Lighthouse Beam Sweeping Fog at Twilight

Cobalt twilight deepens over an alpine saddle in Indiana as the first stars pierce the darkening sky. A long exposure shows the lighthouse beam as a continuous arc of white light slicing through thick fog that blankets the valley below. City lights begin to glow in the distance, forming a scattered cluster of amber dots against the blue horizon. The wet air condenses on the foreground rocks, creating a slick, reflective surface that mirrors the sweeping beam. Raindrops rest on the lens edge, slightly blurring the lower frame while the light trail remains sharp and distinct against the misty backdrop. The beam cuts a precise geometric path through the soft, gray vapor.
