2 SMAS HAD AN NMAC AT AN UNCONTROLLED ARPT.

Narrative

10 MI FROM 3B1; UNICOM WAS MONITORED FOR TFC; BUT FROM PRIOR EXPERIENCE OF NO RESPONSE FROM UNICOM; NO CALL WAS MADE FOR TAS. AT ROUGHLY 1 MI FROM ARPT; NORMAL PATTERN WAS ABOUT TO BE ENTERED BY FLYING OVER FIELD TO OBSERVE WINDSOCK. WHILE XING DOWNWIND COURSE FOR RWY 32; NEAR MISS OCCURRED WITH OTHER ACFT IN TFC PATTERN ON DOWNWIND FOR 32. COURSES WERE 90 DEGS TO EACH OTHER AND OTHER ACFT WAS AT TFC PATTERN ALT (2400 MSL) AND OUR ALT WAS APPROX 2600 MSL DSNDING. NO EVASIVE ACTION WAS REQUIRED ALTHOUGH MISS WAS APPROX 50 FT VERT '0' HORIZONTAL. I FEEL CONTRADICTING FACTORS WERE: 1) NEITHER ACFT; ALTHOUGH RADIO EQUIPPED; WERE ANNOUNCING POS. 2) DUE TO SNOW ON GND AND BRIGHT SKIES AND COLOR OF OTHER ACFT BEING PRIMARILY WHITE; TFC WAS NOT EASY TO SEE. 3) WITH NO ALTIMETER SETTING AND DUE TO MY XCOUNTRY; FLT ALT WAS NOT AS THOUGHT. I FEEL THAT IF ALL ARPTS HAD AWOS OR SOME SORT OF ALTIMETER SETTING ADVISORY THIS INCIDENT COULD HAVE BEEN AVOIDED. ALSO; THERE IS NO SUBSTITUTE FOR RADIO COMS.
