The City Creek Canyon fire is now 70 percent contained, fire officials said Wednesday afternoon.

Fire crews continue to attack the blaze using air tankers, helicopters and ground crews hiking into the canyon to create a line around the blaze.

"We have some line established," said Jason Curry with the Utah Division of Forestry, Fire and State Lands. "There is quite a bit of retardant laid down and we're working on reinforcing that with hand crews."

But as temperatures rose again today, firefighters said to expect columns of smoke to be visible for a second day. The U.S. Forest Service has said it could be at least a day or two before the fire is declared fully contained.

"It's burning under that oak brush and dead leaves and stuff," said Kathy Jo Pollock with the Wasatch-Cache National Forest.

The fire has burned about 135 acres of land owned by Salt Lake City's public utilities, authorities said. No homes have been threatened, but the fire is burning in an area near some radio communications towers.

Gov. Jon Huntsman Jr. is expected to visit the fire this evening, Pollock said.

The fire is believed to be human caused. This morning, investigators are expected to travel to the scene where the fire started to begin looking for clues as to who might have started the blaze.

Air tankers, helicopters and ground crews have been deployed to the remote scene, which is accessible mostly by foot.

"We have no engine access," Curry said. "But we have fairly good foot access."

The City Creek Canyon loop road is closed, as are all of the popular trails going up the canyon. The upper part of Memory Grove Park is also closed.
