While I did technically make it to the north shore, I didn't go very far. I asked one of the people working on the anti-predator fence how far to the road and he said a couple more miles. I'm not sure how accurate my end point on this map is.
The chasm to be crossed.
Here is my bike in billy goat mode. In one direction I went over the upper path (carrying and pushing the bike, riding is impossible) and on the way back, I took the "short" route across the gap. This required moving the bike, then moving me, then moving the bike, etc.
