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. Bentley, pioneered the technique of photomicrography and was the first person to photograph a single snowflake. The entire lower level of the building displays priceless mementos of "Snowflake" Bentley, original milling machinery, and the products of Jericho's water-powered mills.

The mill offers exhibits and tours.

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.

The Society oversees the care of the Kruse House Museum. The Kruse House is a 1917 four-square home depicting the Fred Kruse family lifestyle.

The backyard boasts a period garden which has been restored and is being maintained by the West Chicago Garden Club.
