AnomalyVery low steady, even vibration just short of suggesting a synpathetic vibration in the wood floor. Very very soft. Going outside can't hear it. Have noticed this at any time of year. in winter access is 4 miles to ski in, there are then no other inhabited structures within 1-2 miles. It is truly empty country.
