South Dakota firefighters battling a blaze on Black Hills, which briefly forced the closure of the Mount Rushmore National Memorial and prompted the evacuation of hundreds of homes, made progress overnight.

A statement Thursday on the official Schroeder Fire Facebook said that the area's largest fire near Schroeder Road, in the Nemo area, is now around 47% contained and has burned 2,195 acres.

Authorities said Monday that the fire was human-caused.

In an update on Thursday, the firefighters wrote that dry and windy conditions that have helped stoke the flames were expected again. They also said that while they have worked to extinguish "hot spots near structures," the area is under a Red Flag Warning through Thursday night.

"Our firefighters need your help today: Please avoid outdoor use of fire, or anything that could make sparks," they pleaded. "Together, we can prevent another new fire."

At least one home was destroyed in the neighborhoods southwest of Rapid City, but no injuries have been reported, according to The Associated Press.

But there was some good news for those returning to evacuated areas as the Pennington County Sheriff's Office said Thursday they were working on a plan to reopen travel on nearby West Highway 44, following reports of active fire near the highway on Wednesday night.

"Nameless Cave and Cleghorn Canyon areas will remain closed through tonight (4/1/21) and will be re-evaluated Friday morning," they noted in their own Facebook post.

While KELO reported that firefighters were still working on the 244 Fire ‒ one of two smaller fires, the other being the Keystone Fire ‒ in the Mount Rushmore National Memorial area, the memorial announced on its Facebook page Thursday that they are open as firefighters "continue mop-up operations."

A government incident page said the 244 Fire had spread over 136 acres and is 75% contained. Heavy airtankers and helicopters supported ground firefighters in their effort.

Iron Mountain Road ‒ an alternative route fo the memorial ‒ will remain closed through the day.

"Fire response in the Black Hills relies on the interagency collaboration and the coordination of Resources by the Great Plains Interagency Dispatch Center in Rapid City," Mount Rushmore National Memorial Superintendent Michelle Wheatley said in the post. "We are grateful to the multiple agencies and firefighters that provided a swift response enabling the reopening of the park."

On March 30, Republican Gov. Kristi Noem declared a state of emergency through June 1 due to severe drought and dangerous fire conditions in the state.

Noem traveled to survey the damage from the Schroeder Fire on Tuesday.

"The order will allow the state to provide greater assistance to the response efforts of local and volunteer firefighters," Noem's office said in a release. "Governor Noem has spent the past two days overseeing the response to the Schroeder Fire outside Rapid City while monitoring other fire incidents."
