Is there a wind blowing when you hear these noises, as we have an area where I live in Britain called the chasms, depending on which way the wind is blowing when it blows between the cracks in the cliff face it can sound like an injured dog howling, or a ghostly moan.
I did wonder that. When it's windy I do hear it but not always. It's very calm at the moment, no wind and I can hear it. It's not constant, it comes and goes but it is the sort of noise wind would make when blowing through a small gap!! That's really thrown a spanner in the works...
