FRISCO — All the world’s eyes focusing on the current round of climate talks in Lima, Peru, made me realize once again how much is at stake for those of us who love winter and snow. Of course, global warming isn’t going to wipe out all the snow at once, but that’s one of the things that makes the global warming issue so vexing. Even if we can’t see much change from season to season, there’s a good chance that snowfall patterns will be very different 50 years from now. Based on everything we know, it’s hard to say with any certainty that skiing will be be sustainable as a sport by the end of the century. Since I want my son, and his children, to have the same chance to experience winter the way we do know, I know that it’s imperative to #actonclimate. Continue reading

FRISCO — Tis the season … Even though it’s not Halloween yet, it is time to start thinking about putting together the annual Summit Voice calendar, which you can always custom order at our Redbubble gallery. Like every year, we’re asking for a little reader feedback to help choose each month’s image. And, as always, I had a hard time narrowing the choice to these five photos, all snapped in Summit County, Colorado. The sunset scenes were all taken on a single day, probably one of the most phenomenal sunsets I’ve seen in Colorado, with the sky going from orange and yellow to bruised purple, back to more orange. Comment in the box at the end of this post and tell us which one is your favorite shot! Continue reading

Colorado’s north-central mountains favored by this winter’s storm track

FRISCO — Summit County remained a target for above average precipitation in February, with both official weather stations reporting surplus snowfall for the month. The Upper Blue in particular benefited from the storm track, with the snowpack now approaching record levels.
To date, the snowpack in the Blue River Basin is the third highest on record, according to National Weather Service meteorologist Chad Gimmestad, who said there is a moderate potential for spring flooding in the basin. Continue reading

Higher albedo of snow-covered ground a factor in climate mitigation calculations

FRISCO — Snow farming is nothing new for ski area operators, who have long been cultivating the white stuff to help keep their slopes covered. Now, a recent study by researchers at Darthmouth College suggests that snow farming could also make sense on a larger scale, in the context of climate-change mitigation.
In a novel look at forests and snow, their report says that replacing forests with snow-covered meadows may provide greater climatic and economic benefits than if slow-growing trees are left standing in snowy high latitudes. In those areas, persistent snow cover reflects heat back into space, partially offsetting the effect of heat-trapping greenhouse gases. Continue reading

High avalanche danger prevailed across the Colorado mountains when two backcountry skiers died in snow slides Feb. 10.
High slide danger persists across the mountains
By Bob Berwyn
FRISCO — Colorado’s exceptionally deep snowpack turned deadly this week, as a backcountry traveler near Kebler Pass was killed in a large avalanche. Search and rescue crews also found another victim in the backcountry between Keystone and Breckenridge after a two-day search.
According to the Colorado Avalanche Information Center, the Feb. 10 Kebler Pass slide involved two snowmobilers caught in a “very large avalanche” on a south- to southeast-facing slope below treeline. The slide broke between two to five-feet deep, about 600 feet wide and ran about 750 vertical feet. Debris at the bottom of the slide piled up to 20 feet deep.

Shooting into the sun with an iPhone, using the camera’s HDR to capture a bit of the iridescence in the upper level clouds as a winter storm descended on Summit County.
FRISCO —It certainly feels like the heart of winter right now in Summit County, as well it should. Mid-January is the time for snow and ice, and this year Mother Nature has delivered on time. Today’s Sunday set is a little photographic homage to the white stuff, an important part of life in the Colorado high country in so many ways. Visit our online gallery at Fine Art America for a full selection of Colorado landscape images, available as fine art prints or greeting cards. Continue reading

2013 brought record levels of dust to Colorado’s mountains
More frequent desert dust storms dropping pollution on the Rocky Mountain snowpack is one of the climate change impacts affecting the Colorado high country.
By Bob Berwyn
FRISCO — Dust storms that darken the Rocky Mountain snowpack and speed snowmelt are becoming more extreme, according to new research. Particularly heavy dust-on-snow events can speed the melt-out of the snowpack by a full six weeks, all other factors being equal, said Jeffrey Deems, a researcher with the Western Water Assessment and the National Snow and Ice Data Center.
“In 2006 we were impressed at how much dust there was. Then 2009 turned up, and 2010, and 2013 was the dustiest year we’ve recorded in the San Juans,” Deems said, explaining that the latest study, put together by researchers with NOAA’s Cooperative Institute for Research in Environmental Sciences was aimed at updating previous work with data from those heavy dust years.
Last spring, on April 8, a single 16-hour dust storm dropped more dust on the San Juans than the annual totals in any previous winter since scientists started taking detailed measurements, said Chris Landry, director of the Center for Snow and Avalanche Studies in Silverton, which tracks the dust-on-snow events via a network of observation sites.
