The 105,000 acre Station Fire is headed east with some movement north towards Acton. As the fire continues its eastward trek it should stay in the Forest and away from populated areas.
According to GeoMac the fire appears to have crossed Highway 2 north and east of Mt Wilson. The USFS Google Earth kml overlay lags GeoMac but both mapping services indicate where the fire is headed on its eastern front.
As it looks the fire is headed towards Crystal Lake and Highway 39.
The image below is from Google Earth using the USFS kml overlay that mimics the GeoMac heat detection software.
NorthTree Fire International has put together this map of the fire perimeter. NorthTree is THE fire mapping service.
