Mount Olympus (2917 m) is the highest peak in Greece, and of course a mythical place.

Mt. Shasta (14,162') is this northern-most 14er in California. The standard route climbs from Bunny Flats at 6,880' to the Sierra Club cabin at Horse Camp (7,900'), and from there up Avalanche Gulch to the summit. The current and previous FKTs were timed from Horse Camp.
