This morning's baby marmots
The kids are growing up in a hurry, I had to stop and let Jasper watch for a while before Julie and I go to California.

The heating pad in our garage fridge
Just thought I would share this odd little battle with physics.
We have a standard fridge out in our garage. Its freezer compartment is in the bottom, although after a while I realized that made no difference. The problem is that the refrigerator compartment was doing just fine, but the ice cream in the freezer kept melting. I assumed it was the door not closing completely, which had occurred once or twice, so I order a remote thermometer with two sensors that would alarm at certain temperature settings.
Watching it for a few days, I noticed that the refrigerator compartment was holding around 36 degrees, which is just fine. The freezer was varying from 3 to 20, which way too warm. That in itself was a lesson for me. I thought anything below 32 was freezing, so 20 would be dandy. A freezer should really sit between -10 and 0. Not everything freezes at 32.
I set the temperature for the freezer to "Coldest" but that had no effect. So I did what we all do and went to Google. It didn't take too long to learn that I was not unique in the world and that a GE service call would do me no good. First, the speced operating temperature for the fridge starts at 60 F. That was a clue that they weren't supposed to work at cold temperatures. Then I learned that there is no thermostat in the freezer, only the refrigerator. When you change the freezer "temperature" setting, all you are doing is controlling a damper that forces more or less of the cold air into the freezer.
So, the problem with a fridge in a cold space is that the refrigerator stays cold. Our garage is about 40, so that compartment is almost always happy. You could just leave the door open. That means the compressor never gets turned on. The freezer then slowly heats to the same temperature as the garage. Mystery solved! Now, what in the world do you do about it.
Once answer is to buy a special garage fridge, which is controlled differently and costs about 3 times as much as a really nice fridge. I went with plan B (cheap). I bought this little $25 heating pad designed to keep your animals warm. It is a 25 watt pad, giving about as much heat as a pair of night lights. I plugged it in and stuck it in the fridge. Now, every once in a while, it warms up enough in the refrigerator compartment to force the compressor on. A little fine tuning and I have the freezer running right where I need it. For a while, it was actually getting way too cold. Come spring or summer, I will pull the heating pad out and let Mother Nature keep the garage warm enough.
Seems silly to stick a warming device into a fridge but this was by far the best of the alternatives. If the compressor was running too much, I would have returned the heating pad and gotten one that was closer to 15 watts.
I wondered why I hadn't had this problem before. Next door we had a full freezer, and it was in the house. Back in NC, we didn't have too many days with lows below zero. I guess if I lived elsewhere, I might have to worry about the compressor overheating.

U.S. Snowboarding & Freeskiing Grand Prix
It was a big weekend of competitive ski and snowboard events here in Park City.On Friday I went over to see the skiers hit the PCMR halfpipe and on Saturday I returned to watch the snowboarders. These young athletes are incredible to watch. In addition to their obvious skiing and gymnastic skills, they are obviously both brave and a bit of crazy.
I have always noticed that the snowboarders come further out of the pipe than the skiers. Just the same, let's do some quick math. The top of the pipe is 22' off the bottom. Those are 6' guys standing on the rim. The skier looks to be another 15 feet above them. That means he is about 40 feet above the base of the pipe.
A flyby. It looks so static, but they are in the middle of some number of twists and flips. Looks like they just stopped by for a visit.
Another view of how high they get. At least this guy is looking down.
But sometimes bad things happen, like landing on the rim instead of dropping down the steep wall. That means you stop suddenly and with a lot of force. Fortunately he was ok.
Patriotic.
The next day was the boarders. Kind of like the skiers not going as high as the boarders, the women don't go as high as the men.
Until 15 year old Chloe Kim comes along. She is the women's version of Shawn White. When she does her run, she seems to be doing a different sport than everyone else. Just amazing! And 15!
She had already won the event before she did her last run. Sometimes they will just do some little tricks to show off for the crowd on their "victory lap". Instead she did the first back-to-back 1080s ever done by a woman in competition, earning her the 2nd 100 score ever given.
For the boarding event, I was fortunate to get a Photo pass, which meant I was right on the lip of the pipe. It is a bit unsettling to be looking through a viewfinder as they come flying by. This is a wide lens, zoomed all the way out. Tough to make out the detail on anything but a full rez version of the photo, but I can see myself in her goggle reflection.
Just HUGE tricks and flying forever.
I love how the colorful boards pop against the sky.
One of the more stylish freeze frames. I don't know how to capture the energy and motion without video. I tried a few longer shutter speeds, but those looked like crap.
Quite the crowd for the event. People were packed in all down the pipe and then tons at the bottom.
Now for the odd shots I tend to end with. This guy looked like he was examining my camera as he flew by,
I normally would just toss this one. It is hard to make out the boarder with all the background noise. I liked it though, because with the flat perspective of the longer lens, he looks a bit like a giant about to squash all the little people.
And the cute prize goes to....
This little herd of munchkins. Not sure how they got to the top of the halfpipe. It is quite the steep hike. Lord knows they were having a blast getting down though! Some were sliding, others rolling. If any walked it was only for a few steps before they decided the alternatives were much better.

Ice castles over in Midway
Arnie, a friend from our camera club, called and asked if I wanted to join him on a photo trip over to the ice castles in Midway. I've seen them on the news and read about them in the paper. It is an annual winter event. I have never been to it and hadn't thought about it as a photo opportunity.
What they do is build giant ice structures. You walk through them and around them. That by itself would be a bit boring. The cool part is that they put colored lights inside the structures and do a poor man's light show.
This is what we saw as we first got there. The sun was setting and there was still a fair amount of light.
As it got darker, the lights began to have their effect.
I liked this one because there was just enough light in the evening sky to show the clouds on a long exposure.
All sorts of different shapes of ice.
I am not sure what the process was for making everything. It has to be some fairly slow drip to get all the icicles and not just a giant ice blob.
No color in this one, but it was looking straight up into the sky from the ground. I thought it was a cool perspective. The biggest challenge was trying to find the right focus when the camera was on a tripod with the back aimed straight at the ground and the focus points all centered on space.
There were little caverns and pathways. The challenge was trying to find a shot without a mass of people.
Some of the shapes left me wondering how they were created.
One our way out, we stopped to look at a little fountain they had. Clearly this volume of water was too much to create the interesting shapes but perhaps it could build a base for something.
But the lighting and long exposures made the fountain look pretty cool.
So, glad I went, but it is one of those things that you check off and don't go back for another few years, or decades. While you don't see it in the pictures, there were hordes of people there on a Thursday night, all paying $10 each. Seems like an interesting business to be in, as long as winter stays fairly cold.

Skiers jumping at Park City
I went over to shoot an event in the half pipe, but it was a bust. Right next to the pipe are some big jumps and it is always entertaining to watch the local youth throw their bodies into the air.
