At 3:30 one morning in July 1932 a man named Bob Marshall went t as many peaks in the Adirondack Mountains as he could in
one day. Bob M loved to walk and he loved to write after that. He loved facts, too. He knew that he'd climbed 13,600 feet that
day. He kept statistics on everything.
But most of all, Bob Marshall loved wilderness — natural lands with no J roads,
1 or towns. When he wasn't walking in the
wilderness, he was working to save it. By the time he died, at the age of thirty-eight, he had written important books and articles
on the protection of nature, he had helped to form the Wilderness Society, a group that works to protect wild lands.
Today, a great area of wilderness in Montana, where he often walked, is the Bob Marshall Wilderness Area.
Robert "Bob" Marshall was born on January 2nd, 1901. When Bob was years old, he climbed his first mountain. Every summer
after that, he a brother explored the Adirondack forests. Bob always wanted to be a forester. His dream came true. He worked in
Montana and Idaho, where he met a grizzly bear He lived in Alaska for over a year. There he explored on foot and by boat; hi to
all-night dances with the Eskimos. Then he wrote a book called Arctic V He got money for the book and shared it with the
villagers (each person got In the 1930s roads appeared across wild lands. People cut down forests. Bob MARSHAL thought that
forests were also to enjoy. In a magazine article he explained why some lands should stay wild. He wrote the rules that didn't let
people build on many wild lands, and he also worked to make picnic grounds and ski areas to people from cities to the beauties of
the wilderness. перевод, пожалуйста
