Larches and pikas and bears, oh my

The larches are turning, and I really wanted to get up to my favourite place to go see them. I have been to, and written about, Sparrowhawk Tarns before -- here, here and here. But I rarely hit the larches in their peak colour.

Larches are to Alberta what maples and oaks are to Eastern Canada. They are one of the few things that change our green forests to a beautiful colour in the fall. I wish they would last longer; they go from pale green to yellow to gold to gone in a matter of 10 days. Sparrowhawk has a magnificent grove of larches.

We started by picking up our friend Monty at the Canmore Nordic Centre, where the aspens and poplars are magnificent.

As you can tell by looking across from the Sparrowhawk trailhead, fall colour is not the "norm" here.
Still green
About 45 min up, we looked and found the day's first pikas.

They don't sit still long.
Running away
The fall colours of the bushes on the way up are brilliant.

When the larches start, everything just goes magnificent.

We passed even more pikas in this section...

In the larch
We emerged from the larch forest and got into the upper basin proper just in time for lunch. We stopped at the top of a knoll, sat down, and started to eat lunch. A few ravens were flying around, making a lot of noise. I followed them and saw something in the distance.
Our lunch view. But there's something there
We pulled out binoculars and saw something large and brown and moving...
Hey, that's a...
...which looked from our distance (of ~500 m) to be a grizzly bear. He was digging and rooting around a lump in the ground, and the two ravens were trying to get him away from whatever he was digging for.
Digging with company 
The ravens won't go away
After a few minutes, the bear lay down on the lump, but the ravens would not leave.
"Go away"
I shot a short movie of him.
Knowing fully well I would lose picture quality, I turned on digital zoom, and continued shooting.
Fuzzy, but
When we got home and looked at these photos, it became clear that this is not a grizzly, but a cinnamon coloured black bear. Ah, well. Seeing him was just awesome.

We left the bear to be (after each taking about 100 photos), and continued into the basin, making a heck of a racket. We passed awesome streams...

...and just beauty everywhere.
Looking back into the basin
On our way back, we just had to see if Mr. Bear was still there where we first saw him. He was. Lounging.
That's chilled.
The light wasn't nearly as good on the way down, but the larches were still nice.
Lovely colour
We saw more than just bears and pikas today, but not much. We did see the odd chipmunk.
Cute. And eating
What a fantastic day in the mountains. The larches were perfect, seeing the bear was amazing, and of course there were pikas.

And I hiked 17 km, climbing 780 m. Which is why I am now dead tired. Not bad for a guy recovering from a broken leg.

More de-mousing

After Jello and us caught 12 mice in under 3 weeks, we decided we needed professional help. Again. For the 3rd time. I wrote here how we pulled up the deck and thought we found the problem: a hole around the casing of a window we didn't even know was there.

The exterminator came, and looked, and found a few things we didn't see. The mice actually come in under a section of deck we did not remove (and who's removal would be VERY tough).
Look carefully
Two things are visible in the photo above.

  1. Where the concrete foundation wall of the house meets the siding of the garage, dead centre of the photo above, the garage siding has been chewed to make it bigger.
  2. About 5" to the right of this, hiding but visible is a grey conduit pipe. This is the wire that leads to the garage.
There's also evidence that the mice are using this as their main entrance. There are trails leading around and over that rock in the middle.

We also found a few other things:
  • There is a 3" standoff between the house siding and the house walls. Heaven only knows if there are ways mice can get up between the two.
  • That window we found is packed around its edges with fabric, mostly dark blue corduroy, ripped from an old pair of pants.
Bits of fabric jammed into the top of the window
The exterminator did a bunch of stuff:
  • He squirted expanding foam into the cracks around the window, including the big hole we found;
  • He put down a bunch of ZP. This nasty stuff, zinc phosphide, is a powder that gets on the mice. When the mice lick the powder off to groom, it turns into phosphine gas and they die within 2 hrs;
  • He put down some pesticide laced winter wheat pellets. 
But because he couldn't access the obvious entry point and seal it, nor access the entire wall to close off the 3" gap, we got no guarantees the mice would stop.

So Jello caught one that night. And so did we, in a glue trap. He caught another the next night...
Hunter pride
...and another the next afternoon. Then we caught another in a glue trap last night. Five mice in 3 days. So obviously, the exterminator's work wasn't successful.

I decided to try to attack the problem from the inside. We went into the basement, took down the suspended ceiling along the problem wall...
Tiles removed
...and cut portholes in the drywall above the ceiling level to access the foundation wall.
A bunch of holes
Along the way we found a dried up, desiccated mouse.
Say cheese
The way the basement was finished, it was difficult to get 100% visibility of the wall, especially in the problem corner. But we did find where the wires come in, a hole big enough for the mice, and a lot of poop.
There's room there
We also found that the expanding foam the exterminator dude squirted in around the window did indeed make it into the house. We found another couple of spots where there were holes, too. So I took some of my own expanding foam and filled everything I could see.
Awkward reaching into tight spots
Did we get everything? I doubt it. Did we get where the mice are coming in? Maybe. Only time will tell. What makes me nervous is that the conduit visible in the top photo above is 5" to the left of where the mice chewed the boards. You can see that 5" to the right of where the wires exits the house is nothing: no means of entrance. So I have to assume that the mice make it between the siding and the walls, then come in via the electrical conduit hole in order for what I just did to work.

Here's hoping.

More physiotherapy hiking

Last week was winter.
A plant in 28 cm of snow
This week is summer. All that snow is essentially gone except up very high, so we took advantage of the spectacular weather to continue my "hiking for physiotherapy". I picked C Level Cirque, a hike that is similar in distance to the wander I did pre-winter up at Sunshine, but has a bit more height gain (580 m vs the 325 m I did at Sunshine). It's not my favourite hike; there's a long, boring forest walk in the middle, and the trail's rooty & rutted. But it's not far from my house, and there's always pikas -- and I had not seen a pika yet this year.

The first stop is always the Lake Minnewanka overlook, only 45 min up the trail. It's at the old coal mine workings.
A spectacular view on a spectacular day
I even got a panorama from that viewpoint.
My house is in that photo (sort of)
It takes another hour of trudging uphill through a not-terribly-interesting forest to get to the next views.
Looking down the Bow Valley to Canmore and my house
Then 10 minutes after that, you get to the cirque -- which is a mighty impressive big bowl of rocks -- and the end of the official trail.
A very big rubble field
If you blow up that picture and look really closely, you'll see a trail leading up the right side of the basin. Follow this and you will get yelled at by pikas in the boulder field...
My first pika of the year
...but at the top is a small grassy meadow of rocks which is pika heaven and an idea place for a sit and a snack.
Monty & Karen making the crest
In addition to the pikas, there are overly friendly Golden Mantled Ground Squirrels, who have obviously been hand fed once or twice (say, by the Dutch tourists we ran into who were feeding them apples).
Chubby
But mostly there were pikas, at least 5, all industriously collecting grass...
Hard at work 
Quite the mouthful 
The endless searching for green stuff 
Watching me watching him
...filling their middens...
The stash is under that rock 
A winter's supply, or part thereof
Initially, the little dudes don't want to have anything to do with you, and don't like you being around -- so they just hide. But once they figure out you're not going to bother them, they go back to work storing grass for the winter, and stop paying attention to you, allowing some fairly close encounters. One little guy seemed interested in watching me watch him.
He's actually sitting still
Interested & observant... 
...but cautious and ready to run 
The money shot pose
It was a really glorious 26° this afternoon, very summer-like and not at all feeling like fall. Aside from colours turning on aspen, poplar and some avens, there wasn't much in the way of fall colour -- as yet.

But it's coming.

Surprises about how mice come and go

In the last 3 weeks, as a family, we've killed 12 mice in the house. Jello has most certainly done his share.
The hunter, the prey in his mouth 
Playing 
"You can run, but you can't hide" 
"Move and you're dead"
We think the mice started to come in when a few days of rains caused them to hide from the weather. Then it snowed, and they came in again. Now its getting cold, they're coming in for the winter. I'm sure that if we searched, we would find their food cache. A few months ago, we found about a pound of bird seed buried in Karen's sewing stuff. Last fall we found their store of mouse poison in my ski boot. We've been fighting the mice since we moved in (amazing, both the the 2012 and 2013 posts were both called "Smart Mice").

About the time we found the 4th mouse this go-round, we decided to call the exterminator back. There's no exterminator in the Canmore area any more; we have to call one in from Calgary. The one we use in Calgary guarantees no more mice if they can access the entire foundation wall. Two walls of ours are under a deck, which we didn't want to pull up. But with this mousal onslaught, we said (un)screw it, and today pulled up some boards in prep for the exterminator's visit on Wednesday.

We started by pulling a few boards up beside the wall we thought was their access point.
Two removed
It was MUCH harder to get the boards up than I imagined. The brilliant deck builder had overdriven most of the brass screws, and the deck had been painted a number of times since the deck was built. So, more than half of the screws were embedded 1/4" - 1/2" into the boards, and I had to carve the wood away to get them out. Most were stuck, so in order to not strip the screw heads, I had to hand-loosen them. It was slow and painful work (and I have at least 3 blisters to prove it).
Carved out and exposed
We got those first two boards out as we were instructed by the exterminators some months ago. We looked underneath the deck and saw something strange.
See that line in the darkness?
We discovered that the deck was built over an old, boarded up, basement window. This was news to us. We had a no idea that there was a window under there. We realized very quickly that we had to pull up a couple of more boards in order to access that window.

Another two painful hours of pulling screws and...
The boards are up
...we found the window -- and the way the mice get in. Whoever covered the window boarded the window up, but the window casing doesn't actually meet the hole cut in the foundation wall.

The metal window well, and the window
That lower right corner is the issue
It should surprise me that there's a window in the house we didn't know was there -- but it doesn't. It should surprise me that the way the window was sealed up when it fell into disuse wasn't even marginally done correctly -- but it doesn't. It should surprise me that my house is full of mice -- but it doesn't.

The exterminators are here in two days. Jello's gonna have 48 more hours of fun.
