On the Web: Personalizing drought data with digital tools

One of the hardest parts of hazard mitigation is communicating risk to the public. With drought, people feel the heat while it’s happening but understanding how the current drought fits into past trends — and their implications for the future — is harder to grasp. Now, several online tools are available to help the public and decision-makers look at drought data.

Tackling "Boundary Faults" across the Alaska-Yukon border: A report from the field

Our two dusty trucks roll across the airstrip, casting long, late-May shadows down the runway. We spot our colleagues from the Yukon Geological Survey and realize we’ve found the right place after an exhausting 12-hour drive from Anchorage punctuated by several U-turns to find the right unmarked access driveway off the Alaska Highway at the south end of Kluane Lake. The evening air is crisp, and the towering peaks to the south are capped with snow.

Map provides clues to natural protection of U.S. coastal communities

Devastating storms like Hurricanes Sandy and Katrina have left many coastal residents wondering how to protect life and property from future catastrophes. In a study published this week in Nature Climate Change, researchers suggest the best protection from storms and rising sea levels in the U.S. may entail a combination of engineering and conservation.

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.”

Mobile mapping with lidar hits the road

About a decade ago, Light Detection and Ranging technology, also known as lidar, burst onto the geoscience scene. The tool was quickly adopted by researchers, from archaeologists and geomorphologists to seismologists and atmospheric scientists.

By mounting lasers and detection and positioning instruments on an airplane or satellite, researchers could map everything from Mayan ruins lost beneath thick jungle canopies to erosion along shorelines to the structure of particulate plumes emitted from power plants to the topography of entire countries.

Cold case files: Forging forensic isoscapes

In November 2006, someone left a badly beaten man at a hospital in Gwent, South Wales. The victim was severely injured and died shortly thereafter without revealing his identity. All the Gwent police knew about the John Doe was that he was Asian, or of Asian descent, and possibly Vietnamese. There was no record of him entering the country. His fingerprints provided no further information on his identity. The trail went cold.

Down to Earth With: John 'Jack' Reed Jr.

Geologist Jack Reed spent his career studying rocks the most strenuous way someone can — by climbing them. During much of his 47 years with the U.S. Geological Survey, Reed clung  to rock faces in Alaska, Wyoming and Colorado, while creating geologic maps of North America’s tallest mountain ranges. Along the way, he published dozens of books for climbers and hikers on the geology of places like the Tetons in Wyoming, Seneca Rocks in West Virginia, Shenandoah National Park in Virginia and, most recently, “Rocks Above the Clouds: A Climber’s Guide to Colorado Mountain Geology.” Shortly before his latest book hit the shelves, Reed took some time out of his busy retirement schedule to speak with EARTH contributor and fellow climber Mary Caperton Morton.
