SALMON-CHALLIS NATIONAL FOREST, Idaho (CBS 2) -- The Hayden Fire burning 18 miles west of Leadore has burned 17,446 acres.

The fire started on Wednesday, July 19th. Fire managers said crews are working long hours every day to contain the fire as quickly as they can, impacting the fewest acres possible.

On Friday, weather conditions brought cooler temperatures and cloud cover allowed firefighters an opportunity to make good progress on containment lines. On Saturday, fire operations will be implementing a “swing shift” which will enable firefighters to work into the late hours of the night to make additional progress when fire conditions are more favorable.

Burnout operations to build depth to containment line are planned for the northern portion of the fire near Bear Valley Road.

“The firefighters assigned to the Hayden Fire are working extremely hard to extinguish this fire, protecting the surrounding communities, stakeholders, and public lands is their priority," said Mike Johnston, Incident Commander of Great Basin Team 7. "I appreciate their hard work, dedication and the support shown by the community.”

700 personnel are working on the fire. It is 0% contained as of Saturday morning.

The Lemhi County Sheriff’s Department in coordination with the Salmon-Challis National Forest and Great Basin Team 7 have pre-identified evacuation zones. They will be implemented using the “Ready, Set, Go” terminology. For more information, visit the Lemhi County website at lemhicountyidaho.org.

The Salmon-Challis National Forest has an area closure order in place to help protect firefighter and public safety. Maps and additional information are available on the Alerts and Notices SCNF website.
