Please keep an eye out for a Grey Wahoo Elemnt Bolt.  Although the GPS was sync to my phone, I couldn't upload it cause the GPS never properly stopped.  I tried looking at the plotted map of where it was last synced, but it is hard to determined exactly with all the swiggled lines and it being my second lap, some of the lines crosses each other making it even harder.   
I realized it was missing right after I completed Death Valley Loop. Also based on the synced summary, the distance was 25miles exact, which would have meant it was dropped around the end of Death Valley area.
