Hannah's body was located and upon initial inspection there is no evidence of foul play. My parents are with her parents now, once we know, and are allowed to share more facts, I can update on what happened.
This is just shocking as she is a very experienced hiker and trail navigator and in WELL above average fitness level. I've backpacked with her oldest brother on several occasions growing up and I know he and her parents instilled good outdoorsmanship in her.
She had her backpack which always has first aid supplies, security supplies, battery pack/phone charger, satellite phone, and her Dad mentioned she always carries a 3 liter water bladder.
We should have more details in the coming days. I really appreciate the texts and words here in this thread, and for those who came out to help search on a 105 degree day. Hannah was an incredible person from an amazing family.
