Nemo found us

Mahkulu Kaya - (Big Boss Tunnel) with about 1000+ lbs of snow at the apex, and the beams were starting to take strain, but they stayed put... very glad about that. We will be adding support pillars under each arch as soon as possible. Did not sleep at all this night..!! We also seem to have a draft problem that needs fixing... :)
Those drums are frozen solid and seem to be quite happy, but we'll see in Spring when it all thaws out.
