SIERRA VISTA, Ariz. (AP) -- Firefighters have gotten a stronger hold on a wildfire burning near Sierra Vista in southeastern Arizona, allowing some crews to be released from duty.
Fire managers report that the 240-acre Brown Fire in the Huachuca Mountains now is 75 percent contained.
The blaze began April 13 and is burning in brush and timber in steep and rugged terrain, mostly on the Fort Huachuca Army base and in the Coronado National Forest.
No structures currently are threatened.
Crews are spending Saturday doing preventive measures outside the fire area in case a direct attack doesn't work.
The Cochise County Sheriff's Office says Ramsey Canyon Preserve has reopened but only the canyon bottom is accessible.
Authorities say of the 400 personnel assigned, four Hotshot crews have already been released.
