Yosemite National Park , California ( CNN ) -- Susan Loesch and Curtis Evans just started settling into their second home in California 's Sierra foothills a few months ago . Now , they 're worried it could go up in smoke as a massive wildfire spreads . `` This is kind of a little paradise up here for us . ... To think this would all be gone would be devastating , '' Evans told CNN Sunday . Cradling their chihuahua , Cuervo , they prepared to leave the area on Sunday as more than 2,800 crew members struggled to corral the sprawling Rim Fire , which had devoured nearly 134,000 acres . `` It 's scary , '' Loesch said . `` You worry about the firefighters being on the line . ... It 's overwhelming . '' The wildfire , which remained 7 % contained , was spreading primarily to the northeast and east and threatened to grow amid extremely dry conditions and hot weather . After days of battling the blaze , things were looking up on Sunday , said Vickie Wright , a spokeswoman for the U.S. Forest Service . `` We 're a long way from complete , '' she said , `` but at least our boots on the ground are getting a better handle on it . '' A top priority is stopping the fire from spreading further in Yosemite National Park . Yosemite fire : Blaze spreads to national park . `` The park is a national treasure , '' she said , `` so no matter what it takes , we 're going to do everything in our power to protect that park . '' While the Rim Fire had consumed 12,000 acres in the northwest section of the park by Saturday , so far it has had little or no direct impact on Yosemite Valley , a popular spot for tourists and home to many of the famous cliffs and waterfalls in the park . About 4,500 structures , many of them vacation homes , were under threat , according to InciWeb , a federal website that collects information from agencies such as the U.S. Forest Service and Bureau of Land Management . Several helicopters and air tankers were aiding firefighting efforts . The inferno threatened the Yosemite gateway communities of Groveland and Pine Mountain Lake just outside the Stanislaus National Forest . The Tuolumne County Sheriff 's Office , meanwhile , issued evacuation advisories for the town of Tuolumne and nearby Ponderosa Hill , according to InciWeb . It was not clear how many residents were covered by the evacuation advisory . Authorities say the Rim Fire started on August 17 . The cause is under investigation . Yosemite spokesman Scott Gediman told CNN on Saturday that the Rim Fire 's impact was restricted to a park entrance closure at Highway 120 West and a backcountry section used by hikers . The park typically has 15,000 visitors on a busy summer weekend . August sees an influx of visitors from other countries , a few of whom have called to check on conditions . Still , there 's little indication so far it 's keeping many people away . Ranger programs went on as normal Saturday and campgrounds were full . `` If somebody cancels , there are 10 people that will take their spot , '' said Gediman . Yosemite , with hundreds of campground sites and lodging units , had nearly 4 million visitors last year , according to the National Park Service . What you need to know about wildfires .
