What grows in arid, sandy soils? How do these soils become dust?
Many small organisms, such as bacteria and fungi, grow among the sand and silt particles in dry valley and desert soils. At the soil’s surface, these organisms often form biological webs (“microbiotic crusts”) that keep small sand...

Introduction
Dry wells improve stormwater drainage and aquifer recharge by providing a fast, direct route for rainwater to drain deep into underlying sediment and rock. Dry wells are most common in the western U.S. where clay or caliche layers slow down the natural drainage of water into...

Geologic maps have provided the key to finding new gold deposits in Nevada.
Defining the Problem
The western states contain many gold deposits (Fig. 1), and a zone of faulted sedimentary and igneous rocks in northeastern Nevada, known as the “Carlin” trend, is the most productive region in the...
