About Mount Whitney
The highest summit in the contiguous US. The 22-mile round trip from Whitney Portal demands a pre-dawn start and an eye on afternoon thunderstorms.
Summit temperature is estimated from the Whitney Portal 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.
