Geologists love to have a bird’s eye view of landscapes. They are helpful for all types of research - tracing active faults and identifying copper ore deposits among them. In this post there are two stories about geology fieldwork - one about earthquakes in Egypt and the other about copper in Chile, tied together by arid landscapes and helicopters.
El Niños, the warm phase of the El Niño-Southern Oscillation (ENSO) climate pattern, could be devastating for ancient Andean societies. Direct evidence of these events is scarce, but clever archaeological sleuthing has revealed details of event recurrence – and desperate measures taken by authorities to stop destructive flooding.
El Niño and La Niña weather patterns profoundly affect human societies – today, as well as during the past few thousands of years, especially in the strongly affected Peruvian Andes. Both are part of the climate pattern named the El Niño-Southern Oscillation (ENSO).
From maize-based chicha, or corn beer, in the Andes Mountains, to mead from honey in ancient Greece, and wine from grapes in Predynastic Egypt, fermented beverages have been a part of cultural rituals for many thousands of years. Celebrations that include copious amounts of alcoholic drinks and specially prepared foods have been widely practiced in numerous cultures over time.
Five hundred years ago the Inca Empire stretched across the Andes Mountains of South America, encompassing arid coastal deserts, snow-covered mountains, and humid rainforests.... Since the empire fell in the 16th century, there is something that no subsequent government ruling over this territory has successfully achieved.
One of the most spectacular mountain ranges on Earth is the Cordillera Huayhuash in northern Peru. These mountains were also the setting for "Touching the Void", the title of both a book and movie about a disastrous 1985 mountaineering expedition.
The jagged Andes Mountains of South America, the sculpted Red Rock country in the western US, the towering waterfalls of Yosemite Valley - and every other impressive landscape on Earth – have had their scenic beauty carved through weathering and erosion of rock. Over immense amounts of time .... landscapes are shaped.
What do lava flows in Hawaii, eucalyptus trees in the Andes Mountains of Peru, beehive-shaped ovens in Nevada, and a dog’s ticket to a veterinarian office for an emergency visit all have in common? I can explain.
High in the Andes Mountains, the archaeological site of Moray holds many mysteries. Starting with natural sinkholes, Inca builders lined a set of huge circular depressions with concentric terraces. Constructing Moray required tremendous engineering skill and thousands of hours of construction efforts, so why was it built?
The Incas were accomplished engineers who built long-lasting structures, from Machu Pichu on a ridgetop to the Inca Road system along the spine of the Andes Mountains. A sculpted landscape masterpiece that is less well known is a set of large circular depressions lined with concentric rings of stone-lined terraces. Named Moray and located on a high plain about 20 miles northwest of Cusco, these circles began as deep natural sinkholes with unstable slopes at the angle of repose.
