Blue Hour Plunge Pool Below Alberta Waterfall

Cool blue twilight washes over a narrow waterfall cascading into a churning plunge pool in the Alberta wilderness. The water surface boils with white foam where the fall strikes, contrasting against the deep indigo shadows of the surrounding rock faces. Wind whips the mist into a fine spray that rests on the air, blurring the edges of the dark, jagged stones. Bare branches of early winter trees frame the upper left corner, their thin limbs stark against the fading sky. The rock walls rise steeply, their surfaces slick with moisture and dusted with a hint of frost near the crevices. A patch of smooth, dark water reflects the pale blue light just below the impact zone. at the edge is a single ripple expanding outward from the center of the pool.
