Observations from the trail.

The Whiteout: Navigating Without a Horizon

When overcast cloud blends into unbroken snowpack, depth perception vanishes completely. The human brain loses reference points and leans heavily on compass bearings.

In a true arctic whiteout, you cannot tell whether the next step is flat snow or a fifteen-foot cornice drop. You navigate by tying a trailing marker line behind your sledge, watching your compass needle every twenty paces, and listening to the tactile crunch of hard-packed wind-slab under your ski edges.
