A small wildfire is still burning in Shenandoah National Park, and dry conditions continue to cause high fire danger in the park and elsewhere in the D.C. region.

The Millers Head Fire is located near Skyland, on the eastern side of Skyline Drive. The fire has burned about 2.5 acres and is 60% contained as of Wednesday morning, with about a dozen fire personnel working to put it out. The blaze was first reported on Friday.

Visitors to the park have not been affected, says NPS spokesperson Carly Adams.

“The fire is in very steep terrain, so it’s not close to any facilities or trails, and we don’t have any facility or trail closures in place,” Adams says. Smoke was visible in some parts of the park over the weekend, Adams says, but has since cleared up.

Firefighters from NPS, the Virginia Department of Forestry, the U.S Forest Service, and a crew from Colorado have established a fire line around the blaze, and are now working to put out hot spots. Firefighters used hand tools to dig trenches around the fire to keep it from spreading.

Rainfall in recent days helped with efforts to put out the fire. However, there is still a major rain deficit in the park — during July and August, there was less than two inches of rain at the park’s Big Meadows weather station. For the year, the park had 25 inches less rain than normal.

In late August, park officials closed all streams in the park to fishing, due to extremely low water flow. It’s an effort to protect fish, which are already stressed by high water temperatures and low levels of dissolved oxygen.

Officials are also asking visitors to be very careful with campfires.

Campfires have not yet been banned in the park, but they are only allowed in designated fire pits or grills. Park officials say visitors should make sure campfires are extinguished before leaving — you can douse a fire with water, then stir the ashes together with dirt.

No official cause has been determined for the Millers Head Fire, but Adams says initial reports suggest it was naturally ignited.

Wildfires were historically a natural part of the landscape in the Appalachian Mountains, however, fire suppression efforts have made wildfires much less common. This has had detrimental effects on ecosystems, leading to a decline of some species, including many oaks and pines, that depend on fire to regenerate.

NPS asks visitors to report any smoke or fire in the park at 800-732-0911. Updates on the Millers Head Fire can be found on an interactive NPS map, and on Shenandoah’s Facebook and Instagram pages. You can also check an NPS webcam for fire activity.
