Spring, Summer, and Winter Passes

Spring, summer and winter passes
The three - and only known - passes through the Ridge into the Valley. Each has their own peculiarities, hence why the Rudinay Valley was until recently undiscovered. The Spring pass, while open the longest, is thin and treacherous, frequently beset with rockfalls, especially around the central area slashed with deep crevices. The Summer Pass is blocked for all but a few months by the Mettier Glacier, and is so long it would take many months to traverse, therefore but for provident timing, everyone would either think it impassable, or die in the process. The Winter Pass is clearly open, however the deep ravine at its centre can only be traversed when the Skithian glacier fills it, which is when the Pass is at its most frigid, terrifying worst.
