As a geologist, and an enthusiastic traveler and hiker, I am continuously curious about how landscapes form and how our environment shapes human history.

Ancient Metals and Ancient Mines – Part 1

Rich deposits of metals, created by the dynamic geologic environment that built the rugged Andes Mountains, became intertwined with Andean cultures in the New World. The Incas and their ancestors created metal products primarily for aesthetic uses and for religious goods. This contrasts with Old World cultures, where the emphasis was on the mechanical properties of metals -- strength, hardness and sharpness—for tools and weapons.

Deep Time and Geologic Time Scales

Geologic time scales, which show a chronological sequence of events that have occurred during Earth’s history, become more or less embedded in the brains of geologists. As for other people – probably not so much. Having a rough idea of this history and familiarity with a few names, however, will be helpful if you like to think about natural history, and especially geology topics...

A US Geology and Art Tour

The US Geological Survey produces maps that are works of art, as well as highly informative cartography. Meticulously hand drawn by artists, many of these maps can be appreciated for their visual appeal, even if you don’t delve too deeply into the details of rock units, faults and folds. One of my all-time favorites is the "Geologic Map of the United States" published in 1974.
