Getting there and getting around Idaho

If you’re interested in a trip down the Main Salmon, you have two options: put a trip together yourself, or hire a professional outfitter to take you.

Travels in Geology: Rafting the Salmon River through the Idaho Batholith

Rafting down the Main Salmon River, which courses north and then west across northern Idaho, takes you by Precambrian metamorphics and the granites of the Idaho Batholith. Six to eight days later, your trip concludes as you float past what was once the edge of North America, and over former island arcs sutured onto the continent during the Mesozoic.

Fieldwork among the pixels: Virtual and augmented reality diversify geoscience education

Students going out into the field to gain hands-on experience and mapping skills is a time-honored tradition in geology. Now, teachers are using virtual and augmented reality technology to bring the field to the students.

Data-driven discovery reveals Earth's missing minerals

New discoveries in mineralogy, one of the oldest human endeavors, are arising from a new sort of mining—data mining. Mineralogists are applying statistical models and data science techniques to reveal previously unseen patterns and clues hidden in mineralogical databases, and to find undiscovered minerals.

Oceanic crust in all its glory

Our loop drive through the high Hajar Mountains boasted excellent exposures of every oceanic crustal layer. One good exposure of the sequence of mantle rocks is found in the hills surrounding Oman’s capital city Muscat. They consist of a variety of peridotite called harzburgite, which is the pyroxene-depleted residue left behind after basaltic magma is extracted. That extracted magma forms the oceanic crust, whose characteristic rock sequence is, from bottom to top: 1) dark, layered gabbro overlain by massive gabbro (the intrusive equivalent of basalt that comprises solidified magma chambers); 2) sheeted basaltic dikes (the conduits that transported lava from the magma chambers up to the ocean floor); and 3) bulbous pillow lavas, which form when basalt erupts directly into seawater.

Getting there and getting around Oman

Oman’s main gateway is Muscat International Airport (MCT), which offers service to most major Middle Eastern and European cities. There are no direct flights to Oman from North America; it’s usually most convenient to fly through Dubai, Doha, Bahrain or a major European city. Emirates, Qatar Airways, Gulf Air, Oman Air and Turkish Airlines are among those that offer connecting service.

Travels in Geology: Northern Oman: Stunning canyons, towering dunes and the world's largest ophiolite

The small, politically stable sultanate of Oman hosts the world’s biggest and most intact ophiolite — a rare slice of oceanic crust emplaced on land — as well as stunning canyons, turquoise swimming holes, lush palm oases, Bronze Age tombs, endangered sea turtles and endless fields of sand dunes.

Slumgullion: Colorado's natural 'lab' offers insights into landslides worldwide

In southwestern Colorado, a centuries-old landslide (first identified as such in 1883 by an infamous prospector and purported cannibal) is offering geologists an ideal laboratory to study slow-moving slides.

From farm to filter: Restored wetlands remediate nitrogen pollution

The early 20th-century invention of a nitrogen-fixation process revolutionized agriculture and made it possible to feed the planet’s growing population. But nitrogen runoff is polluting our waterways and suffocating aquatic life. Now, researchers looking for ways to reverse that trend are turning farmland into wetlands to filter nitrogen from streams and rivers.

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.
