The Maui Fire Department said a burnt-out truck was found in the site of a brush fire today in Waiehu.

The Fire Department used helicopters to help douse the 2-acre brush fire in old macadamia nut fields.

The cause was undetermined, but the blackened truck was located in the burn area, the department said in a news release. The area is known as a dumping ground for vehicles, the department said.

Wailuku fire crews investigated a report of light smoke and found the fire at 12 p.m. on the west side of Kahekili Highway.

The Fire Department launched Air 1 and later Air 2 due to trouble that ground crews were having in getting to the site due to overgrown brush.

A battalion chief, two engine companies and two water tankers also responded to the blaze.

The fire was brought under control at 2:30 p.m., and it was extinguished at 4:25 p.m.
