The Adventuredome, formerly known as the Grand Slam Canyon, is a 5-acre (2.0 ha) indoor amusement park located at Circus Circus in Las Vegas, Nevada on the Las Vegas Strip. The park is connected to the hotel inside a large glass dome, and currently offers 25 rides and attractions including the Canyon Blaster roller coaster, rock climbing wall, 18-hole miniature golf course, an arcade, clown shows, Xtreme Zone, Pikes Pass, Virtual Reality Zone, Midway Games, and carnival-type games. Because the park is enclosed, it is not affected by cold, rainy, or windy weather, unlike most theme parks, and is open year-round. Every October since 2003, the Adventuredome is changed to Fright Dome as a Halloween-themed theme park.
The Adventuredome opened on August 23, 1993 in the west parking lot of the hotel. It sits on a reinforced 18" thick deck elevated 18 feet (5 m) above ground. The dome itself consists of over 350,000 sq ft (33,000 m2) of pink tinted, insulated glass over a teal green space frame (to minimize structural poles inside). Each pane of glass weighs approximately 300 lb (140 kg).
Previous owner of Adventuredome was Mandalay Resort Group, formerly known as Circus Circus Enterprises (1993–2005)(Wikipedia)
