Travels in Geology: Tracking African animals and deranged drainages across the Kalahari

The Okavango Delta, a major river delta in the middle of the dry Kalahari, and thundering Victoria Falls, a day’s drive away, may seem unrelated. But to a geologist, they are inextricably linked by hydrologic changes that have swept across southern Africa in response to subtle tectonic movements and major Pleistocene climate fluctuations.

Getting there and getting around Kalahari

There are three gateway cities to the Kalahari, all of which are at least a day’s drive from the Okavango Delta. Although it’s the farthest (about 12 hours away), the O.R. Tambo International Airport (JNB) in Johannesburg, South Africa, is the region’s largest and often has the best airfares and car-rental rates. Two closer alternatives, each about an eight-hour drive away, are Botswana’s Sir Seretse Khama International Airport (GBE) in Gaborone and Namibia’s Hosea Kutako International Airport (WDH) in Windhoek. Maun (MUB) is Botswana’s primary tourist hub and the delta’s main service town. Most accommodations there provide a free minibus transfer from the airport.

Benchmarks: June 1977: First Excavations at Nebraska's Ashfall Fossil Beds

In the spring of 1971, paleontologist Mike Voorhies was mapping rock exposures on a farm in northeastern Nebraska when he wandered into a small ravine that recent heavy rains had swept clean of debris. High on the gully wall, a change in the color of the rock caught his eye, so he decided to scramble up and take a closer look.

Down to Earth With: Planetary geologist James W. Head III

In the late 1960s, as James W. Head III was finishing his graduate degree in geology at Brown University in Providence, R.I., he decided one day to take a look at a college placement annual, a phone book-like publication that listed prospective employers according to the types of jobs they had available. When Head looked up geology in the index, he saw several consecutive pages of related listings, as well as one separate page number. Curious about the outlier, Head flipped to it — and never looked back. Covering that entire page was a photo of the moon, a D.C.-area phone number, and a single line of text: “Our job is to think our way to the moon and back.”

Travels in Geology: Easter Island's enduring enigmas

Easter Island, a lonely island in the southeastern Pacific Ocean, is steeped in mystique — and not just for its famous, perplexing statues and controversial story of societal collapse. How the island formed has also baffled geologists for decades.

Getting there and getting around Easter Island

Easter Island has just one gateway, tiny Mataveri International Airport (IPC), to which only one airline, the Chilean carrier LATAM, offers regular service. This includes one flight weekly from Tahiti, as well as daily service from Santiago, a five-hour flight. Airfares are high, ranging from about $400 to $1,500 round trip. The island’s unusually long runway once served as an emergency U.S. space shuttle landing site; today, it allows LATAM to land large Boeing 787s there, a rarity among small islands.

Travels in Geology: The Dead Sea Rift: Salty soaks and ancient earthquakes in a storied land

The Dead Sea and the surrounding area boast impressive geology — from ancient earthquake records to pillars of salt — that bears witness to civilization-shaping stories.

Getting there and getting around the Dead Sea rift

Most flights into Israel from the U.S. and Europe go through Ben Gurion International Airport (TLV), located 19 kilometers south of Tel Aviv. The most flexible and convenient option for getting to and from the airport and for exploring the region is to rent a vehicle; the airport and downtown Tel Aviv offer many rental options. Cars drive on the right, and road signs are marked in Hebrew and English. From the airport, the Dead Sea is about a three-hour drive (170 kilometers).

Getting there and getting around Patagonia

Southern Chile has two main gateways, the homey town of Puerto Natales, a 1.5-hour drive from the national park, and Punta Arenas, a small city about 4 hours’ drive to the south. Of the two, Punta Arenas (PUQ) has the larger airport, which hosts regular year-round flights from Santiago on LATAM and Sky Airline, an efficient regional carrier, plus occasional flights from Puerto Montt in Chile’s beautiful Lake District. Flights to Puerto Natales (PNT) only operate during the summer season. There are no direct flights from the U.S. to this region.
