My new garden is set
at over 1500 feet and has winter winds predominantly from the East,
summer winds from the West.

Now that *is* going to be interesting! I imagine that, at that altitude
a good fresh easterly wind is really going to hit home. Very best of
luck. As a not-very-expert-at-anything gardener, my only advice is not
to bite off too much of your acre in one go unless you're more or less
full time and are full of energy. Is this "virgin ground"?
