ADDISON As the school year starts teachers are reminded of the great, educational field trip opportunities this fall at the Chimney Point, Mount Independence, and Hubbardton Battlefield State Historic Sites to learn about archeology, state, national, and even world history. The sites are open through Columbus Day. At Chimney Point in Addison, students can discover how to use archeology to learn about the Native American and French Colonial history of Vermont and the Lake Champlain area. There are two hands-on programs to choose from. The highlight for every group is learning how to use the atlatl, the Native American spear thrower. Call 802-759-2412 to schedule a visit. The site is open Wednesdays through Sundays and Monday holidays. Mount Independence in Orwell is one of the best preserved Revolutionary War archeological sites. The site offers an informative hands-on ox cart activity program, an interactive visit to the museum with state of the art exhibits, and six miles of walking and hiking trails, including the new Baldwin Trail with engaging interpretive signage. An education kit is available for use in the classroom for a $25 fee. The site is open daily. Call 802-948-2000 to reserve your trip. The Hubbardton Battlefield in Hubbardton is the site of the only Revolutionary War battle fought in Vermont, and was where the northern American army was saved, so it could eventually beat British Lt. Gen. John Burgoyne at the battles of Saratoga. School visits include lively interpretation and stories from the site interpreter, and a guided tour of the battlefield. The site is open Thursdays through Sundays and Monday holidays. Call 802-273-2282. All school visits are $1 per student.
