Rockcrawling
extreme type of recreational off-road driving / From Wikipedia, the free encyclopedia
Rock crawling is an extreme form of off-road driving.[1] Participants use vehicles anywhere from stock to highly modified to overcome obstacles (usually rocks). In rock crawling, drivers drive highly modified four-wheel drive vehicles such as trucks, Jeeps, and "buggies" over very harsh terrain. Driving locations include boulders, mountain foothills, rock piles, mountain trails, etc.

Rock crawling is about slow-speed, careful and precise driving, and high torque generated through large gear reductions in the vehicle's drivetrain. Rock crawlers often drive up, down and across obstacles that would appear impassable. Most vehicles used to rock climb are primarily 4x4s.
Rock crawling competitions range from local events to national series. A rock crawling competition consists of obstacle courses that are about 100 to 200 yards (91 to 183 m) long. Each obstacle is set up with gates, similar to a ski course. Usually a spotter (person who guides the driver) helps the driver through hard obstacles. Spotters may also use a rope to help prevent a vehicle from tipping over.[2]
