Icon Legend

John Wingate Weeks Historic Site's Mt. Prospect estate was built at the direction of John Wingate Weeks, leading conservationist, U.S. congressman, U.S. senator, and Secretary of War under Presidents Harding and Coolidge. The 420-acre Mt. Prospect estate was given to the state of New Hampshire in 1941 by John Weeks' children, Katherine Weeks Davidge and Sinclair Weeks. Set at the very top of Mt. Prospect in Lancaster, New Hampshire, the house and grounds provide a 360-degree panorama of mountain splendor, including the Presidential Range of the White Mountains, the Green Mountains of Vermont, the Kilkenny Range, the Percy Peaks, and the upper Connecticut River Valley. Enjoy a historic Tower and the Lodge.

2011 marked the 100th Anniversary of the historic Weeks Act. Enacted in 1911, the Weeks Act enabled the aquisition of over 19 million acres in 124 national forests, spanning 42 states, including the White Mountain National Forest in New Hampshire and Maine. To honor this occasion was created by a diverse group of organizations. This website, hosted by NH Public Television, is an aggregation of the many events, stories, lectures and research about the importance of our nation’s forestlands and the role they play in the quality of our lives, as well as about the Weeks Act, the White Mountain National Forest, and the International Year of the Forest. Explore the site and read up on Weeks Act history, news, multimedia, events, links and to share your comments as well.
