New Magnetic and Radiometric Surveys Provide Raw Data for Interior Mineral Exploration
The Alaska Division of Geological & Geophysical Surveys is publishing two new airborne magnetic and radiometric surveys—one for the White Mountains north of Fairbanks and one near Eagle in the eastern Interior.
‘Remarkable Groove’ Slides Gold into Alaska
Over millions of years, the Tintina Fault has moved gold-bearing rocks from Canada into Interior Alaska. The Yukon River, as it enters Alaska, somewhat follows the trace of the Tintina Fault.
Dirty Glaciers All Over the World
Adding dirt to ice makes it darker, which can help it absorb more sunlight. About one-quarter inch of rocks on top of glacier ice acts like a black tarp, melting the glacier faster. If the rock coating is thicker, which is often the case, it acts as insulation.
Sifting Volcano Paydirt to Help Forecast Eruptions
Because people live on the slopes of Alaska volcanoes and thousands more fly through their blast zones each day, scientists want to forecast eruptions with more precision.
The Thin Line Between Alaska and Canada
Marked by metal cones and a clear-cut swath twenty feet wide, Alaska’s border with Canada is one of the great feats of wilderness surveying.
Students’ 3D Model Illustrates Decline of Alaska Glacier
The model represents the terminus, or end tip, of the Mendenhall Glacier, located a few miles east of Juneau’s northern suburbs.
Oldest Rock in Alaska is Near Iditarod
While gliding along a trail that had just felt the imprint of 2,000 dog feet, Bob Gillis skied over to a curious-looking rock that jutted from the snow…
Alaska Taking Shape Near Yakutat
The relentless advance of Hubbard Glacier takes center stage in Yakutat, but the area surrounding the town is one of the world’s great examples of geology in action.
Jabbing Sensors into the Denali Fault
The Denali Fault is a weak spot in Earth’s crust that has maintained a frown across the middle of Alaska with its continual jerky movement. Ten scientists are performing fieldwork here, where they are driving 400 seismometers into frozen soil.
