log-rolling dock, two competitors run head to head on adjacent booms. Each competitor must step off the logrolling dock, running across a chain of logrolling logs to the chopping dock, circling a specified competition station and cross the pond on the boom logs back to the logrolling dock. The competitor must step onto the logrolling dock and touch the starting point. This is a timed event and is timed to the tenths of a second. Anyone leaving before the word "go" will be assessed a 10-second penalty. Men's events Underhand block chop Using a five-pound single-bit axe, competitors chop through a horizontal aspen log in diameter and long. Timing begins on the signal "go" and ends when the log is severed. A new world record was set in 2006 by Jason Wynyard with a time of 15.94. In 2007, competitors moved from the underhand chop to the standing block chop for one continuous timed event known as the endurance event. Standing block chop Using a five-pound single-bit axe, competitors chop through a vertical standing aspen log in diameter and long. Timing begins on the "go" signal and ends when the log is severed. This event was combined with the men's underhand chop as the endurance or combination event in 2007. Competitors moved from the underhand chop to the standing block chop for one continuous timed event. The world record for the standing block chop is 12.33 seconds set by Jason Wynyard from New Zealand in 2007. Springboard chop This event combines the skills of the chopper and the high climber. Out in the forest this technique enables a working lumberjack to reach softer wood above the tough and knotty base of a tree marked for cutting. Contestants climb a height of nine feet using two springboard placements and chop through a aspen log mounted on the top of the spar pole. Dave Bolstad set a new world record of 41.15 in 2003 besting his previous world record time of 41.63 in 2001. Single buck A single sawyer uses a one-man bucking saw to cut through a white pine log for the best time. Dion Lane set a new world record in 2006 with a time of 10.78 seconds. Hot saw A single sawyer using a single-cylinder, single-motor power saw makes three vertical cuts—down, up and down—through a white pine log. This one-man contest is strictly against time. Chain saws may
