Into Hithlum

[Galin]

But does this not help raise the question of why Tuor used the Gate instead of the pass -- a pass of some kind that others appear to have used, or sought? Arguably one could use this pass, eventually climb into the ravine where it was less steep, and climb out again (now generally moving South) -- if dangerous, one would still be in the ravine as Tuor ended up in any case.

If the pass was well watched in Tuor's time, that could explain things, but at the moment I don't recall that being mentioned.
