative skills using inquiry-based learni

Effective discharge is defined as the streamflow responsible for transporting the most sediment over the long term. Since the stream channel is a product of material that is transported by the stream, the effective discharge is interpreted to be the

Students generally leave their introductory geoscience classes with the notion that streams behave like conveyor belts wherein all flow regimes contribute more or less equally to the work done in the transportation of sediment. This view ignores both
