Half mile east of the airport? East of Telluride is not a good place to be while landing. All the approaches are from the west to Rwy 9, and 27 not always the good choice. Flightaware track ends quite a bit south of the airport. Looks like he took off from Durango, followed the valley north, then headed NW to KTEX. But the FA track indicates he didn't get higher than 12.5 or so, with hills in the area well over 12K. According to the comments in Kathryn's Report, weather was clear, light winds from the west, he was on approach for Rwy 27.
