Farnsworth Bank

Farnsworth Bank rises from deep water off Catalina's rugged backside, its pinnacle tops paved with California's most celebrated marine growth: purple hydrocoral, a slow-growing species so distinctive the site received early protective designation on its account. The color reads even in the blue-green light at 25 m - branching violet thickets patrolled by sheephead, blacksmith clouds, and torpedo rays over the surrounding sand. Being an offshore high spot, the bank collects wanderers: sea lions commuting from the island, yellowtail, mola mola rising to be cleaned in the warm months. Swell and current guard it; boats cancel often, which keeps the hydrocoral unbroken and the dive a privilege.

その瞬間のために: Purple hydrocoral gardens, open-water pelagic chances, Catalina's wild weather side

地形: Volcanic pinnacles rising from deep water, crowned with purple hydrocoral

流れ（カレント）: An open-water bank off Catalina's weather side; trips run only in cooperative seas.

危険生物・リスク: Exposure, surge at depth, current over the pinnacles; cold thermoclines.

保全: The hydrocoral is protected and brittle - buoyancy discipline is the entry fee; anchoring practices are restricted.
