In 1971, Collins leased the park to the food service company ARASERV which added a few new rides including the Sky Ride, a chair lift that brought riders down to the Animal Land zoo that was situated near the Casino. On June 11 of that year, a natural gas explosion leveled the Tap Room and Stardust Ballroom building while the Holyoke High School prom was taking place inside. Two park employees died in the explosion and resulting fire. The Tap Room and Stardust Ballroom were never rebuilt.
