A fire rampaging through Jasper National Park remained out of control Wednesday, while officials worked to restore power and water in the park含羞草研究社檚 townsite and to hash out a plan for vacationers to retrieve their stranded camping trailers.

含羞草研究社淭he wildfire is still very active,含羞草研究社� Mike Ellis, Alberta含羞草研究社檚 public safety minister, told an online news conference.

Work continued on multiple fronts. Ellis said crews on the ground and in helicopters were battling flames, with air tankers on standby.

He said a plan was being formulated and should be ready in the next day or so to help people get the campers and trailers they were forced to abandon when everyone was ordered out of the park.

The stretch of Highway 16 through the park was soon set to reopen to heavy commercial traffic.

含羞草研究社淭his is an important economic corridor,含羞草研究社� Ellis said.

Alberta Forestry Minister Todd Loewen said the firefighting is expected to become more challenging in the coming days as hotter, drier, windier weather is forecast.

Flames that destroyed a third of all structures in the Jasper townsite have been extinguished.

Parks Canada said in a statement that 750 people are involved in the firefighting effort, with the focus on making sure fire does not re-enter the picturesque Rocky Mountain community.

The 5,000 residents of the town, along with about 20,000 visitors, were ordered out on a moment含羞草研究社檚 notice on the night of July 22. Two days later, fire whipped by strong winds overwhelmed crews and rolled into the southern edge of town, destroying 358 homes and businesses.

Critical infrastructure survived, and the town was flushing waterlines and restoring power.

Parks Canada also said municipal teams were retrieving lost pets in the town.
