BOISE, Idaho — The mountainous conditions in the Pacific Northwest will be nothing new to the dozens of firefighters from Australia and New Zealand who have arrived to help battle the many blazes burning unchecked in the region.

“We’re used to tall timber and steep territory,” said Warren Heslip, a 47-year-old firefighter from Southland, New Zealand.

Heslip was among the 71 firefighters from the southern region picking up equipment Monday at the National Interagency Fire Center in Boise, Idaho, before heading out to help a ground campaign led by firefighters from across the West and augmented by U.S. soldiers.
