Karst
Privacy-first map

Roughly where.
Never exactly where.

Most of these caves are gated, on private or conservancy land, and home to endangered bats and blind cavefish. So the map shows general areas — a town, a county, a coarse cell — and never the door. The precise entrance stays a real-world, trust-based handoff.

How a conservation map works

Obscured wild caves

Sensitive caves snap to a coarse ~3-mile grid before anything is stored — the true point never touches the database. A circle over real coordinates would be fake privacy; this isn't.

Real pins for public caves

Commercial show caves and state-park caverns are already advertised, so those get exact pins and links — no reason to hide what's on a billboard.

Only caves in view

Search by name or county and see just the caves in your current viewport — tap one to fly straight to it.

Karst regions & lands

Conservancy lands (Hoosier National Forest, IKC preserves) and how to seek access in each — the map is for orientation and planning, not navigating to a hole in the ground.

Built to protect what's underground

The cave world runs on trust: publish an exact entrance and you invite trespassing, vandalism, and harm to fragile ecosystems. So Karst deliberately blurs sensitive locations — roughly where, never exactly where. Members of a verified grotto can unlock member-only locations, earned through the community, not by showing up at a gate you found online.
