Narrative:

My student and I were returning from our cross country flight. We had radar flight following with salt lake city center. They handed us off to salt lake city approach who then handed us off to pvu tower. I reported to pvu tower we were 9.0 NM southwest of the airport and we were inbound for landing. Our altitude was 6;500 MSL; consistent with local arrival procedures. Pvu tower had us proceed to the creek and report the creek; and issued the following traffic advisory: 'traffic 1 o'clock and 4 miles; northbound; altitude 6;000; type unknown' and that they weren't talking to this traffic. I told my student to remain at 6;500 to allow that traffic to pass below us. About 3-4 miles later; pvu tower said that traffic was now '12 o'clock less than a mile; altitude 6;300'. The airplane blended in well with the terrain and we never saw it until it was at our same altitude 11 o'clock and about 500 feet away laterally. I reported that traffic in sight. Tower asked us what type of aircraft it was; and I told them it was a piper; possibly an arrow or saratoga; and that they were departing toward ffu. The airplane was close enough that I could almost make out the tail number; but I was unable to due to the fact it was only a hazard for a short moment of time. We informed tower that it got within 500 feet of us. The aircraft never did show up on their screen; and it would have if the airplane contacted salt lake city approach and received a transponder code. My student and I were actively looking for this traffic from the moment of the first traffic advisory from pvu tower.
