About the heat... a Heat Island isn't something normally found in Kaslo or Area D. It is more an urban phenomenon: " a dome of elevated temperatures over an urban area caused by the heat absorbed by structure and pavement". (long iive our wilderness and small amounts of pavement, if that's the case).
And what causes a Heat Island to happen?...why, "Insolation". Not the pink fluffy stuff in your attic....but "incoming solar radiation: or , solar heating: (ie, "sunshine"). That part is nice, in reasonable doses..
