Thirty years ago I took my fiancée canoeing down the Green River in Utah for a week in July. It was on that trip that I learned that after camping in sand for several days, certain activities are extremely problematic.
When we went to bed, it was too hot to sleep, and when we woke up it was too cold to sleep. Because of the lack of humidity, temperatures would plummet over night. This is due to :
- lack of greenhouse gas H2O
- lack of vegetation to release heat
- lack of latent heat of condensation
- cold air sinking to the river bottom
