Bikin' Again...

The last few years were hard on the Guzzis, first the 650 swallowed all the gas, then the 850 had electrical issues. So after putting off any meaningful work, except for ordering parts, finally got'em back together.

After replacing the ignition switch last fall, the generator light stayed on, so figured it was the voltage regulator. By the time the order arrived, the weather had turned to crap, so it sat all winter. But a rare burst of energy last week had it installed and back on the road. Still runs like a top.

The 650 gas taps had leaked fuel down into the engine and filled the sump. Replaced the taps last year, but then decided to rebuild the carbs. Finished them this spring, then replaced the air cleaners, fuel lines, and filters. Should hav'er on the road soon. Will then have two running bikes again, hard to believe!

Shear Blading and Thermokarst...

Here's your science lesson for today... 

About fifteen years ago, in the early to mid-aughts, there were a lot of forest firses around here. The local government, in it's infinite wisdom, decided to clear large areas of black spruce for fire breaks. This was done by shear blading. Shear-blading involves the use of a track dozer with a blade that shears the trees off at ground level during the winter months when the ground is frozen. The blade is supposed to float along the ground surface leaving the vegetative mat largely undisturbed. 

When clearing a series of fire breaks in the Smallwood Creek valley behind our place, the dozer operator apparently got lost and followed our dog trail, widening and clearing the trail as he went.

The trail after shear blading. The large mounds on the left are the vegetative mat that was stripped off, rolled up, and pushed off to one side. The Ski Doo is parked on the other side on the original trail.

 The state's contractor attempting to remediate the damaged trail with a "mini-excavator." Had they paid more attention to what they were doing and done the shear blading properly, none of this would have been necessary.

One of the gullies that formed out in the valley after shear blading. It's maybe 20-30 feet wide, up to 10 feet deep,  and extends for the length of the cleared area. It can be a challenge to cross with a dog team or even a snow machine.

One of the usual results of surface disturbance to permafrost soils is thermokarst. Karst is a term that's usually applied to limestone sinkholes, but up here it's used to describe the consequences of permafrost degradation. This is evidenced by dips, hollows or gullies produced by the melting of ground ice and subsequent subsidence of the ground surface. A year or so after the clearing,  forgot when, a pond began to form next to the trail right where the Ski Doo was parked in the first photo. Since numerous ponds and gullies were forming out in the valley where the clearing was also done, we were concerned that the erosion would get worse, maybe even making the trail un-runnable. While the state's contractor had attempted to reclaim the damage, we've been keeping an eye on it, even covering the pond with moss and leaves in the spring to keep it frozen longer into the summer.

So we hiked out there yesterday to check it out, we hadn't seen the pond unfrozen or without snow cover in quite a while. Surprisingly, it's apparently revegetated and stabilized, now it's just a little "tundra pond."  Hopefully it'll stay that way!

Spring? Not Just Yet...

After almost two weeks of sunny warm weather, we woke up to this the other day...

I'd meant to head out on the trail, maybe get down into the valley and check out the creek crossing, but wound up working on some projects around the house instead. By the time we went up on the trail today, this is what it looked like...

Lots of bare ground, not much of the recent snow left and the snowpack almost gone.  But at least I finished up on the sled pack that was started last month. Meant to get'er done for the dog sled trip to the park, but then that was cancelled (Blue Skies 3/21/21), so it sat for awhile. I've wanted to put pockets on the outside so it'd be easier to access the gear. Now I can put spare gloves in one, snow goggles in another, and maybe dog booties in the third. That way the main pack can hold all the ropes and extra gear and I won't have to fumble around, trying to find what I'm looking for, while the dogs are banging to go.

Happiness is a sled pack with lots 'o pockets!
