Official-source rules, permission pathways, map context and practical next steps—kept separate from the rockhounding atlas.

Maryland State Parks Metal Detecting

These records apply only to verified locations whose written rule and site-specific recreation footprint have been verified. A map pin is a public visitor/reference point, never a permission boundary.

Allowed/restrictedPermit requiredProhibitedRestricted / partialReview

Map meaning: verified coordinate pins identify independently grounded public visitor/access reference points. Query-only records can be resolved on demand as temporary provider search matches; sensitive records use a deliberately broader agency/locality query. Temporary search matches are not stored as verified coordinates. No map mode is a property boundary, detecting zone, archaeological target, or permission boundary.
