Hot or Cold

Spring Time

March, at the South Pole it is the beginning of night. Here in Utah it is Spring time, and Spring in Utah means that it is too cold one day and too hot the next. This makes me ask:

Which do you like better, hot or cold? Feel free to post answers in the comments below.

Cold

When I was a kid winter was my favorite time of year. I think this is mostly because my birthday and Christmas are in December and like most kids those were two of my favorite days. I always loved it when it would snow on my birthday, which it did frequently. As a teenager I would go skiing, snowmobiling, and just have a blast playing in the snow. 

Hot

However, as I've gotten older I prefer warm or even hot weather. It is common in Utah for people to complain about it being too hot during the summer, and complain about it being too cold in the winter. I don't complain about the hot weather, I love it, but I am no longer a fan of the cold weather. I have biked through the desert in 120F and loved it. I love biking in the mountains in the summer, wild flowers, the smell of the pine trees, and just being outside. 

Cold

But the cold winter means people quit biking which is hard for my bike store. Plus since I have put all my money in the store I don't have much for necessities like heating my house. Through the winter we keep our house just barely warm enough to keep the pipes from freezing. Well, we try to keep it warm enough to keep the pipes from freezing but sometimes they freeze anyway. 

To the Moon

So why would I want to spend a couple months in the extreme cold of the Antarctic? I think JFK summed it it well when he said, "We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too."

I Can't Wait

I haven't looked forward to the next winter with such anticipation, such desire, hardly being able to wait, since I was a kid.

Videos

I had a meeting with some of the people that will be working on the documentary for  The South Pole Epic. I have a few videos I have created on some of the rides, some of them I have uploaded to YouTube. It will be nice to work with people that can produce professional quality videos. I like my videos for what they are, but I am a mountain biker not a movie maker.

We got a few inches of new snow this morning, so I went for a "training" ride. Training ride, because it was on the snow bike, in the snow, and kind of cold. However, it was only a couple hours long and it wasn't extremely cold. I didn't get any video from today's ride, but here is a video from the same area I was riding this morning.

Goodnight?

Tomorrow is the Spring Equinox, so that means that it is the end of day and beginning of night at the South Pole right?

Sun appearing above the horizon 30 hours before equinox

Well, not really. It is complicated but here are the basics:

One Sunrise - One Sunset

There is only one day and one night per year at the South Pole. The sun sets in March and the rises again in September. After sunset in March the sun stays below the horizon, and after sunrise in September it stays above the horizon traveling around the horizon instead of across the sky.

At the Equinox

If the world was perfectly round (it isn't) and the South Pole was at sea level (again it isn't) and the horizon was completely flat (and once more it isn't) then at the Spring Equinox the sun would be half way above the horizon and half below the horizon. But sunset is when the sun is completely below the horizon. Here in Utah the sun goes from half visible to gone in a matter of minutes, however at the South Pole it takes another 16 hours for the last half of the sun to move bellow the horizon. 

Seeing Something that Isn't There

Now it gets crazy. The earth's atmosphere bends the rays of light coming from the sun. This makes it look like the sun is still up after it has set. At the South Pole this effect lasts for about 36 hours. So the sun will appear above the horizon for a day and a half after it has already set.

And it Doesn't Stop There 

The taller you are the more distant the horizon is. So, the taller you are the longer until sunset. Since the Sun is traveling around the horizon instead of across the sky and with all of the factors above it is next to impossible to figure out where the sunset will occur. This would be no big deal if the ice around the pole was flat, but it isn't. So where the sun is when it sets can change when it sets by as much as 10 hours.

So I was going to say good night as the South Pole "day" is about to end, but I guess there are still a couple more days of day left.

Here is a good article that explains about sunset time at the South Pole.

Oh well, good night anyway!

Going South to Get to North Pole

When I was a young kid we lived so far north we had to go south to get to North Pole. I've told that joke my whole life. You see, we lived in Fairbanks Alaska which is a little north of a town named North Pole.

I don't remember much of  Alaska, we moved to Utah when I was only three. But I do remember my red parka. It was down filled and the hood was lined with fur to keep the face warm in the -40F or colder. I have to admit, one of the things I'm excited about for this expedition is being able to have a good reason to have a good polar parka. I know, silly, but I guess I like a little nastalgia. I've thought a lot about my Alaska heritage lately. I'll have to share more of my Alaska stories in future posts.

Ice Cap/Polar Plateau

Height of Antarctica

Antarctica is the highest continent on Earth: average elevation is 8,200ft (2500m). The elevation at the South Pole is 9,300ft (2835m). The highest point on the icecap is in Australian Antarctic Territory at 13,451ft (4100m), at 82° 20'S, 56° 30'E. Mount Vinson is the highest mountain in Antarctica at 16,050ft (4892m).

The South Pole is located on the Antarctic Polar Plateau. The average elevation of the Polar Plateau is 9,800ft, and the ice is about 9,000 feet thick at the South Pole. The South Pole Epic will start at the edge of the Antarctic continent and travel to the South Pole. That means we will start near sea level and be at 9,300 feet at the pole. So in general we will be biking uphill with a headwind (see post on katabatic winds). 

View of the Polar Plateau

About 98% of Antarctica is covered by the Antarctic ice sheet, a sheet of ice averaging at least 1.0 mile (1.6 km) thick. The continent has about 90% of the world's ice (and thereby about 70% of the world's fresh water). If all of this ice were to melt, sea levels would rise about 200 ft (60m).  The weight of the thick ice sheet has pushed the land down so far that if it were removed, the land would rebound nearly 2,000 feet.

The Journey

Working on the route for a mountain biking trail this morning, we decided it should drop down and along a ridge before hitting the top of the hill. After all, it is more about the journey than the destination.

The South Pole Epic is that way also. Sure, getting to the South Pole is a critical part of the expedition, but how we get there is the real story. We will face crevasses, sastrugi, extreme cold, and whiteout snow storms, and who knows what other challenges we will have to conquered to reach the pole. But that is why it is called an adventure, and is what will make it worth doing.

Bonneville Shoreline

People ask what I'm doing to train for the South Pole Epic. Well, I usually go for a bike ride as soon as it is light enough to see. This morning I took a few customers up Corner Canyon in Draper. This is a bit of a difficult time of year for mountain biking. Most of the trails are muddy and it hasn't gotten cold enough at night to freeze them solid. I don't like damaging trails so I don't ride muddy trails.

I have to finish rides in time to open the bike store so with the daylight saving time change I don't have a lot of time to ride in the morning. As the trails get dryer, and the sun comes up earlier I'll be able to go for longer rides.

Today's ride wasn't strenuous enough to call it a training ride, but it was fun.
