Peak Fire in San Bernardino National Forest off Highway 18 fully contained

A fire sparked earlier this week off Highway 18 in the San Bernardino National Forest was fully contained, officials announced Thursday.

The fire broke out on Monday amid hot and dry conditions that struck the region. One firefighter was taken to a local hospital for a heat-related injury, fire officials said. On Monday, fire crews were also up against low humidity and triple-digit temperatures

The fire, named the "Peak Fire," was held by crews at about 35 acres and was 100% contained by Thursday morning. Officials believe the blaze may have come from a car fire off Waterman Canyon near the highway.

An estimated 150 firefighters and 14 pieces of aircraft with the US Forest Service, along with San Bernardino County Fire, responded to the fire.

Evacuations were not ordered, but crews protected more than a dozen nearby homes that were in the path of the fire.

Fire officials were worried about storm clouds building around the mountains, due to the possibility of dry lightning, during the next few days. With that in mind, the public is being asked to be overly cautious and report anything they see immediately.
