What rocks, minerals, fossils or collecting interests are associated with it?
The record lists St. Peter Sandstone, canyons and glacial/river geology. This description is tied to this atlas entry and should be read together with the access status below.
Who manages the place or provides the evidence context?
The recorded manager or context is Illinois State Park.
What evidence supports this status?
The record was last reviewed on 2026-08-20. Evidence and management context: Illinois State Park. Included for complete Illinois search/research coverage without weakening present owner, manager, permit, protection, access, safety, fossil-class, season, retention or mineral-right requirements.
How precise is the map marker?
The map uses named-place or LaSalle context for navigation. Resolve the exact site and current field authority before relying on the location for collecting decisions.
Recorded map precision: county-level context. Geographic context is not a collection-right or legal-boundary determination.
Checks specific to this location
- Check this protected area’s current removal and access restrictions; a recreation destination may be viewing-only.
- Treat this record as research or viewing context unless the current authority explicitly confirms the proposed collecting activity.
- Verify the exact destination, the land manager’s latest rules and safe travel conditions before leaving.
When was this information last checked?
The recorded review date is August 20, 2026. Treat that date as the evidence snapshot used for this classification. Conditions can change after review, so field decisions should use the newest posted rules and manager information.
Is a map pin the same as collecting permission?
No. A map pin answers a navigation or geographic-context question. The status and evidence answer the permission question. Exact coordinates, public destination addresses and approximate county or regional context are deliberately kept separate so geographic precision is not confused with legal authority.
Starved Rock: sandstone canyons are viewing resources
Starved Rock State Park is a protected landscape where erosion, unstable rock and steep canyon paths can be dangerous. View and photograph the sandstone geology from open trails; do not assume public recreation allows hammering, digging or collecting stone and fossils.
Follow current trail closures
Ice, water and loose sandstone make some routes unsafe throughout the year. The park record and state manager notices should control visit decisions rather than a geological formation pin.
