Post Break: The range past where any waves are forming, where the water starts to have a significant increase in visibility. There might be some sediment here, but swell energy is diffused and the water is calmer.

Open Water: This zone is far out enough from the shore that the water is at its clearest. It’s deep enough that sediment is not disturbed by the wave energy at the surface. Haze can sit near the surface, so the water is usually clearer the deeper you go.

Field notes

About North Horseshoe Cove

North Horseshoe Cove is the northernmost dive access inside Salt Point State Park, a remote rocky beach that wraps around the back of the cove below high cliff faces. Depths across the cove run between 30 and 50 feet, and a bull-kelp bed, thinned since the 2013 north-coast die-off but still present, forms over the reef through spring and summer. Divers reach the water by carrying gear down a trail from a Highway 1 pullout marked at an opening in a wooden fence above the beach.

The cove was one of the traditional north-coast abalone free-diving destinations before the statewide fishery closure took effect in 2018. Today it is an observation-only site.

The section of the cove where bull kelp anchors on the rocky bottom and grows up to the surface in season is a kelp forest biome. Boulder and cobble across the cove floor and along the base of the cliff faces make the bottom a rocky reef biome.

Parking is at a highway pullout above the beach with no restrooms or other amenities; the nearest facilities sit at Gerstle Cove or Fisk Mill Cove to the south. The Salt Point State Park day-use fee is $8 per vehicle at official park lots. Take of any living, geological, or cultural marine resource is prohibited inside Stewarts Point State Marine Reserve.

Biome

Kelp Forest

The kelp forest biome is giant kelp anchored to rocky bottom and growing up through the water column. The canopy and stipes form a three-dimensional habitat that shelters fish, invertebrates, and the predators that hunt them.

Sub-biome

Rocky Reef

The rocky reef biome is bare rock, boulder, and cobble structure without a kelp canopy above it. The hard relief and its crevices shelter invertebrates and reef fish, and the structure concentrates life that the surrounding sand cannot hold.
