COURSE SETTER NOTES

Marine park is Brooklyn’s largest park. Environmentally, it consists of 530 acres of grassland and precious salt marsh, protected as a Forever Wild Preserve.

Topographically, it is a flat landfill (1930s-1960s) with numerous pseudokarst depressions.

There are plenty of trails.

The area is covered - in more-less equals proportions - by impossible-to-travers overgrown patches, tall (up to 10 feet) thick salt marsh reed, aspen groves of different thickness, and semi-open or open spots.

The park was mapped in early 2023, minor updates were made in 2024 and 2026.

The map was drawn using ISSprOM 2019 orienteering map symbols.
