Riverside Lodge # 124 is located in the historic town of Cass, Pocahontas County, West Virginia. The town of Cass was originally started as a sawmill and lumber town in the rugged, remote mountains of West Virginia. The men who worked for the timber company, variously know as "hicks", were a rugged and rowdy lot, who came to town from the logging camps on the weekends or whenever they could get time off. As a result, the town of Cass was the scene of numerous gambling, drinking and other immoral activities, including robberies and murders. In an effort to curtail the crimes and immorality of Cass, the more virtuous citizens of Cass began to introduce and organize moral institutions for the local citizens, among the first of which was the Riverside Lodge # 124, A.F. & A.M. (the Masons).

Riverside Lodge # 124, Ancient Free and Accepted Masons, under the Grand Lodge of West Virginia, was chartered on November 12, 1903. The first Master of the Lodge was George L. Eakle. The initial Lodge meetings were held in the Austin Building,located in East Cass. The West Virginia Spruce Lumber Company, realizing what a major positive impact Riverside Lodge # 124 was making to the town of Cass, deeded a plot of land to the Lodge on February 7, 1907, for the construction of a new Lodge building. The new Lodge building was constructed, at a cost of $1,500, on the land plot located on Front Street in Cass. The building was originally 24 feet wide by 48 feet long by 24 feet high, and a smaller addition added later. The original Lodge building still stands and serves as the current Lodge building.

Riverside Lodge # 124 has always maintained a commitment to mankind, as evidenced by some of the early activities held at the Lodge:

Approximately 1914, Dr. Hammond set up a dental office in a small backroom of the Masonic Hall. In 1926, Dr. Hammond was succeeded by Dr. Gregg of Durbin. Dr. Gregg's office was upstairs in the back of the Masonic Hall and was open two or three days each week.

During World War 1, the Red Cross appealed to the public to supply bandages for the soldiers. In January 1918, a Red Cross bandage sewing station was set up in the front room of the Masonic Lodge. In April 1918, it was moved upstairs and the post office and Pocahontas Supply Office was located temporarily in the front room of the Masonic Lodge, after the PocahontasSupply Company burned on March 11, 1918.
