CLIMBING — Northwest climber/photographer Alan Kearney has an ongoing project to photograph Cascades glaciers from the same spot he photographed them on climbing trips decades ago.
As you might expect, having read anything about climate change in the past few decades, the glaciers show considerable shrinkage. See one of his stories and photo comparisons here.

PARKS – A hanging glacier that’s captivated hikers, climbers and tourists for as long as humans have explored Jasper National Park, Alberta, broke loose from its precarious perch on Mount Edith Cavell this month, according to a story with photos at Examiner.com.
The crash of ice created a tsunami from the Cavell Pond below that gushed out, ripping up a corner of the popular trailhead parking area and trails.
Luckily, the event happened early in the morning on Aug. 10 before visitors had arrived. No one was injured.
While glaciers are slowly disappearing around this globe, centuries of ice were instantly lost in this event. Park officials estimate 50-60 percent of Ghost Glacier crumbled away.

MOUNTAINS — This 6-minute sequence of excellent aerial photography documents the splendor of the mountains in Canada just north of Washington and Idaho as well as what some of these precious places could look like without protection.
Those of you who hike, paddle, climb and ski in the West Kootenays and East Kootenays will enjoy these images — titles included — of the Selkirks, Purcells, Rockies, Valhallas, Kokanee Glacier, Jumbo, Flathead, Bugaboos and the Coal Mines

CLIMATE CHANGE — On the heels of a report on the decline of glaciers on Mount Adams, a scientist in Olympic National Park says the Olympic Peninsula's glaciers have shrunk by an average of 15 percent since the 1980s, with one completely disappearing.
Ferry Glacier, one of the 60 largest at the park in 1982, disappeared from its rocky niche in the Bailey Range, according to the Associated Press.
Olympic National Park physical scientist Bill Baccus says another glacier, Lillian, has “virtually disappeared.”
Baccus has been studying the park’s 311 glaciers in detail since 2010. He says there are more glaciers now because larger ones have broken up. In 1982, researchers found 266 glaciers.
The most recent study found that Blue Glacier — the largest one — has lost 18 percent of its mass since 1982.
He says the average air temperature in the Pacific Northwest has gone up 3 degrees Fahrenheit since 1920.
CLIMATE CHANGE — In the first comprehensive study of its kind, a Portland State University study has found Mount Adams' 12 glaciers have shrunk by nearly half since 1904 and are receding faster than those of nearby sister volcanoes Mount Hood and Mount Rainier.
Mount Adams, 54 air miles from Yakima, is another sign of gradually warming temperatures that — if continued as expected by researchers — will mean significant problems for the water-dependent Yakima Valley, according to reports by the Oregonian and the Associated Press.
The study lends urgency to an earlier federal report that shows the water content of Cascade Mountain snowpacks could dwindle by as much as 50 percent by the 2070s.
The latest work on glaciers on the 12,276-foot Mount Adams by a Portland State University geology professor and a student team was based on aerial photography, geographic information system mapping, buttressed by historic photos taken by hikers.
The results show Adams' glaciers have melted away 49 percent of their coverage area since 1904.
Over generally the same time period Mount Rainier's glaciers lost 24 percent of coverage area and on Mount Hood the decline has been some 32 percent.
Some scientists suggest Adams gets less moisture because it is just to the east of the Cascades crest.
