| Jan 11, 2017 at 23:27 | comment | added | Brian Lacy | @cybernard The problematic assumption is that the edge of the ravine has at least two points which extend beyond the edge of the island. The OP does not explicitly exclude this possibility, but it's a pretty drastic assumption. | |

| Jan 11, 2017 at 20:16 | comment | added | cybernard | @KevinWells As demonstrated by the pink area only a tiny fraction of the circumference has to be accessible. The rest can be air space,ravine, or whatever. In fact as long as you can get from point 1 to 2 it still works. As long as you can pull the rope tight across the ravine, it works. No part of the persons question says this is not ok. | |
| Jan 11, 2017 at 19:29 | comment | added | Kevin | This answer seems to assume that the island is in the middle of a hole, not in the middle of a ravine (think grand canyon). If you can walk around the entire hole then the problem is much simpler, but that isn't what is described in the question | |
