Glacier beds get slipperier as sliding speed increases
“As a glacier’s sliding speed increases, the bed beneath the glacier can grow slipperier, according to laboratory experiments conducted by Iowa State University glaciologists.
They say including this effect in efforts to calculate future increases in glacier speeds could improve predictions of ice volume lost to the oceans and the rate of sea-level rise.”

Laser Scanner Techniques to Monitor Glaciers
“The Ossoue glacier in the Vignemale massif (3,298 m) is currently the longest and second largest of the Pyrenees (1,400-m length, 50-ha area), and the only one presenting glacier tongue morphology. We describe 50 MHz ground penetrating radar (GPR) and laser scanner surveys from which we assess the current state and dynamics of the glacier. ”

Mount Kenya’s Vanishing Glaciers
“It’s important to know two things about the adventure that followed, which Benuzzi chronicled in his book, “No Picnic on Mount Kenya.” First, Benuzzi did manage to escape the camp and climb to the summit of the mountain’s third-highest peak. Second, when Benuzzi came back down, after 18 days on the mountain, he apparently felt so rejuvenated — as if he had absorbed enough beauty to sustain him — that he decided to sneak back into the camp and picked up his life again as a prisoner. The mountain was that large and impressive, that sublime. ”
