Narrative:

After departing the Y14 traffic pattern sebound en route to the local practice area, my student pointed out another aircraft (piper tri-pacer) at our 2 O'clock position at our altitude. I took control from the student and initiated an immediate descent. I hadn't spotted the traffic prior to the student, and had to lean forward to view around the windshield post. The tri-pacer passed behind and slightly above following our descent. No radio calls were heard from a tri-pacer on the CTAF. The tri-pacer was white and the local terrain was snow covered making earlier recognition difficult. The WX was clear and visibility unrestr.
