I got some clarification of where the skull and scapula were found (and now a bunch more bones). Initially I was told that it was found upstream on land from my dogs interest. They actually were found directly in between the two strainers behind the large bushes my dogs kept going up onto the bank and behind (again, my total bad for not following and instead being locked into the river mindset), and then back from there. Bear scat all around, so conclusions are that bear found the hang up spot of body and pulled it to land. It probably hid it during consumption because family and LE had been on that side many times in between the 2 months we awaited the water lowering to acceptable levels.
Lessons learned for me: -trust your dog..follow your dog even if outside the perview of my expectations
-in drowning of rivers, check banks every time you search because predation is always possible
-SAR is always a learning experience and new things can and will happen even to the most experienced (I was in contact
with handlers 20+ yrs of experience and this was a surprise for them due to the full spectrum of flood to finish.
