On June 22, 2000, at 2100 hours Pacific daylight time, a Cessna 206, N511RB, collided with a dirt berm during an attempted takeoff from a pasture 16 miles north of Gerlach, Nevada. The airplane was operated by the owner/pilot under the provisions of 14 CFR Part 91, and sustained substantial damage. The private pilot, the sole occupant, was not injured. Visual meteorological conditions existed for the personal flight, and no flight plan had been filed. The flight departed Boise, Idaho, at an unknown date and time, and was scheduled to terminate at the Santa Monica Municipal Airport, Santa Monica, California. The reason for the en route stop in the pasture was undetermined. The accident was reported to the National Transportation Safety Board on June 26, 2000, after verification of damage by a Federal Aviation Administration (FAA) inspector. Repeated attempts to reach the owner/pilot for additional information concerning the accident were unsuccessful.
