The winter severity index for the International Falls area was 48 on Wednesday, reports Larry Petersen, Minnesota Department of Natural Resources area wildlife manager.
The WSI was 104 last year at this date, and 64 two years ago.
The average WSI for this date is about 65, said Petersen. The harshest winter in the mid 1990s had an index of 123 on this date.
All the winter severity data dates from 1966 to present.
The snow depth is around 12-16 inches in the International Falls vicinity, reports Petersen.
“We have now reached the point, at least in northeastern Koochiching County, that snow depth will contribute to the index,” he said.
The winter severity index is a standardized number natural resource managers use when considering impacts of the winter on deer. It is calculated using temperature and snow depth in the period from Nov.r 1 through April 30 or whenever winter ends. Every day the daily low temperature is 0 or below is one point, and every day the snow depth is 15 inches or deeper in an open aspen woods is one point. The points are added each week until winter ends.
International Voyageurs Snowmobile Club
Well we finally got some much needed snow today (Tuesday). We received around 3-4" with another couple coming tonight. With all our trail system freshly groomed it should be awesome riding.
Our operators have a large supply of fire wood at our shelters for all to use. Please keep the fires within the fire rings and make sure the fire has died down before leaving. The new bridge on the Arrowhead Trail west of Highway 53 has been completed and the old bridge has been removed with new signage installed by the Department of Natural Resources.
It's MnUSA Winter Rendezvous weekend with a lot of groups out riding from many different areas so please pay special attention on the trails. So get out this weekend and ride the best groomed trails around, and be safe.
Voyages National Park
Voyageurs would like to welcome the Minnesota United Snowmobilers Association (MNUSA), members of which will be riding the park and area trails this weekend.
Fresh snowfall this week has helped improve all trails and portages just in time for their 2015 Winter Rendezvous. Snowmobilers can enjoy the ease of traveling on groomed surfaces at Voyageurs National Park thanks in part to the park’s gateway community snowmobile clubs: International Voyageur, Ash River – Kabetogama Snowdrifters, and Voyageur Trail Society.
Visitors to the park can enjoy the groomed trails by visiting a scenic rock formation, Grassy Bay Cliffs. Located on Sand Point Lake between the communities of Ash River and Crane Lake, Grassy Bay received its name from being a portage that was most likely used during the fur trade. The portage was a short cut between Sand Point Lake and Namakan Lake, and its earliest map reference was in 1913 on the International Joint Commission map.
Outstanding geologic outcrops, such as Grassy Bay Cliffs, are one of the reasons Voyageurs National Park was established. Visitors to this area of the park can see a unique outcrop of the Lac La Croix biotite granite, the same rocks that make up much of the Boundary Waters Canoe Area Wilderness. While the geologic story of the park dates back 2.8 billion years and shows a variety of different geologic features, this outcrop shows some of the “younger” rocks of the park, “only” 2.6 billion years old. In addition to its impressive age, this rock outcrop reaches more than 80 feet high and is truly a scenic experience.
The snowmobile speed limit within the park is 45 mph on frozen lake surfaces and 25 mph on all overland portages. Speed limit signs are posted at trailheads and portages. The speed limit for the ice road is 30 mph.
