About this location
Hibbing was built on the Mesabi Iron Range and sits at the edge of the Hull-Rust-Mahoning mine, once the world's largest open-pit iron mine.[1] The town itself was relocated two miles south between 1919 and 1921 so mining could expand into the original townsite.[1] Iron Range rockhounding centers on the banded iron formation, jasper, hematite, and glacially-deposited agate scattered through mine dumps, road cuts, and gravel pits across St. Louis County. Active and most former mine sites are restricted, though scattered dumps, overlooks, and public road cuts along US-169 and MN-37 offer legal collecting for hand samples.[2] This "area 2" listing likely marks a specific dump or pit near Hibbing distinct from another location in the DB — treat it as representative of the broader Iron Range collecting pattern rather than one confirmed named site.
Always seek permission where required, follow local laws, and practice Leave No Trace. Locations and details are community-submitted and may be inaccurate. Not sure what's legal here? Read our full guide to rockhounding laws by land type.
Found Here
- Iron (banded iron formation, hematite): the Range's defining rock, exposed in road cuts and mine dumps throughout the area.[2]
- Agate, jasper: glacially-transported material found in gravel pits, streambeds, and mine dump gravel across the Iron Range.[2]
- Marcasite, pyrite, goethite: secondary minerals reported from Iron Range mine dumps.
Difficulty
Getting there
Hibbing is in St. Louis County, northeastern Minnesota, along US-169. The Hull-Rust-Mahoning Mine View overlook on the edge of town is a public vantage point over the pit; specific dump access points were not confirmed in this research pass and vary by whether a given mine is active, inactive, or reclaimed.
Collecting here
Road-cut and public-right-of-way collecting is the reliable legal method — pull off safely along US-169 or MN-37 where banded iron formation, jasper, and hematite are exposed. Actual mine dumps require confirming which are open to the public; many active or company-owned sites are restricted.[2] The Minnesota DNR's Lands and Minerals division office in Hibbing is the right first call for current site-specific access.[2]
Know before you go
Active and most former mine sites on the Mesabi Range are restricted or privately/company-owned — confirm access before entering any dump or pit rather than assuming it's open. Minnesota's DNR maintains a recreational geology resource and an underground mine mapping program that's a useful starting point for legitimate access questions.[3] Public road right-of-way collecting (hand samples only, no blasting or digging into the cut face) is the lowest-risk option here.
