How can we manage our time better? We are tired of staying up all night to finish our update!

dave_computer_sleepAmy and I were excited to read your comments, suggestions, and emails about the types of videos you would like us to make.  It is clear that students want more videos and information about the dogs. We will do our best to make some fun, and educational videos about the dogs over the next few weeks.

We have had a very busy week. Unfortunately, we have not been able to try all of your Fennel autograph ideas yet.  We have tried about half and plan to test the rest of your ideas this week. We will let you know the results of our tests soon. Thanks for all of your great ideas.

Amy and I have a bit of a scheduling problem.  During a typical week we are very busy guiding dogsledding trips from Wednesday morning until Sunday afternoon. During that time it is often hard for us to work on our videos and web updates. We usually start working at 7 AM and don’t finish until about 9 PM each day. We publish our weekly Notes from the Trail, Cast YOUR Vote, Dave’s Dilemma, Dog of the Week, and Animal of the Day on Monday.  For the past few weeks we have been staying up until 1 or 2 in the morning to finish all of our work before you get to school on Monday.

We are worried that our updates are not as good as they could be because we end up working late into the night to finish them.  Do you have any suggestions for ways we could change the updates or manage our time better?  We are hoping to find a way to make our updates better and not have to stay up until all hours of the night!

Keep Exploring!

Sharing the Wilderness with Wolves

Yesterday afternoon I noticed a group of ravens perched in a tree and the trail was covered in raven tracks and wolf tracks.  I thought there might be a wolf kill near by. Then I noticed a tuft of fur on the snow. Soon I realized the wolves had killed a white-tailed deer just about 10 feet from our dogsled trail.  There were large red spots in the snow and brown fur scattered around.  As my friends and I investigated the site we found lots of wolf tracks and the deer’s stomach.  The rest of the carcass was gone.

The wolves probably killed the deer only a few hours before we arrived. They may have heard us coming and dragged the deer carcass farther into the woods to finish their meal.  The dogs were very excited and were busy sniffing the snow.  After a few minutes of looking closely at the blood, fur, and tracks we continued down the trail.  It was amazing to see a wolf kill that was so fresh.

There are approximately 3,000 gray wolves living in Minnesota. The only state with more wolves is Alaska. However, wolves usually try to stay away from people. They have good eye sight, hearing, and an amazing sense of smell.  Usually wolves see, hear, or smell us from a long way off. They run away before we see them, but we see their tracks, scat, fur, and bones from animals they have eaten when we are out dogsledding.

Gray wolves are the species of wolf that live in Minnesota. To get more specific, the subspecies of wolf that lives in Minnesota is the Great Plains wolf.  In other words, Great Plains wolves are a subspecies of the Gray Wolf. However, there are different types of wolves living in different parts of the world. The two main species of wolves are gray wolves, and red wolves.  Wolves live in North America, Europe, Asia and Africa.

There are quite a few subspecies of wolves in the world.  The subspecies of gray wolf are the Mexican wolf, Great Plains wolf, Rocky Mountain or Mackenzie Valley wolf, eastern timber wolf, and arctic wolf.

Red wolves are smaller than gray wolves. They are usually brown with some black along their backs. The backs of their ears, head and legs are often a reddish color. Their legs are long, and they have tall, offset ears. Red wolves mainly eat white-tailed deer and small mammals such as rabbits, raccoons and, nutria.

Red wolves usually live in warmer places than gray wolves.  Red wolves used to live in the southeastern United States. However, by the 1980’s red wolves were almost extinct in the United States.  Scientists started raising red wolves in captivity and releasing them in North Carolina. Now, there are about 130 wild red wolves living in Eastern North Carolina. Maybe we can study them when we paddling through North Carolina next year!

Food for thought:

Have wolves ever lived your state?

Do wolves live in your state now?

What type of wolves were historically found in your state?

What caused wolves to become extinct in so many parts of the world?

Use the map below to help you answer these questions.

Fennel's Field Notes

Zzzzzz. Zzzzzz. Dave just told me that I snore. I have been sleeping on the floor in Dave and Amy's room. It is nice and warm in here. I am glad they are back. I found out that Dave went to a friend's wedding and Amy flew to Salt Lake City for a few days last week. That is why they left me in the retirement pen. I am really glad they are back.

This week has been great. I pulled the sled for the group that Dave guided. Well, I pulled part of the time when Dave needed me and then I ran along for part of the time. I spent a good amount of time sleeping too. I like sleeping inside.

I like eating too. Chicken has been on the menu lately. I like chicken. It is frozen and we get to eat big cubes of chicken. Mmmm. Mmmm.

Sulfide Mining Near the Boundary Waters

Through last week’s Cast Your Vote students decided that we should highlight mining near the Boundary Waters.  Mining inside the Boundary Waters Canoe Area Wilderness is not allowed.  However, several mining companies would like to build mines very close to the wilderness.  This type of mining is called sulfide mining, or strategic metals mining. One of the proposed mines, called Twin Metals, would be about 3 miles from the wilderness border. It is in the Boundary Waters watershed.  This means that lakes and rivers near the mine flow into the wilderness.  Polymet, which is another proposed mine, is in the Lake Superior watershed. This means that pollution from the mine could flow into Lake Superior and the Great Lakes.

Some people are excited about the jobs and money that the mines could bring to the towns near the wilderness. Some of this money could be used to improve schools and other things in the town. Other people are worried that the mines will pollute the water, cost a lot of money to clean up, and close after about 20 years.

Iron_hydroxide_precipitate_in_streamAmy and I are worried that the mines could pollute the water near the mines for thousands of years. No one knows exactly how long the mines will operate, but the Polymet Mine would be open for about 20 years.  However, when scientists studied the proposed mine they said that it could cause pollution for 2,000 years. Is it worth creating a bunch of jobs that last for 20 years if the mine causes pollution for 2,000 years after the mine closes?

Polymet has developed new ways of mining that they say reduce the risk of pollution. However, many sulfide mines have produced a lot of water pollution. Many have cost millions of dollars to clean up.  One study found that 76% of the mines that were predicted to not pollute ended up causing pollution. The proposed mines are in the middle of 5 million acres of lakes, rivers, and forests in Minnesota and Ontario.  These lakes and rivers contain some of the cleanest water in the world.

A class emailed last week to ask what they could do to help protect the wilderness. The copper and other metals that are produced in mines like these are used in many of the things we all use on a daily basis: computers, TVs, Xbox, batteries, and lots of other things.  One of the best things we can do for the environment is to try and reduce the amount of “stuff” that we buy and consume. Plus, we can recycle and reuse things as much as possible.  Can you think of things that you can do at school or at home that could help?

Amy and I feel that these sulfide mines are not a good idea because of the pollution that they could cause. We hope that you will do some more research and make your own decision.

Keep Exploring!

Food for thought:

Here are a few links to additional information about sulfide mining.

http://www.paddlinglight.com/articles/news-articles/sulfide-mining-near-americas-most-used-canoe-wilderness-area/

Research sulfide mining and the mines that are being proposed in Northern Minnesota. Break up into groups. Have one group that supports the mines, a second group that argues that the mines should not be built, and a third group that moderates the debate.

Are there any mines near where you live?  Research mining in your area and learn about the benefits and environmental issues that effect mining in your area.

What watershed do you live in? Use a map to it out.

Do you recycle at home and at school? Research what recycling is available in your area.

Use the links below to make a list of things you use everyday that are made from copper.  Brainstorm how you could make these things last longer, or ways you could reuse or recycle them.

Fennel's Field Notes

I watched Dave and Amy load their car a few days ago. I was happy about this, because it usually means that we are going on a trip. They put their bags in the back and climbed in. They told me to follow as they drove down the driveway. They stopped at the Wintergreen dog yard and walked with me to the retirement pen.

I tried to protest. I wanted to go on the trip with them. Riding in the car is fun! They didn't pay attention and they left me with Lufa and Patches in the retirement pen. Lufa can be kind of bossy, but I get along with those two for the most part.

As the days passed, I missed Dave and Amy. The other Wintergreen guides were nice to me. I got to run along on a few trips. Kate even let me take someone skijoring. That is a little confusing. I don't like to pull just one person by myself. I like to pull a sled with other dogs.

Chris told me that Dave and Amy are coming back soon. I can't wait!

What would you like us to make videos about?

DaveAmytentWe need your help figuring out what sort of videos to shoot while we are dogsledding in Minnesota! Please let us know what you would like to learn about – and what sort of videos you would like to see.  In the cold our camera battery doesn’t last very long, so we need to plan our video shoots in advance.

Thank you for all the creative ideas for last week's Dave's Dilemma. We will try all of your different suggestions for making Fennel's paw print to figure out what works best. We will announce the winner next week!

Our first Dave's Dilemma was about Fennel pulling a sled. We had many good responses to this dilemma too. It seems that most of you would like us to give Fennel a chance to pull a sled. We will let him pull and run as long as he seems to enjoy it.
