 Expansive view looking north-northwest from the southern end of the Sestroretsk coastline towards the Sestroretsk Resort (Kurort) and, further in the distance, the settlement of Solnechnoe (Sunny). The coastline curves gently inward. This specific geography near Sestroretsk causes the eastward littoral drift (sand movement) to weaken, resulting in a very wide, accretional beach (up to 140 meters wide) known for its fine sand and extensive dunes. The foreground shows a sandy spit or sandbar created by the outflow of water. The shallow water here creates the wide, calm pools seen in the foreground, which are popular with birds.

 Intricate patterns in the sand that are wave-formed ripples (also known as oscillation ripples), which provide a frozen snapshot of the water s movement just before the tide or water level receded. They are formed by the back-and-forth oscillatory motion of water particles at the bottom of shallow waves. As a wave passes, water moves sand grains forward and then backward, piling them into these neat, parallel ridges. The crests (ridges) of the ripples run parallel to the shoreline, which is typical for wave-formed ripples as they align perpendicular to the direction of wave propagation. The preservation of such sharp ripple crests indicates the water receded gently, likely during a calm period after the windier conditions that initially formed them.
