The West's 2012 wildfire season exploded in earnest last month with a wind-whipped blaze that killed three people in rugged alpine canyon country near Denver. At its peak, it took a 700-strong federal firefighting team a week of labor, day and night, to tame the blaze _ and other states throughout the West took notice.Fire experts say this year's drought, low snowpack and record-high temperatures in much of the West portend a dangerous installment of what has become year-round wildfire threat.
