September 27, 2013 (San Diego's East County) -- While Altamont Pass operators have been hiding most of their wind turbine mortality with search intervals of 30-90 days, the rest of North American wind farms hide mortality by using search areas that are far too small.  By using only 50 meter search areas for their huge new turbines, the wind facility operators can easily hide over 90% of fatalities caused from turbine blade strikes.
