What the access labels mean
- Public collecting access verified
- A land agency, official policy or the operator says the public may collect here (rules and fees may apply). We link the evidence.
- Permission required
- The owner or manager allows visits only by arrangement or permit. We link the evidence.
- Access unknown
- The default for USGS records. We have not found an official source saying the public may collect here. Assume private land until you confirm otherwise.
- Not suitable for visits
- The record is a facility, not a collecting locality (for example a processing plant).
- Historical mineral record
- Every site on RockWoof starts as a historical USGS MRDS record. It shows that a mineral was reported, not that you can visit.
