## Analysis

THE WX WAS ESTIMATED AT 2,000 TO 2,500 FT OVERCAST WHEN THE FLT DEPARTED GREENVILLE AT 1820. HORSESHOE POND IS 1,500 FT MSL & SURROUNDED BY 2,700 FT MOUNTAINS. AS THE ACFT APPROACHED THE PASS THE POND WAS VISIBLE. HOWEVER A SOUTH WIND PREVAILED & FOG HAD ROLLED OVER THE RIDGE ENVELOPING THE PASS. VISIBILITY WAS REDUCED TO NEAR ZERO WITHIN YARDS OF THE POND. THE PLT WAS UNABLE TO TURN AROUND IN THE PASS & MADE A FORCED LANDING IN THE TREE TOPS.
