A walk through historic Greenwood Furnace evokes images of the community that flourished here from 1834 to 1904.

Today, the park covers 423 acres, including a six-acre lake, and is surrounded by an 80,000-acre block of Rothrock State Forest. Interpretive programming at the park is centered on the former Greenwood Furnace and the company town that grew up around it.

Staatsburgh is a New York State Historic Site located within the boundaries of Mills-Norrie State Park. It provides an example of the great estates built by America's financial and industrial leaders during the Gilded Age. A 25-room Greek Revival structure was built on the site in 1832 by Morgan Lewis and his wife, Gertrude Livingston, replacing an earlier house that had burned down. This second house was inherited by Ruth Livingston Mills, wife of noted financier and philanthropist Ogden Mills. In 1895, Mr. and Mrs. Mills commissioned the prestigious New York City architectural firm of McKim, Mead, and White to remodel and enlarge their Staatsburg home. After completion in 1896, the house was transformed into a Beaux-Arts mansion of 65 rooms and 14 bathrooms. Its exterior was embellished with balustrades, pilasters, floral swags, and a massive portico. The rooms were furnished with elaborately carved and gilded furniture; fine oriental rugs; silk fabrics; and a collection of art objects from Europe, ancient Greece, and the Far East.

The site offers tours and educational and recreational programs and events.

The Society was formed in 1972 to perpetuate the mission of preserving the rich history of Jericho, Vermont, and the legacy of Wilson "Snowflake" Bentley. The Society's 1885 headquarters is located in the historic Chittenden Mills, a national historic site. The Old Red Mill, as it is known, houses a milling museum, art gallery, craft shop, and is also the home of the "Snowflake" Bentley Exhibit. Native son, Wilson A.

The Society operates two house museums. The 1872 Lee House was home to Dr. Norman Lee, one of Junction City's first doctors. It was originally located in Lancaster and was moved to its present location in the late 1800s using logs and a team of horses; it now displays photos, furniture, tools, and clothing from Junction City's past. The 1871 Pitney House belonged to Mary Pitney (1891—1995), a school teacher, published poet, painter, world traveler, and humanitarian. Born and raised in this house, she lived the later years of her life here; today, it is being restored and features a room devoted to Danish historical artifacts from Junction City's first settlers, a cutaway of the home in the kitchen so visitors can see how buildings were constructed in that time period, and Mary's original furniture in the living room. Next door to the Pitney House is the first jail, built in 1873.

The houses offer exhibits, tours, and occasional recreational and educational events.
