The Thompson-Ames Historical Society of Gilford seeks to preserve and share the history of Gilford, NH and its people. Particular emphasis is given to Gilford's agricultural history. The society operates three museum structures—the 1834 Union Meetinghouse, John J. Morrill Store of 1857, and the circa 1838 Benjamin Rowe House. The Meetinghouse holds local history exhibits which address religion, leisure activities, military history, and agriculture. The site also contains a Victorian period room and town hall and schoolhouse settings. Highlights include a horsehair sofa, ice fishing equipment, and an eight-foot traverse sled. The Greek Revival Morrill Store used to serve as the meeting place for a farmer's organization. The interior contains an 1800s homestead living room setting; an 1857 store setting; a circa 1940 kitchen; historic signs; musical instruments; and artifacts related to the Grange, New Hampshire government, and local theater. The Greek Revival Benjamin Rowe House is furnished to the style of the 19th and early 20th centuries on the ground floor and the 20th century on the upper floor.

The society offers exhibits, period rooms, tours, school tours, and archive access. Archival materials include transcriptions and recordings of oral histories.

"The earliest evidence of humans along Turnagain Arm is at Beluga Point, which prehistoric hunters used as a view point to search for Beluga whales and sheep. The first white explorers arrived in 1778 aboard Captain Cook's ships, Discovery and Resolution. Cook sailed up Cook Inlet hoping to find the Northwest Passage, but had to "turn again", leading him to name the water body River Turnagain. In the late 19th century, miners and trappers began traveling into interior Alaska from Whittier and Seward along old trails that soon became established routes with roadhouses. In 1895 prospectors crossed from the south side of Turnagain Arm to the north and searched for gold from Girdwood to Rainbow Creek.

In 1903, the Alaska Central Railway began building a railroad from Seward to Fairbanks, but the company soon went bankrupt. The U.S. Government bought the railroad in 1915 and improved the trail along the arm to handle the horse and wagon traffic needed for railroad construction. The trail was also used to deliver mail between Anchorage and Seward. IN 1917 telegraph lines were laid along the Turnagain "road" and by 1918 the railroad extended from Seward to Anchorage, with flag stops at Bird Creek, Indian, Rainbow and Potter. Remnants of construction camps remain along the trail, but are barely discernible. Part of the original trail was covered by the highway which was completed in 1950 and paved in 1954."

Six miles west of Redding, a row of old, half-ruined, brick buildings remind passing motorists that Shasta City, the lusty "Queen City" of California's northern mining district, once stood on this site. These ruins and some of the nearby roads, cottages, and cemeteries are all silent but eloquent vestiges of the intense activity that was centered here during the California gold rush. Iron shutters still swing on massive, old, iron hinges before the doors and windows of grass-filled, roofless buildings that once were crowded with merchandise, and alive with the human sounds of business, trade, and social endeavor. The County Courthouse is restored to its 1861 appearance, the year when it was converted from commercial uses to become the Shasta County Courthouse. Today the building is filled with historical exhibits, and an unparalleled collection of historic California artwork that make it the central figure of Shasta State Historic Park.

The park offers exhibits, tours, demonstrations, and occasional recreational and educational events.
