I'm still not sure if these boot prints tell us anything significant. First, we don't know when the photos were taken (or by who, for that matter, media photo credit aside*). If they were taken after HC was found and her camp packed up, then I'd guess they are the tracks of SAR folks and/or family who may have retrieved HC's belongings. In that case, not very useful IMO. If they were taken by HC upon her arrival at the site, then the tracks may be hers and someone else's, or they could have already been there from previous visitors. In that case the tracks themselves are not as interesting to me as HC's choice (speculation here) to take initial photos as a part of documenting her experience, or whatever her other motivation may have been. * My best guess is that HC's family/friends took the photos but HC wanted them credited to herself, perhaps not realizing the stringent rules of journalism about such things, explaining why the photos initially credited HC and then were edited to credit "Courtier Family". ** Also please note that in the middle photo, the shadow of the photographer is visible. Looks kinda like something broad, such as an ipad or other tablet, is being used as a camera, but it could just strike me that way because I personally take photos with my ipad. It could also be an actual camera I suppose, but it's not obvious to me.
