A fire that began Wednesday on private land near Powder Mountain Ski Resort about 25 miles east of Ogden, spread Friday, while crews near Vernal built lines around a fire that has consumed more than 200 acres.

The Powder Mountain fire, which had destroyed 350 acres of timber Thursday night, grew to 500 acres by Friday afternoon, said Bill Brooks, Interagency Fire Center dispatcher in Salt Lake City."They did some back-firing and that accounted for some of it," Brooks said.

Just 20 people were working the fire."They are exhausted - they've been on it for two days and there's no one to replace them," Brooks said.

Meanwhile, light afternoon rain Friday helped firefighters battling the 200-plus acre fire 20 miles north of Vernal on U.S. 191, said Merle Young, Ashley National Forest spokeswoman.

The blaze, which began Wednesday was 80 percent contained by 6 p.m. Friday and Young estimated the fire will be completely contained Saturday. "We have restored power to Deer Lodge and kept U.S. 191 open, clearing away some burned timber beside the road that might have fallen over onto the highway."

Young said there has been no property damage and 28 mountain homes three quarters of a mile from the fire have been protected. "We saved a microwave site on Grizzly Ridge a quarter mile from the fire, too."

Meanwhile, firefighters battling a 30-acre blaze near Teepee Lakes in the Uinta Mountains Friday were having difficulty getting equipment to the remote area.
