Getting there and getting around the Causses

Toulouse is the best gateway to the Causses region. Toulouse-Blagnac Airport hosts plenty of flights to connecting cities in Europe, but no direct flights from the United States. Rent a car at the airport and head north to explore the region. The main highway going north to the Causses is well maintained, with fueling stations along the way that offer everything a traveler might need, including showers. Figuring out how to pay for gasoline was tricky — but that’s part of the adventure of travel.

Travels in Geology: Underground awe in France: The caves of the Causses

The Causses du Quercy region in south-central France has been transformed into a karstic wonderland by the slow dissolution of limestone. The resulting caves, which served as shelters for early humans who left their bones, tools and art for us to ponder, are both geologically and paleoanthropologically fascinating.

Geomedia: Books: "Half-Earth" is only half-compelling

Edward O. Wilson, professor emeritus and honorary curator in entomology at Harvard, is a scientist of acclaim and renown, a naturalist and experimentalist who has made astounding discoveries about the natural world. These discoveries range from small details about ant communication to much larger ideas related to sociobiology, the co-evolution of genes and culture, island biogeography and biophilia, for example. His work is widely known, in large part, because he’s a talented and prolific writer, and he has twice won the Pulitzer Prize.

Geomedia: Books: "Aerial Geology": A stunning and informative addition to any coffee table

My fellow EARTH Magazine contributor Mary Caperton Morton is the author of “Aerial Geology,” a beautiful and massive tome that profiles a hundred geologically interesting locations across North America. Mary was kind enough to forward me a copy for review, and I was delighted to flip through its gorgeous pages. It’s a visual feast, with a mix of satellite imagery, aerial photography and ground-based photos. Each site is allotted two to four pages for photos and Mary’s written descriptions, which are sometimes augmented by excellent schematic illustrations by the talented Kat Cantner, the illustrator for EARTH and the American Geosciences Institute (which publishes EARTH).

Travels in Geology: The diverse geology, landscapes and whiskys of Scotland's Southwestern Islands

For the geologically minded traveler, the Scottish isles of Arran and Islay showcase a suite of interesting rocks and landscapes, a wealth of cultural and recreational opportunities, and Scotland’s second-finest product (after the geology): single malt whisky.

Getting there and getting around Scotland's Southwestern Islands

Ferry service to Arran and Islay is the primary way to access the islands from the Scottish mainland. Caledonian MacBrayne (“CalMac”) offers a “hopscotch” ticket package that goes from Ardrossan (close to Glasgow) to Brodick (Arran), across the Kintyre Peninsula, to Port Ellen (Islay), and then back to Kintyre, all on your own schedule, for £150, including ferrying your rental car. (We brought a rental car with us from the mainland, in the interest of being able to access outcrops where and when we wanted, but each island offers a municipal bus service as well.) Reserve a space for your car on the ferry during peak tourist times. Also, be prepared to be stuck on an island for a bit (usually not more than a few hours) if the weather turns.

Geomedia: Books: Looking at the World Anew in "The Planet Remade"

Geoengineering, the deliberate large-scale modification of environmental processes on Earth, is often proffered as a solution to climate change. The transfer of carbon long sequestered in geologic repositories to the atmosphere has raised greenhouse gases to levels unprecedented in the history of our species. As a result, the average surface temperature and the heat content of the oceans have both increased.

Travels in Geology: Geo-diversity and geologic history in the North West Highlands of Scotland

The complex rocks of the North West Highlands of Scotland —which span two-thirds of Earth’s history — include the oldest rocks in the United Kingdom, as well as some young, glacially sculpted landscapes. They also hold a prominent place in the history of geology.

Geomedia: Books: Exploring "The Worst of Times"

Every reader of this magazine knows something about mass extinctions. But few of us know as much as Paul B. Wignall, a professor of paleoenvironments at the University of Leeds in England who studies mass extinctions. In 1997, he co-authored with Anthony Hallam a scholarly volume titled “Mass Extinctions and their Aftermath.” Now, his first book aimed at a popular audience, “The Worst of Times: How Life on Earth Survived Eighty Million Years of Extinctions,” has been issued in paperback.
