I'm quite familiar with this area I live & work within a short drive to were car was found. I've traveled the ATV trail I think his car was found on quite a bit. It is a odd place to park your car for a hike that might have lasted longer than a day. Although ATV trails were closed at this time people still use them. I was on trials around this time just not that one. At the time there still would have been a snow pack on ground mostly in shaded areas. He might have been interested in the are because a tornado went through and cleared a path there about 10+ yrs ago. Trees are grown about 10' high but look tiny compared to trees on outside of scar. So I'm assuming from reading article he parked on or around ATV trail that takes you from blue spruce to shadow lake. So if that is the case that begs to question why he would have headed south back across hwy 64 to blue spruce. Spruce is a national forest road that doubles as an ATV trail. There are many forest roads that branch off that are mostly dead ends. The trees are real close together & would be at places hard to walk through. Even in spring when leaves and other foliage are not present.
