From the view point before the decent.

Park the bike and look back up.

You have to wonder..

How long until the slither of road on the right of the land slip is gone. They can only build up the top for so long.

Eventually it will collapse from underneath, way down below.

Some slow video bits and some interesting bits.. Especially around the 9 minute mark with a backhoe right up the top of the mountain.

Followed by some pictures.

Above picture. Just after the nasty bend where everything gets messed up in the rain.. You go a little further and the land slips waiting on the left.. Just past here at the next bend to the right.
