Down to Earth With marine geoscientist Harold Tobin

As a boy growing up on the East Coast, Harold Tobin loved being outdoors but was not all that excited by geology or the region’s ancient rocks. But the catastrophic eruption of Washington state’s Mount St. Helens in 1980, when Tobin was 15, and the notion that tectonic plates must be moving beneath the Pacific Northwest, captured his imagination. A few years later, while a student at Yale University, he volunteered as a summer intern at Mount St. Helens National Volcanic Monument. That experience, along with his undergraduate curriculum, convinced Tobin to become a geologist.

Travels in Geology: Las Vegas: The scenery beyond the slots

Beyond the Strip lie southern Nevada’s craggy limestone peaks, colorful sandstone canyons, and enormous conservation areas that, despite the searing desert heat, harbor a tremendous diversity of plants and wildlife. From soaring summits and graceful bighorn sheep to prehistoric petroglyphs, this desert oasis has a lot to offer the geo-minded traveler.

Getting there and getting around Las Vegas

McCarran International Airport is the main gateway for exploring Las Vegas and the surrounding area. Except for sights along the Strip, it’s necessary to rent a car to see the attractions described here. If you fly in, you can rent a vehicle at the airport or take a shuttle or taxi into the city and rent a car as needed. Although all of these sites are open year-round, the best times of year to visit are in the spring and fall. In winter, it’s not possible to hike high in the Spring Mountains due to snow, and in summer the valley heat can be stifling. There are currently no visitor facilities or infrastructure at Tule Springs National Monument, but you can catch a glimpse of the fossil beds near one of two National Park Service signs, one located at the intersection of Moccasin Road and Durango Drive, and the other where North Decatur Boulevard meets Horse Drive.

Arizona road hazard has surprising source

Blowing dust is one of Arizona’s deadliest weather-related hazards. Between 1955 and 2011, brownout conditions created by dust storms caused more than 1,500 motor vehicle accidents across the state, resulting in 157 fatalities and more than 1,300 injuries, according to a 2016 NOAA Technical Memorandum.

Denali's Asian dinosaurs

Paleontologists have long hypothesized that a land bridge between present-day Siberia and Alaska served as a gateway for fauna to migrate between Asia and North America during the Cretaceous, but they have unearthed little evidence that directly supports this idea. Now, researchers have found an Asian dinosaur track assemblage in North America, a discovery that backs the longstanding hypothesis.

Travels in Geology: Cones and craters in Flagstaff, Arizona

Few places in the country exhibit as many types of volcanic features — including jagged lava flows, crumbly cinder cones and the remnants of a towering stratovolcano — in as small an area as northern Arizona’s San Francisco Volcanic Field.

Travels in Geology: Sky-high adventure on Bolivia's Altiplano

Nestled between two ranges of the rugged Andes Mountains, the Altiplano is a vast, windswept plateau that stretches from southern Peru to northern Argentina, offering stunning, vividly colored vistas — from the snow-white crystals of the world’s largest salt flats and flocks of pink flamingos in a brick-red lake to the startlingly azure waters of Lake Titicaca.

Getting there and getting around Bolivia's Antiplano

Bolivia’s main gateway, El Alto International Airport (LPB), is located 13 kilometers southwest of the country’s capital, La Paz. It hosts regular, year-round flights to and from major destinations in South America, including Lima and Cuzco, Peru, Santiago, Chile, and Buenos Aires, Argentina, as well as connecting flights to Miami on American Airlines and Los Angeles, Washington, D.C. (Dulles) and Orlando, Fla., on Avianca. Several regional airlines, including Boliviana de Aviación (BoA) and Amaszonas, offer multiple flights daily from La Paz to Uyuni. The hour-long flight typically costs about $150 one way. We found the South American carriers to be extremely efficient; it’s important to arrive at the airport two hours in advance because the flights often depart early!
