Yellowstone Wildfire Grows But Still Being Allowed to Burn

A wildfire burning in the central part of Yellowstone National Park has grown and is putting up more smoke.

However, park officials say it is not threatening any structures or roads and is being allowed to burn for now.

The fire was started by lightning on Wednesday.

It is the biggest of two fires burning in Yellowstone.
