One of the most beautiful locations on planet Earth, set aside as a nature preserve in 1890. Yosmite provides rewarding shoreleave with El Capitan's challenging mountain range for Captain Kirk. So he beams down and tries to make an ascent. In 2267 Kirk was joined by his "USS Enterprise NCC 1701" shipmates Spock and Dr. McCoy for a camping expedition, fireside Sing-A-Long and free rock climbing.
Captain Kirk is climbing the mountain but why is he climbing the mountain?
