WINTER SPORTS — Massive avalanches have been triggered at Crystal Mountain Resort near Mount Rainier as ski patrollers try to mitigate the huge unstable snowpack and make the area safe. The slides are damaging facilities at the mountain.
DRIVING — Snow conditions are still dicey out there.
U.S. 2 over Stevens Pass has been blocked since this morning after an avalanche blocked four lanes of traffic at least four-feet deep with snow.
The Washington Department of Transportation estimated it could reopen the Highway by 1 p.m., but the latest report says crews are still working and gives no estimate on a time for reopening.
Highway 2 across Stevens Pass closed this morning due to a landslide that occurred just west of the pass.
The Washington State Department of Transportation closed the highway between mile post 58, near Scenic, to mile post 64.5 while workers clear the road of snow and debris and perform avalanche control work. They estimate reopening of the highway by 1 p.m. today.
Highway 2 is open between Leavenworth and Stevens Pass. Stevens Pass Ski Resort closed for the day due to the road closure, weather and avalanche conditions.
WINTER SPORTS — The avalanche that came down off Mount Jumbo on Friday and crushed a house in Missoula was human triggered, according to the Missoula Avalanche Center. This is an eye opener.
WINTER SPORTS — Several blog posts last week as well as my Sunday Outdoors section report about recent storms, unstable snow conditions and a spike in avalanche fatalities were both prophetic and out of date.
At least two more snow-goers died in Inland Northwest avalanches over the weekend:
The Kootenay Pass fatality involved a many in a party of four from Nelson. They were backcountry skiing in the Lightning Strike area, southwest of the highways yard at the top of the pass.
In both fatal accidents, other members of the parties were partially buried by the slides but were rescued.
The Idaho Panhandle Avalanche Center had posted a forecast on Friday rating the avalanche hazard in the Selkirks-Cabinet region as considerable ranging to high in wind-loaded aspects. The report noted that a human-triggered avalanche had been reported on Tuesday with no injuries.
The Canadian Avalanche Centre had issued a special warning for British Columbia last week, as a result of an extended dry period in late January and early February.
“That long drought left the surface of the snowpack in very bad shape,” said the centre's Karl Klassen. “Now the new snow is sitting on one of the worst weak layers we’ve seen in a few years.”
The weakness is one to two meters deep, resulting in very large avalanches when triggered, Klassen said.

WINTER SPORTS — The avalanche that killed a snowmobiler last weekend near Ketchum — while a woman survived even though she'd been buried for 90 minutes — is detailed in his video report from Sawtooth Avalanche Center.
It's short, instructive and worth watching in this period of winter weather that's spawned a rash avalanche accidents.
WINTER SPORTS — Recent weather is creating hazards. Be careful out there.
Massive avalanche in B.C. prompts warnings there and in Alberta
The Canadian Avalanche Centre issued a high-hazard warning for British Columbia and Alberta after learning of a massive slide on Wednesday near Fernie, B.C., destroyed 200-year-old trees and ran past historical avalanche boundaries.
WINTER SPORTS — Snow that piled up in Western mountains after snow-drought conditions in January has created hazards that have caused a spike in avalanche fatalities among skiers and snowmobilers.
The nine deaths from avalanches across the Western U.S. in the past 11 days have put a halt to what had been the least-deadly season for avalanches in 16 years.
An avalanche near Ketchum, Idaho, on Sunday buried four snowmobilers, killing an Idaho man whose wife survived being buried under the snow for about 90 minutes, officials in Blaine County said.
Two Wisconsin men were killed Saturday in a Colorado avalanche while backcountry skiing.
Five people were caught in avalanches over the weekend in Montana.
On Feb. 11, an avalanche in the Wallowa Mountains of eastern Oregon killed two backcountry skiers and seriously injured two others.
For most of the winter, primarily because of the dramatic lack of snow in the Western mountains, only six people had been killed in avalanches, according to data from the National Avalanche Center in Bozeman. This was the lowest number through the first week of February since at least the 1998-99 winter season.
However, with the nine deaths in the past week or so, the winter's total is now 15, which is about average.
“A lot of snow in a little amount of time, you get avalanches,” said National Weather Service meteorologist Chris Burke in Seattle.
On average, about 28 people a year die in avalanches in the U.S., according to Brian Lazar of the Colorado Avalanche Information Center. He said the deadliest seasons on record were 2007-08 and 2009-10, when 36 died in each of those winters.
When avalanche deaths were first tracked starting in the 1950s, an average of four people died each year in avalanches.
But the growth in winter backcountry recreation on skis, snowboards and snowmobiles has led more people into the potential hazards.
With more heavy snow falling in portions of the Inland Northwest — notably the North Cascades — backcountry travelers should be on high alert and willing to bail out for a backup plan.
WINTER SPORTS — Friends of the Idaho Panhandle Avalanche Center are sponsoring an avalanche education scholarship in memory of Doug Abromeit, a Sandpoint native who was instrumental in starting the National Avalanche Center. Abromeit died last fall.
” We will send one student a year to a Level 1 avalanche class under the Doug Abromeit Avalanche Scholarship,” said Kevin Davis of the IPAC based in Sandpoint. ”Doug was born and raised in Sandpoint and his family still resides here. Doug retired from the Forest Service in 2011, last stationed in Ketchum, Idaho.”
The scholarship will be introduded at a special public program on Friday (Jan. 17), 4:30 p.m., at the Caribou Room in the Day Lodge at Schweitzer Mountain Resort. Several presenters will highlight Abromeit’s contributions to avalanche education, the history of avalanche control in the USA, and development of the National Avalanche Center and the Idaho Panhandle center.
WINTER SPORTS — The avalanche that killed a snowmobiler riding in the Gallatin Mountains on New Year’s Day – the first Montana avalanche death in more than a year – was somewhat of an anomaly, according to an expert that spoke with the Billings Gazette.
“Most avalanches happen when people are on the slope,” said Doug Chabot, of the Gallatin National Forest Avalanche Center. That can happen when a snowmobiler is riding across a hill or uphill, or when a skier or snowboarder is carving turns downhill.
But the avalanche that killed 46-year-old Burton Kenneth Gibson of Bozeman and partially buried another rider was what’s called a remote trigger avalanche – when a slide is caused by collapsing of the snowpack from what may look like a relatively flat or safe area.
The story by outdoor reporter Brett French is instructive to snow goers.
“When there’s a weak layer in the snowpack, in order to get an avalanche we need that weak layer to collapse,” Chabot said.
He said the unstable snowpack found in the mountains of southwest and south-central Montana right now is like a book resting atop potato chips.
For more detailed information:
The snowmobiler killed in an avalanche on New Year’s Day, and his companions, were riding in an area of the Gallatin National Forest that is closed to winter motorized use.
“The area they were in, Onion Basin up Portal Creek, is closed to snowmobiles,” said Mariah Lueschen, a spokesperson for the forest.
Onion Basin is in the 155,000-acre Hyalite Porcupine Buffalo Horn Wilderness Study Area.

WINTER SPORTS — “We had it going on for a while, the melt-freeze I mean,” said Kevin Davis in today Idaho Panhandle Avalanche Center weekly forecast.
“Last weekend the conditions were great and if you could have had this week off you would have been getting into some corn snow conditions. No solid overnight freeze put an end to that and you'll find slushy snow prevailing.
“Possibly a little dust on crust up north and to the south will be slush on slush.
“Be careful on steep terrain if you venture out today and this weekend. Use you spring travel techniques. I'll post that next week. This is our last official advisory this winter.”
WINTER SPORTS — “A lot of snow in the past week, and it fell with a lot of wind,” warns Kevin Davis in today's weekly advisory from the Idaho Panhandle Avalanche Center.
Winds were mainly out of the west so use caution on the easterly aspects, NE through SE. I found a decent slab over a weak layer of facets on a north aspect in the Selkirks yesterday and I wouldn't have been on any steep and exposed slopes with that under me.
No shooting cracks or whumphing but if you dig down through the powdery snow you'll hit an ice crust, isolate a column on that and give er a whack and see what happens. Go or no go? It'll settle a little bit today but check it again this weekend. Great conditions out there right now.
WINTER SPORTS — Warm temperatures have softened snow to the tops of the region's mountains this week, according to avalanche forecasters who were out in the Selkirk Mountains Thursday.
“It may have tightened up a bit at the higher elevations but it was wet yesterday, to the top,” says Kevin Davis in the intro to today's report on avalanche conditions from the Idaho Panhandle Avalanche Center.
“Temperatures seem to be coming down a bit, from 40 last night, but they may go up before they drop back down. When its this warm you want to be a little more cautious of steep terrain.
“Some surface slushies were running yesterday. More snow on the way by Saturday night, with strong west winds.”
WINTER SPORTS — Be careful out there winter snow goers. The warm front with heavy wet snow is creating high avalanche danger in the region's mountains, as you'll see in this National Weather Service warning for the North Cascades issued Wednesday evening.
The Idaho Panhandle Avalanche Center posts its weekly advisories on Fridays.
WINTER SPORTS — Backcountry snowgoers have been finding great conditions here and there, an reasonably safe slopes.
“Look for sheltered areas to have the lightest surface snow,” says Kevin Davis in today's avalanche conditions report from the Idaho Panhandle Avalanche Center.
“Exposed slopes were firm from wind and sun. Some shears in the upper 1-2 feet of pack but nothing pulling out with energy that concerned us. You will want to be concerned when the new snow comes in, possibly wet, heavy, and windloaded. Bad combo. Know your lee aspects.”
WINTER SPORTS — Snow conditions are “mostly stable” in the region's mountains going into the weekend and the weather forecast calls for improving stability from the slight weak layers discussed in this week's avalanche advisory by the Idaho Panhandle Avalance Center.
WINTER SPORTS - Weather is causing changes in snow stability that backcountry skiiers, snowshoers and snowmobilers should be aware of when traveling in the mountains today and this weekend, according to the Idaho Panhandle Avalanche Center's weekly report on mountain snow conditions.
“On easterly aspects we have a layer of buried surface hoar that is unstable and mostly isolated to sheltered slopes but it can be found from NE, E, to SE slopes with varying degrees of weakness,” said Kevin Davise, avalanche forecaster. “Due east seems to be where it is weakest. Other slopes are mostly stable but as temps go up today watch for weak layers developing on any steep slope.”
