Every year the Caltech Y, a Caltech associated community involvement organization, runs a week-long hike in the Sierras for incoming students just before orientation and rotation. Normally at this time of the year, I am involved in International Student Orientation, but this year I decided to lead the hike instead!
About 25 people total were involved, split into three groups according to degree of ambition to achieve altitude sickness. I was assigned the 'beginner' level group, which was pleasantly cruisy, walking 3-5 miles (5-8km) per day. Normally arriving at camp by midday, we had plenty of time to explore, climb, look for bears, filter water, and shiver.

For a change I used a GoPro instead of my regular camera. It is much more wide-angle and more versatile, though nearly useless for night-time photography.
After a week all three groups met at Lodgepole campground and compared notes and blisters. Noone died! Success all around. I had only previously hiked on the eastern escarpment, so it was nice to explore the interior of the range.
