In the middle of the pic below you can see a small house and to its left the outline of a tunnel portal:

Wide angle of Three Chop Ridge

The homestead is sitting on a platform. This platform is strong enough to be stood upon so that we can reach the top of the ridge. The platform was the last piece to be installed of theThree Chop Ridge frame. The pics below show the construction in progress.
