Sea Arch Coastal Formation - Dramatic Erosion Landmark on Sandy Beach #3539303 (License: Personal Use)

This striking coastal feature showcases a large natural arch carved through dark, stratified sandstone cliffs, its underside smoothed by centuries of tidal erosion. Moss-covered outcrops crown the formation, contrasting with the pale sand beach below and the muted tones of an overcast sky. The scene evokes both geological power and serene isolation, typical of remote Pacific Northwest or Cornish coastlines.
