    > Announcing the 7th Annual Ice-Out Contest for Walden Pond
    > When do you think the ice will melt on Walden Pond this spring? Famous naturalist Henry David Thoreau, a Concord Village resident of the 19th century, wrote of simplicity, economy of living, finding your own way in life, and watching the natural environment around you. He lived out in the woods in what is today Walden Pond State Reservation. Thoreau kept ice-out records in the mid-1800s and recorded them in his celebrated book, WALDEN.

    > As you prepare your prediction for ice-out, you might wonder: Why did Thoreau choose to go live in the woods from July 1845 to September 1847? In his writings about Walden, he explains: "I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived."

    > Here's the latest news from Park Supervisor Michelle Dumas at Walden Pond State Reserve. We hope it will help you predict the 2001 ice-out date for the Pond:
    >
    > "Hello, Journey North students! All is winter here! The temps have been colder than normal...in the teens. We have had more snow this past January and February than we normally do. On February 5 we picked up another new foot of snow. The ice fisherman reported yesterday that we had about 12 inches of ice on the pond...that's a lot for us. Today is 35 degrees with a lot of rain.
    >
    > "One of the best times to visit the ice on Walden is during the early morning when there is total silence except for the great creaking, cracking and thumping noises the ice on the pond makes. I have had the pleasure of listening to Walden's song many mornings and so did Thoreau. He wrote, "The pond began to boom about an hour after sunrise, when it felt the influence of the sun's rays slanted upon it from over the hills; it stretched itself and yawned like a waking man with a gradually increasing tumult, which was kept up three to four hours."

    Dear Journey North,

    Our Walden Pond ice out guess is March 13. Personally, I would have guessed a little later but we took the class average and that brought us to the 13th. Wish us luck.

    Thanks.
