description Blowing Rocks Preserve Overview
Blowing Rocks Preserve is a protected coastal site maintained by The Nature Conservancy on Jupiter Island in Florida. Its shoreline exposes Anastasia limestone, a sedimentary rock composed largely of shell fragments; during rough seas and favorable tides, waves forced through gaps in the rock can send columns of water into the air. The preserve also protects native coastal habitats and is visited for nature observation, photography, and study of Florida's shoreline geology.
