SAN MARCOS, Texas (KXAN) — Hays County leaders said a structure fire sparked a brush fire that burned through five acres west of San Marcos on Friday.

The fire, which started around 11:30 a.m. near the 900 block of Morningwood Drive, affected no homes but did burn an outbuilding, fire crews said.

“The Morningwood incident began as a structure fire but the blaze jumped to a neighboring property behind the outbuilding,” Hays County Fire Marshal Mark Wobus said.

“There were no homes or other structures directly behind the location where the fire began.”

The fire burned for about four hours, but no one was injured, Wobus said.

Multiple fire departments from San Marcos, Hays County and Kyle teamed up to battle the blaze.

“We want to thank all of our partner agencies that responded and worked together to prevent further loss of property,” said South Hays Assistant Fire Chief Dan Kramer.

The cause of the fire is under investigation.
