Boulder Dash (roller coaster)

Construction for the coaster began in June 1999 and was completed in May 2000.^[1] The ride cost $6 million and was built into the side of a mountain at Lake Compounce.^[2][3] In the four years prior to the ride's opening, Lake Compounce's owners had spent $40 million on improving the park. The opening of Boulder Dash helped increase attendance at Lake Compounce, which had suffered from declining attendance in prior years.^[2]

During the 2007 off-season, about 80 percent of the ride was retracked, and some of the supports replaced, as part of a $3 million renovation. In addition, the end of the ride, which had an intentionally uneven track, was rebuilt.^[4] Lake Compounce bought PTC trains from Hersheypark's Wildcat for the 2008 season. For the 2017 season, Boulder Dash was retracked by Martin & Vleminckx to help smooth out rough patches and replace rotting wood.^[5] The retracking also removed the triple-up hill located near the end of the ride, replacing it with a double-up hill.^[6] For the 2023 season, 580 feet of the track was replaced with steel Titan Track by Great Coasters International and Skyline Attractions.^[7][8] For the 2024 season, an additional 280 feet of track was replaced.^[9] Before the 2025 season, more than 200 feet of Titan Track was added to the unbanked right turn before the halfway turnaround.^[10]

The 4,672-foot (1,424 m) wooden roller coaster uses Lake Compounce's natural mountainous terrain, complete with trees and boulders within close proximity of the track.^[11] It is the longest wooden coaster on the East coast at 4,725 feet.^[12]

The lift hill climbs the mountainside and disappears from view. When it reappears, it has completed its first drop of 115 feet^[3][11] and is traveling sixty miles per hour as it crosses over itself and flies over the station. Much of the first half of the ride is hidden as the train climbs and drops along the mountainside.^[11] On the last drop, on-ride photos are taken and can be viewed and bought at the photo booth at the end of the exit line.

Boulder Dash features two six-car trains manufactured by Philadelphia Toboggan Coasters (PTC). Each car has two rows, and each row seats two riders, for a total of 24 riders per cycle. One of the trains is painted green and the other is painted blue. Both feature the ride's logo on the front of the lead car.^[11][13]

On June 13, 2001, a 23-year-old worker was killed after being struck by one of the coaster's trains.^[12][14] Occupational Safety and Health Administration (OSHA) officials subsequently visited Lake Compounce and found several safety violations, fining the park $29,000. In November 2001, this fine was halved as part of a settlement between the park and OSHA.^[15][16] The worker's family sued Lake Compounce in 2002 over the accident.^[17]

Boulder Dash was voted the world's top wooden roller coaster in 2001 by the National Amusement Park Historical Association.^[2][3] In addition, from 2001 to 2023, the ride was one of the top five wooden roller coasters as ranked by Amusement Today's Golden Ticket Awards. The 2004 Golden Ticket Awards was the first in which Boulder Dash was the top-ranked wooden coaster.^[4][18]
