The pass is notable for its scenic views, challenging driving conditions, and its role as a transportation route between coastal and inland areas.

Continuous gusts typically refer to a phenomenon in meteorology where there are persistent bursts of wind that last for an extended period of time, rather than short, sporadic gusts. Wind gusts are defined as brief increases in wind speed, often caused by turbulence, changes in atmospheric pressure, or other meteorological conditions. When gusts are described as "continuous," it implies that the wind is consistently gusty rather than being characterized by intermittent bursts that occur sporadically.

Coriolis frequency refers to the frequency at which a particular oscillatory motion occurs due to the Coriolis effect, which arises from the rotation of the Earth. This is particularly significant in geophysical contexts, such as oceanography and meteorology, where the motion of fluids (like air and water) is influenced by the rotation of the Earth.
