Containment was up to 90 percent at the end of Monday on a 14-acre fire near Rowena.  On Monday firefighters focused on mopping up interior hot spots and extinguishing visible smokes.  Crews also worked to grid within the fire area, exposing the trapped heat, and then dousing with water.  Firefighters from the Oregon Department of Forestry’s The Dalles Unit will complete the remaining mop-up work Tuesday then place the fire in patrol status.  The fire was initially reported Sunday afternoon burning in grass, scrub oak and ponderosa pine near Rowena.  Sandy soils and light flashy fuel conditions in the fire area allowed it to burn through quickly and trap minimal heat.  Air resources were critical in slowing the spread of the fire in difficult terrain.  The fire was human caused and under investigation.
