The Cascade Fire grew to about 35 acres overnight. On Thursday morning, the fire was visible from California 89 above Emerald Bay on the south shore of Lake Tahoe.

Officials asked motorists in the Emerald Bay area to keep moving, though it is tempting to pull over for a view of the fire. Traffic controls will be put into place Thursday, said Cheva Gabor, a U.S. Forest Service spokeswoman.

The fire is burning above Cascade Lake in the Snow Lake area of the Desolation Wilderness, the Forest Service said in its news release. It was reported Wednesday afternoon.

The fire was human-caused, Gabor said. The exact cause is under investigation.

Crews are working to extinguish the fire with a helicopter making bucket drops. They also are using hand tools, chain-saws and pumps capable of drawing water out of nearby water sources to extinguish the fire, officials said.

No injuries are reported, or no buildings have been damaged.

The fire's cause is not known.

"This wildfire is not related to the King Fire currently burning west of Lake Tahoe," the Forest Service said in its statement.

FIRE RESTRICTIONS

-- With the King Fire still burning, the Forest Service is asking people to remember that fire restrictions are still in place in the Lake Tahoe Basin and to abide by those restrictions.

-- Fire restrictions mean that no open fires or campfires are allowed outside of campgrounds with an on-site host.

-- Campfires are never allowed in the Desolation Wilderness, only portable stoves are allowed with a valid campfire permit.
