The Mount Independence and Hubbardton Battlefield Vermont State Historic Sites open for the 2011 season on Saturday, May 28, at 9:30 a.m. Both sites have scenic grounds for walking and picnics, and popular specialty museum shops with many books and other items.

The Chimney Point State Historic Site and grounds in Addison will be closed to the public for the 2011 season due to the ongoing construction of the Lake Champlain Bridge. The site will be open for the bridge opening celebration weekend, at a yet to be determined date this fall. The popular annual Northeast Open Atlatl Championship, September 16 to 18, will be moved again this year to Mount Independence in Orwell.

Orwell, Vermont’s Mount Independence, a National Historic Landmark named after the Declaration of Independence, was built on Lake Champlain in 1776-77 to protect the American colonies against British invasion from the north. This year is the 235th anniversary of the start of construction, as well as of the Mount Independence-Hubbardton Military Road.

The museum’s exhibits include a talking hologram sculpture and exciting Revolutionary War artifacts from the site, including two huge logs from the Great Bridge and a cannon recovered from Lake Champlain. Six miles of scenic walking and hiking trails wind past archaeological sites. The nationally award winning Baldwin Trail is suitable for outdoor wheelchairs and strollers, and has acclaimed interpretive signage.

The season begins on Saturday, May 28, at 8:00 a.m. with the favorite annual Early Bird Nature Walk, led by bird expert Suzanne Wetmore. Other special events include nature and history programs and the annual Soldiers Atop the Mount encampment on July 23 and 24. The site is open daily, 9:30 to 5:00. Admission is $5.00 for adults and free for children under 15.

The Hubbardton Battlefield State Historic Site is the location of Vermont’s only Revolutionary War battle. It is considered one of the best preserved battlefields in America, retaining most of its original setting, and is on the National Register of Historic Places. At noon on May 30 there will be a simple Memorial Day commemoration.

The annual living history weekend, with the battle reenactment, is July 9 and 10, with many other nature and history programs and hikes throughout the season. The site is open Thursdays through Sundays and Monday holidays, including Memorial Day, from 9:30 to 5:00. Admission is $2.00 for adults and free for children under 15.
