APCHING HII VFR FOR LNDG; A C172 LOW TIME PLT ENTERS INCORRECT TFC PATTERN FOR CALM WIND RWY.

Narrative

I AM A PVT PLT IN TRAINING. I WAS ON A SOLO XCOUNTRY FROM PRESCOTT DIRECT TO HII. WHILE ENRTE TO HII; I GOT THE ATIS AND MADE A RADIO CALL ON THE CTAF; STATING MY INTENTIONS. I WAS AWARE TO USE RWY 32 (CALM WIND RWY) AND TO ENTER ON A L 45 DEG FOR THE DOWNWIND LEG. WHEN I ARRIVED AT HII; THERE WAS NO PATTERN ACTIVITY OCCURRING. I ENTERED ON WHAT I PRESUMED TO BE A L 45 DEG FOR RWY 32. HOWEVER; IT TURNED OUT TO BE A L 45 DEG FOR RWY 14. REALIZING MY MISTAKE; I TURNED XWIND AND ENTERED THE L DOWNWIND FOR RWY 32; MAKING SURE AT ALL TIMES THAT THERE WAS NO TFC IN THE AREA. AFTER CORRECTING MY MISTAKE; I DID A NORMAL TFC PATTERN AND LANDED SAFELY ON RWY 32. BECAUSE THERE WAS NO TFC IN THE AREA; I POSED NO DANGER TO THE SURROUNDING AREA. HOWEVER; I WAS CLOSE TO THE MOUNTAIN TOPS BORDERING THE L DOWNWIND OF RWY 14; WHICH I BELIEVE COULD HAVE BEEN A SAFETY CONCERN. BETTER PREPARATION AND SITUATIONAL AWARENESS COULD HAVE PREVENTED THIS INCIDENT FROM OCCURRING. EVEN THOUGH NO LIVES OR PROPERTY WERE THREATENED; I WAS QUITE LUCKY TO HAVE ESCAPED WHAT COULD HAVE RESULTED IN AN ACCIDENT OR COLLISION. I HOPE THAT THIS RPT WILL BE A GOOD LESSON FOR PLTS IN THE FUTURE; TO BE WELL PREPARED FOR THE FLT; NO MATTER HOW MANY TIMES IT HAS BEEN DONE; AND TO ALWAYS BE ON ALERT.
