Did you know that no two snowflakes are alike? Both Henry David Thoreau (1817-1862) and Wilson Bentley (1865-1931) loved to observe snowflakes! “Snowflake Bentley,” as Wilson was called, was even the first person to photograph them! Come celebrate these “six-rayed snowy stars” by joining park staff in some snowflake making. This activity will be held inside the new Walden Pond Visitor Center. The program is good for all ages.
