Pebbles dominate the upper beach, grading to coarse sand near the waterline where the river's current sorts sediment. You watch the freshwater flow cut channels through the shore, creating temporary lagoons that trap kelp and small fish. The stream runs tea-colored from upstream peat bogs, staining the surf zone amber before the Atlantic dilutes it to transparency.

Sunset here backlights the river's outflow, turning spray into golden mist. The western sky often shows layered clouds in shades of pewter and salmon, their reflections rippling across the delta's shallow pools. Seabirds congregate at the confluence—gulls, terns, and occasional cormorants—exploiting the mixing zone where nutrients concentrate. You'll see their footprints crisscrossing the sand, a temporary record erased by the next tide.
The beach curves gently southward, disappearing into coastal haze. No structures break the sightline, no paths suggest regular visitation. You're alone with the wind's constant commentary and the overlapping rhythms of river and ocean. The isolation feels complete but not hostile—indifferent, perhaps, which seems appropriate. Pack out everything you bring; there are no second chances here, no supply caches or emergency shelters.
