She's a serious climber with experience, skills, and training. Seems unlikely, with her background guiding and leading trips in the Sierra, that a "navigation error" led her off the MR to where she was found.
Looks like she was found in exactly the kind of terrain that she seeks out. "Remote" "aesthetic" climbs with rock? What does that best describe? MR? East buttress? East face? Realizing that it is all relative.
