I'm thinking more about what gear I carry for what temperature I expect, as I often have the choice of heavy and safe, or light and risky. This goes for boots, sleeping bag, tent etc. I took my heavy sleeping bag the last few days, and stayed warm, but I'm wondering what the temperature actually was so I can make these decisions easier in the future.
I know there's a general rule along the lines of minus a degree for every hundred metres altitude, is this accurate ?
If it was forecast -4 in Maydena (300 masl) the last few nights, what was likely the temperature camping at Mt Field (1200 masl) ?
All I know is it was *&%$#! cold out.
