Monuments, Megaliths, and Inca Builders

In the Andes Mountains of South America, the Incas and their ancestors invested enormous amounts of time and labor in the meticulous work of quarrying, transporting, and fitting together multi-ton stone blocks, or megaliths, for monumental construction projects..... The ancient Andean stonework is so impressive that many have found it difficult to believe that mere humans, who lacked draft animals and were using only stone-age tools, could be responsible for the construction.

Salt Ponds of Maras

Small salt ponds numbering in the thousands are arranged on steep mountain slopes near the city of Cusco, former capital of the Inca Empire, high in the Andes Mountains of Peru. Known as Maras, and originating from a saline spring, these salt ponds have been tended carefully since Inca times 500 years ago, and possibly for hundreds (or thousands?) of years before the Incas.

Ancient Ochre Mines Underwater

Evidence indicating where ancient people collected the valuable pigment red ochre thousands of years ago may seem like an unlikely combination with underwater archaeology – but that isn’t the case. Sea levels have been substantially lower than at present for most of human existence, so we know that many traces of our history are hidden beneath water.

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...

Red Rock Country on the Colorado Plateau

Grand Canyon, Zion, Arches, Canyonlands, and other national parks on the Colorado Plateau encompass some of the most spectacular scenery on Earth. Extending across the Four Corners region where the borders of Utah, Colorado, New Mexico, and Arizona meet...the landscape is sculpted into dramatic cliffs and arches, domes and towers, fins and hoodoos, mesas and buttes, slot canyons, and deeply carved canyons.
