FB: since the weather forecasts for both those locations are estimates and not actual measurements, I don't think records are kept at all. It would be really helpful if a weather station were installed at the summit hut, and I even tried to discuss it with a Sequoia N.P. official some years back. The response I got was that it would just be that much more "junk" in the backcountry. I have the feeling I may have been talking to the same person who told me he thought people couldn't have a true wilderness experience if they carried a satellite tracking/locator device in the backcountry.
