Hi,
About 10:30MDT Sunday, my wife and I flew our 182 from Smiley Creek (U87) to Big Creek (U60) for lunch. We had heard about the 172 which had failed to return to their camp at Johnson Creek. It was discussed at the annual Father's Day Fly-In Breakfast at Smiley Creek.
My wife and I are former CAP members (I was a Utah Search Mission Coordinator and Mission Pilot for years), so we decided to do some informal searching on our own nickel.
After departing Big Creek (marker D on Acme Mapper, see below) at 13:00 MDT, we flew to Johnson Creek (3U2) at 9500' while returning to Smiley Creek, with the intent of doing both a visual search and a listening watch on 121.5 MHz (by unsquelching the SL40).
About 3 mi north of Yellow Pine at 9500' (we could see Yellow Pine township and the Johnson Creek airstrip, marker A on Acme Mapper) we clearly heard three sweeps of an ELT on the unsquelched SL40. Time was 1321 MDT. Did a modest expanding circle search in an attempt to re-aquire the signal, but never heard it clearly again, just could hear the background noise in the receiver being modulated at about the same rate as an ELT sweeps. Didn't have enough fuel to loiter very long.
We relayed the coordinates to Center on 121.5. A helicopter in the area heard the radio traffic about the ELT, and began searching the area. We headed off to Smiley Creek to get our camping stuff, and returned to Salt Lake at 1700 MDT.
Last night, I Googled the news to find the TV link. From reading that account, and the discussion here on backcountryPilots, I see that the aircraft was found at about 1430 MDT, at Crater Peak, which I assume is near marker B on Acme Mapper, and is about 5 mi north east of where we heard the ELT.
