WHITMAN COUNTY, Wash. -

The Palouse wildfire season got off to a fast, hot start Tuesday. 

One of the largest early-season wildfires in years broke out mid-afternoon near Swift Bar along the Snake River.

Volunteers from three Whitman County fire districts ended up battling the flames for about seven hours. 

Flames grew from Swift Bar into adjacent canyons as the fire burned up Penwawa and Long Hollow Roads. 

High winds and steep terrain caused the fire to grow to about one thousand acres before crews got a handle on it early Tuesday night. 

There is no word on what caused the fire and no structures were threatened.
