Trail Conditions

In 2014 we purchased and began using a John Deere Gator with Camoplast tracks to handle the bulk of our ski trail grooming. It also pulls our trail mower through 22 miles of rough trails during the summer.

As a result of a couple major breakdowns involving the Camoplast tracks, we’ve learned to carefully monitor the tightness of the bolt/washer combination that secures the hub bearings and holds the entire track on the Gator axle. Every 50 hours we perform a safety check on the tightness of the 12 mm diameter hub bearing bolts that hold everything together. If we discover a bolt is starting to loosen up, we replace it. However, on two occasions the bolt itself snapped off - requiring a delicate welding operation to mount a nut on the bolt shaft so the bolt could be removed. This happened most recently just one week ago.

The Camoplast tracks that we use are realistically designed for recreational use. However, we demand a lot more of the tracks when pulling heavy grooming implements up hills, down hills, across hills, over bumps and ridges. Even though we’re using new bolts and washers when they need replacement, they still have difficulty withstanding the abuse.

After one of these bolts broke off a week ago, we called Camoplast in Canada and spoke with a very helpful engineering technician. He knew that ski trail groomers in Europe had greatly diminished their problems with bolt breakage through one specific modification of the setup: they substitute a much thicker washer. This makes a lot of sense. We’ve noticed all along that the original washers tend to deform (cup) within the first 100 hours of use - probably allowing the bolt to loosen, perhaps allowing too much play at a point where the mechanical forces are extreme.

So this past week, we tried finding a thicker heavy duty washer by calling Fastenal, and by scouring the internet, and by speaking with representatives from several big online companies that specialize in selling fasteners. Nobody could provide what we were looking for!

Then an AHA! moment. How about trying the machine shop located 3 miles from our trailhead?

CPH Enterprises Inc said “Of course! - WE CAN DO.” They took the original washer, recommended an improved fitment for the bolt, and later that day provided a bid for fabricating the washers we needed. We gave the go ahead, and actually had the opportunity to watch the machining in action.

They used a Waterjet Machine to cut the new thick heavy duty washers. After programming the specs, it cut the washers using water pressure of 50,000 PSI. I’ve never seen anything like it, truly amazing!

Think Global, shop Local.

Snowshoe Trails - Here's the scoop

• Back in 2012, John Kann developed the first of our 'Snowshoe Trails'. Soon he was joined by Dan Bjugstad - and they've been primarily responsible for maintaining and expanding the network of trails. From time to time, several of our members/volunteers have helped brush out the trails.
• The snowshoe trails weave up and down through various stands of timber.
• John and Dan quickly realized that good directional signage would be important. Sheets of yellow poly were purchased for the sign material.
• Pretty soon, clever directional signs began appearing. And as the trails expanded, this required a lot of signs.
• Recently, John shared more of the background regarding our highly visible snowshoe trail signs. Ryan Kann (his son) has been doing the screen-printing, and Ryan provided photos and videos as an example. Fascinating!
• Many thanks to Ryan and Ambient Inks (Eau Claire) for donating the time and materials.

Check out the videos and images below - an eye opening introduction to the art of screen-printing. Ryan makes it look pretty easy.

Enjoy stomping our snowshoe trails. The signs are placed at critical locations to keep you on track. If you'd like to be high tech and follow yourself on your smartphone, our georeferenced maps are free and available when you 'Get the Avenza map' from our website. This app communicates with satellites, and works in the absence of cell towers!

Screen-printing photos/videos are courtesy of Ryan Kann. Photos from our 'Ridges' snowshoe trail were taken February 2019.

This step shows the design being printed on to the screen which is coated in a light sensitive emulsion.

Next the screen/design is exposed with a bright light which hardens the emulsion around the design creating a stencil.

This step shows the unhardened emulsion being washed away with a power washer leaving you with a screen stencil to print with.

This step shows printing the signs using the screen previously made. In this case 15 signs were put on one screen to be efficient, and the signs are cut apart later with a bandsaw.

Most of December 2020 was dry and warm. Instead of skiing the Blue Hills Trail, we’ve been hiking its ski and snowshoe trails. A recent return to colder weather allowed nearby lakes to freeze solid, and during the middle of the month we enjoyed skiing a 1-inch coating of snow on always beautiful Audie Lake (located 2 miles northwest of our trailhead).

Then the weather forecast got us all excited, calling for snow a couple days prior to Christmas. We started closing off traffic on the ski trails, hoping to retain the little snow already on the ground. However, December 23rd was warm with too much rain; toward evening the winds began howling, temps plummeted, and wind whipped snow blew on by. The following day temps were in the single digits and when we inspected the trails, we were pleasantly surprised to find about 2.5”-3” of new snow stuck to the ski trails. Just enough to start some early season grooming.

After several days of grooming, today (December 27th) we're enjoying very good skating and good striding on 'Excelsior Road' (West Side) and the 'Gravel Road' (East Side of the trail system). The rest of the trails have a thin base with an irregular surface, grassy patches and dirt spots - skiable but not nearly as much fun as the two 'roads'. Take a look at the maps (images below) for a quick summary of the open trails.

Here's what groomers have accomplished since the rain/wind/snow event of December 23rd:

• Packed (rolled) 'Excelsior Road' (West Side) and the 'Gravel Road' (East Side) on December 24th
• Packed (rolled) many of the East and West trails December 25th
• Packed (rolled) more of the East Side trails the morning of December 26th
• Brought out our big G2 implements (finishing tools) and groomed 'Excelsior Road' (West Side) and the 'Gravel Road' (East Side) the afternoon of December 26th. This included setting a shallow classic track.

Here's an inside view of our grooming logic:

• At the beginning of the ski season, the initial grooming is targeted at knocking the air out of snow next to the ground so the interface can freeze into a protective layer and allow frost to penetrate. If it’s cold enough and dry enough we use rollers for this first step. During that first step, we often discover damp areas that need to be compressed so they freeze up.
• As soon as the base is thick enough, out come the finishing implements (we use Tidd Tech Generation 2 groomers) to start sculpting the surface. We start setting classic track only after the base has set up AND when the base is thick enough to minimize exposing grass, dirt and rocks.
• On our trail system, we have a couple of gravel road surfaces that tend to freeze up and hold snow earlier than the rest of the trails. That's where you'll find the best skiing right now (look at the maps below).
• So much of the good skiing in the days ahead is dependent on the summer/fall trail maintenance. This includes mowing, bulldozing to deal with erosion, repair of bridges & culverts, chainsaw work to clear downed trees, and brushing the trail margins. Please join us when we put out the word seeking volunteers (we have an annual work day late September). 

Our head groomer put in an 8-hour day yesterday, and was willing to return late evening to touch up some trails. We told him to rest up, enjoy family, and wait for some fresh snow. No grooming today.

The Blue Hills Trail is a favorite place for many hunters during the fall. Since it is non-motorized, it provides solitude that’s hard to find elsewhere. Bird and deer hunters are especially appreciative.

For many decades, a certain group of hunters from the Chippewa Falls area has camped in the parking lot by the warming house during the Thanksgiving gun deer hunt. Their tradition includes decorating their campsite with Christmas lights and inflatable characters. Quite a site!

The Blue Hills Trail has 20+ miles of trails that grow on you, and many trail users give back in their own way.

The group from Chippewa Falls has ‘given back’ by helping develop the signage for the Blue Hills Trail. At each of 60 intersections you’ll find a metal map holder that protects our laminated maps from the weather and curious critters. Each trail that branches from an intersection has a metal reflective sign providing directions. Thank you to our friends from Chippewa Falls for their part in keeping us oriented and safe on the Blue Hills Trail.

It was a busy summer and fall for volunteers maintaining the Blue Hills Trail in northwest Wisconsin. For the past few years, wet summers have aggravated areas prone to erosion. Fortunately, the latter part of this summer was quite dry. As a result, several important projects were completed.

‍

Here’s a quick summary of our accomplishments:

• Approximately 50 hours of trail mowing.
• Mowed and trimmed the trailhead (warming house etc) on three separate occasions.
• Repaired 1200 feet of badly eroded East Side trail by dozing and seeding.
• Filled erosion adjacent to an important East Side culvert by placing bundled straw and shoveling soil.
• Cleaned out three areas of creek debris requiring chainsaw work.
• Dealt with 3 plugged culverts that flooded and created impassable trail segments.
• Repaired the crumbling floor in our older shipping container.
• Cleaned and stained the warming house exterior.
• Replaced a failing culvert on the West Side
• Built a new bridge to cross a small intermittent stream on the West Side
• Brushed and cleared branches and windfalls from about 70% of the trail system, East & West.
• Brushed out a large portion of the snowshoe trail.
• Repaired the log corduroy of an East Side stream crossing.
• Chainsaw work on the West Side.
• Repaired (shoveled) ruts on a short section of the West Side trail.
• Replaced cable barriers at two vulnerable intersections along Rut Road (East Side).

‍

Details regarding some of the major accomplishments…

Bulldozing

Erosion control is always an ongoing battle in the Hills. The annual spring runoff and all-too-frequent summer deluges take their toll on the downhills. Our bridges appear to be in good shape. However, on the East Side the long downhill north and southeast of intersection #5 really took a beating this summer. The washouts in this area were repaired with bulldozing performed in early August, with grass seed spread quickly thereafter. Many thanks to DNR Forester Gary Sarauer for his dozer skills, and the Rusk County Forestry Department for donating the cost of Gary's dozing time.

Staining the warming house

Our lovely warming house at the trailhead was built in 1998. Since it's on County land, technically it belongs to Rusk County. However, it really 'belongs' to our membership since we're responsible for its upkeep. It's been stained on two prior occasions since it was built. This summer, we hired Dave Roth (Ladysmith professional painter) who performed an exterior beauty treatment. Thanks to Dave for his extra special attention in cleaning with an industrial cleaner, then pressure washing, then returning a couple days later to brush on a Benjamin Moore ArborCoat translucent waterborne stain. In the absence of power and running water, that was quite a challenge. Thanks to Bjorn Hanson (Burnell's Decor in Rice Lake) for donating the stain. Thanks to Jeld-Wen Windows (Hawkins) for donating and replacing all the windows in January 2020.

Unplugging a culvert that was flooding the trail

In July we discovered a plugged culvert on the trail that crosses from the East Side to the West Side trails (this culvert is located between #23 and Letter L). The plugged culvert caused water to back up parallel to the Fire Lane Road for about 1/2 mile. Water was briskly flowing over the ski trail, and threatening to wash out the trail and culvert. In August, Steve P and Jerry S teamed up to open the plugged culvert, and rescue this section of trail. flow, then photos showing the trail after the culvert was functioning normally. A huge thank you to Steve and Jerry!

Replacing an aging culvert

On the West Side, the steep down/up segment of trail between J-K has presented an always changing challenge for trail maintenance. Seems like each year the water passing through that narrow valley (and associated culvert) finds a new way to make for a difficult trail crossing. We've tried various methods to negotiate the water that often flows over the trail: a sheet of plywood supported by 2x4s; taking delivery of a dump-truck load of rock to create a rock ford; bulldozing to repair the erosion; or in many winters, simply waiting for cold weather to freeze solid the standing water.

This summer, that area between J-K was flooded with knee deep water. After draining that water, we recruited a heavy equipment operator to evaluate the site. At his advice, we replaced the failing culvert where the stream crosses the trail. His backhoe work widened and smoothed the trail, and created a spot where high water events can bypass the culvert. ‍

‍

Bridging a small intermittent stream‍

For many years, we've battled with erosion problems at a specific trench on the West Side of the trail system. It's located about 200 meters west of Letter I (refer to the above map). It's a 'choke point' for all the water that drains the west loop (D-F-G-H-I). As this trench has gradually enlarged and deepened over the years, it's posed an increasingly challenging obstacle for wintertime grooming and summertime mowing.

We've used various options to fill the deep trench, but they’ve all been washed out the next Spring. So now we decided to try placing a bridge at that site. In general, we try to avoid the use of bridges on the trail system since they're more difficult to maintain, especially with climate change triggering more numerous and heavier downpours.

The bridge was built in stages over the course of a couple weeks. The finished bridge looks pretty nice, it’s solid, and hopefully will withstand springtime runoff.

Enjoy the photos that follow.

Mountain biking at the Blue Hills Trail is most enjoyable on the West Side of the trail system. The East Side trails tend to be more damp and softer, and take quite a bit of dry weather before they dry out. The West Side trails are more firm, with only occasional wet spots.

In mid June, biking the entire West Side was a good workout. Grasses were only mid calf tall, and soils were firm. One short portion of trail between J-K was flooded knee deep, but could be crossed on foot.

Since so much of the trail system remains soft throughout the year, fat tire biking is a great alternative. The trails are wide, the curves are easily negotiable. It’s a great way to explore the trails during summer / fall.

Winter 2019-20 started early.

10+ inches of heavy snow November 27, 7+ inches of heavy snow November 30, 4+ inches of dense snow December 9, 2.5 inches of light snow December 12. Groomers had their hands full throughout December. This made for very good skiing over the Christmas and New Year Holidays. January added 14" of snow in generally light snow falls. February was dry, only 5" of snow. We had only one major rain event (1.5" of rain December 28), and the rain was absorbed into the abundant base. Trails were in great shape at Birkie time. Then warm weather moved in a week after the Birkie. The last grooming was March 13, but we were able to enjoy decent skiing into the beginning of April. All thanks to the big snows in late November.

We groomed a total of 57 times this past winter. Here’s the breakdown: once in November, 18 times in December, 19 times in January, 16 times in February, and 3 times in March.

Our head groomer and his crew were very willing to use our rollers - both of our rollers were used more this past winter than at any time in the past. As a result, this past winter the trails were groomed wider, and the edges were more firm. Groomers were very willing to try different techniques, and performed far more evening grooming than at any time in the past. This allowed the grooming to set up by the time skiers arrived in the morning. The classic track was in generally good shape most of the winter - the groomers were responsive to input from some of our most enthusiastic classic skiers. Thank you groomers!

The ABR compaction drag (we call it the 'Blue Thing') also was used more frequently this past winter. It was especially helpful removing high spots in the center of the trail, and when the trails needed a quick light touch-up of the skate lane.

Logging along Rut Road kept us from grooming that part of the East Side Core Loop the entire winter. Toward the end of that logging operation, it also disrupted our access to the West Side using the usual East-West crossover trail. However, one of the real pluses this past winter was the newly permitted use of Excelsior Road on the West Side for grooming and skiing. In the middle of December, after the gun deer hunts were done, a berm was plowed to block off traffic at the east end of Excelsior Road. We then groomed the entire 3 km length of Excelsior Road, and skiers were uniformly thrilled with the results.

Overall, it was a fairly long winter with very good skiing and snowshoeing in the Blue Hills. We hope the following photos trigger some good memories.
