Slipping point: Snow scientists dig in to decipher avalanche triggers

Scientists are studying avalanche triggers to understand how, where and when avalanches may occur. They’re starting to get a handle on the structure of packed snow and how avalanches fail and propagate.

How deep do the Alps go?

Continental crust was long thought to be too buoyant to subduct into the mantle, unlike denser oceanic crust, which descends into the mantle in many locations around the world. But the discovery of coesite — a type of silica formed at the extreme pressures present in subduction zones — in the Alps in 1984 challenged that long-held idea. Seismic evidence backing up claims that continental crust has indeed been subducted beneath the Alps has been scant, however, until now.

Wormholes may limit landslides

When Emma Harrison, a graduate student at the University of Pennsylvania, began digging trenches in the Luquillos Mountains of Puerto Rico to study how the soil mantle responds to rapid changes in erosion, she couldn’t help but notice that the thick soils were chock-full of wriggling worms. Intrigued by the worms’ abundance and prodigious activity at her field site, Harrison wondered whether their presence could be influencing weathering and erosion in the Luquillos.

Benchmarks: April 12, 1934: Record winds buffet Mount Washington

When Jeff Masters was 5 years old, a brutish gust of wind knocked him flat. The incident transpired on top of New Hampshire’s Mount Washington, a place that has long fascinated Masters — now a meteorologist and the founder of the popular forecasting site Weather Underground.

Benchmarks: August 24, 1873: The Mount of the Holy Cross is found, photographed and mapped

The rumors had persisted for decades, some said for centuries. Deep in the Colorado Rockies was a mystical mountain. Upon the face of a towering peak rose a massive cross, formed by snow accumulating in two huge cracks. In his 1868 book, “The Parks and Mountains of Colorado: A Summer Vacation in the Switzerland of America,” journalist Samuel Bowles wrote, “It is as if God has set His sign, His seal, His promise there — a beacon upon the very center and hight [sic] of the continent to all its people and all its generations.”

Travels in Geology: Precipitous peaks and dunes in Colorado

Majestic snow-capped “fourteeners,” alpine meadows carpeted in wildflowers, pristine mountain lakes. These are the images most people associate with Colorado. One of the best places to experience this rugged wilderness is Rocky Mountain National Park in the northern part of the state.

Travels in Geology: Climbing Mount Kilimanjaro: From parasitic cones to equatorial glaciers

Tanzania’s Mount Kilimanjaro is the world’s tallest mountain that climbers can reach without technical means. The author decided to try it for herself, and brought back a lifetime of memories and dozens of photos of parasitic cones, equatorial glaciers, lava outcrops, volcanic vents and scenery to die for.

Celebrity climb

One billion people are without access to clean water today. When glacial deposits like the one atop Kilimanjaro melt away, that number will increase, some researchers say. To raise awareness about what some people are calling the global clean water crisis, a team of celebrities climbed Mount Kilimanjaro in January in the “Summit On The Summit.”

Travel specs

Booking a climb up Kilimanjaro can be a little daunting. I recommend first figuring out your climbing details and then figuring out how you will get to the mountain. Climbs are offered year round, but weather-wise, it is best to go in January and February or September and October. There are six main climbing routes up the mountain, and they all offer unique sites and spectacular views. Besides differing in scenery, these routes vary in physical difficulty, length (between five and 10 days), accommodations and prices. Prices range from $1,200 to $5,000 per person, with costs covering food, accommodations, park fees, transportation and rescue service, should it be necessary. Moreover, all of the agencies have their own supply of gear in case you are missing anything. For a list of respected, well-known tour operators, check out the “Climb with a Partner Company” page on the Kilimanjaro Porters Assistance Project Web site (www.kiliporters.org/index.php).
