About Half Dome
Yosemite's granite icon. The cable route is permit-only and closes the moment thunderstorms threaten — wet granite is unforgiving.
Summit temperature is estimated from the Yosemite Valley forecast using the −6.5°C/1,000 m lapse rate. Expect much stronger wind and lower visibility on the tops, and treat the freezing level as a guide rather than a measurement.
