POMEROY, Wash. – Fire crews continue to work on gaining control of a 3,100 acre wildfire burning near Pomeroy in Garfield County Sunday morning.

As of 9:30 p.m.., the Snake River Fire has burned 2,500 acres and is burning mainly grassland. Officials said the fire began on Saturday morning around 1:30 a.m. on the west side of the river about 15 miles east of Pomeroy.

Authorities believe lightning started the fire.

Efforts for Sunday are to keep the fire on the river's slope and away from homes and cropland. They said mostly hand crews will attack the fire due to steepness of the terrain and the difficulty for engines to maneuver around. No evacuations are in place at this time for the fire.

A type three team is now on hand to assist in the fire. Authorities said difficult terrain and weather taxed several firefighters on Saturday and demonstrates another set of challenges facing suppressing the fire.

The fire is located approximately 4 miles down the Snake River from Chief Timothy Park directly across from Nisqually John Landing.
