I was sceptical when I first read your message because ot the TDH being so sensitive to wind.....really only a geologist or seismologist could figure it out, however I do agree very much with which youhave observed.....There are some very interesting things going on there...After all we must consider that Mt Hood broke the all time snowfall record for the WORLD last year! And I have a cam site linked to what is happening no vis a vis weather......A very important location to watch...You were certaily correct in your observation!
