Contemporary Geoglyphs by Jocelyn Duke

This is an old photo from my time in Brasília that just got featured in this set of pictures from Moon Valley & Chapada dos Veadeiros National Park. I hadn’t thought about Chapada dos Veadeiros in a while. It’s a magical place. Very remote. Very pure. It was a great trip.

Tassili n’Ajjer National Park covers 72,000 square kilometers (27,800 square miles) in southeastern Algeria. Part of the Sahara Desert, the park has a bone-dry climate with scant rainfall, yet does not blend in with Saharan dunes.

This image is made from multiple observations by the Landsat 7 satellite in the year 2000. It uses a combination of infrared, near-infrared, and visible light to better distinguish between the park’s various rock types. Sand appears in shades of yellow and tan. Granite rocks appear brick red. Blue areas are likely salts.

The earth splits and spills at Puʻu ʻŌʻō in Kīlauea.
