Summary

The Jack Fire started on Oct. 29 from lightning associated with thunderstorms moving over the Park. The Jack Fire is located on the north and south sides of Turner Ridge north of Wawona. It was originally placed under wildland fire use management for resource benefits and public safety. On Nov. 8, the fire spread outside the fire use management zone causing a change in strategy. At this point, management actions were taken to slow fire spread south toward Wawona. Due to these management actions and cooler temperatures, very little fire activity was observed after November 12. However, as drier conditions were restored last week the fire began to spread significantly. Successful management actions, including burnouts and hand line construction, have held the fire at the Wawona Road and north of the community of Wawona. The fires this year in Lake Tahoe and Southern California are a reminder that is important to use fire as an ecological restoration tool as well as to create defensible space around fire prone communities.

How fires get their names

Every year in California thousands of wildfires start throughout the state. In most cases, the dispatch center sending the initial resources to a wildland fire will designate a name for the fire, but the first on scene engine or fire official can also name the incident. Fires are usually named for the area in which they start – a geographical location, local landmark, street, lake, mountain, peak, etc. Quickly naming the fire provides responding fire resources with an additional locater, and allows fire officials to track and prioritize incidents by name. For example during the Southern California Fire Siege of 2003, the largest wildland fire in California history, the Cedar Fire in San Diego County, was named after the Cedar Creek Falls area where it started. The destructive Old Fire, which burned during the same time period in San Bernardino County, was named after the road along which it started - Old Waterman Canyon Road.
