Thunder Mountain Speedway is a three-eighths-mile banked clay oval hosting weekly stock car racing on Saturday nights from April through September. The speedway has undergone numerous improvements since Karl Spoonhower returned to ownership in 2013, including the complete resurfacing of the track’s clay, an expanded/reconfigured turn three, a reworked entrance road, new lighting and a general clean-up of the concession stands, bathrooms, and the facility.
Thunder Mountain offers a family atmosphere, stadium-style concrete hillside seating for 2,500 spectators, concession stands offering delicious food items, novelties and more. Parking and camping on the premises are always free. All seating is general admission. Tickets are sold at the gate on race night.
Weekly racing at Thunder Mountain is headlined by the powerful big-block/small-block Open Modifieds with or without sail panels. Other regular divisions include Crate vs. Open Sportsman, DIRTCar Sportsman, DIRTCar 358 Modifieds, 600cc Modifieds, Street Stocks and Factory Stocks.
