The Chesapeake & Potomac Invitational Bonspiel (aka: Meltdown) began in 1983 as a competition between the Potomac Curling Club and the Chesapeake Curling Club. At the time of founding, Potomac was playing on rented hockey ice, and the newly established Chesapeake Curling Club had dedicated curling ice. The two clubs jointly hosted the original bonspiel. Since that time, the clubs have alternated the hosting of the event.
The 2015 CPIB has been canceled due to the impending snowstorm.
