I'm having a grand time following along (via Google's maps and the photos people post on the trail markers) on Xena's hike. Today, after a pretty steep set of switchbacks, the trail crests and will give her this view of Echo Peak.
She had some cell reception after she got out of Little Yosemite Valley, so I know she ditched her pack and took a short detour to the top of Half Dome. She is somewhat off the pace to get all the way to Mt. Whitney. Today, if she can get through Cathedral Pass (9700 ft) and spend the night at Cathedral Lakes (always sleep lower than you climbed) she'll be somewhat back on schedule.
I'm assuming of course, that the schedule is the important part. Perhaps it isn't, since she is clearly doing some sightseeing along the way. If she ends up calling me from Onion Valley 18 days from now to collect her, that would be just fine. Sometimes its better to enjoy the journey than to be dead set on reaching a specific goal.
