If they left the campsite at 1:30 to go to the creek and returned at about 1:45 or so, talked to GGPA, and then began searching for about 20 minutes (keep in mind the times ALL would have been approximations as far as I'm concerned), their search would have ended "about" 2:10. Now, I might be wrong, but I doubt, given the circumstances, that anyone would quibble about ten minutes, one way or the other.
The thing is, there really doesn't really appear to be a discrepancy in the time at all from when they returned from the store, to when they were at the creek and back, to how long they searched, to when they called 911. So many commented about waiting an hour before calling 911, whereas it certainly seems that they actually called after searching for 20 minutes.
I wonder if these are some of the "discrepancies" others refer to, when they aren't discrepancies at all.
