Brainerd

Brainerd is the seat of Crow Wing County in central Minnesota — well inland, nowhere near the actual shore of Lake Superior. That matters because this entry's specimen, Lake Superior agate, is named for its geologic origin, not its geography: glaciers carried agate from the Lake Superior basin across much of Minnesota and deposited it in gravel outwash statewide, including in glacial gravel pits around Brainerd.[1] So "Lake Superior agate near Brainerd" is a real and common claim, just not one that means you're anywhere near the lake itself. Access runs through private gravel pit operators rather than public land — some pits allow collecting by permission, which means asking before digging.[1] A related, rarer specialty — binghamite, a fibrous variant of Lake Superior agate — is documented specifically at the nearby Cuyuna Iron Range, not at Brainerd itself.

Brainerd sits in Crow Wing County, central Minnesota. Glacial gravel pits in the surrounding counties (Morrison, Crow Wing, Mille Lacs) are the general source area — no specific pit name or address was confirmed as currently open to the public in this pass.

UNVERIFIED, general guidance: some gravel pits in the region allow agate collecting by permission — contact the pit operator directly before showing up.[1] The general Minnesota agate season is described as May through October, tied to the state's harsh winters, though Brainerd itself is inland and not subject to the Lake Superior North Shore's specific weather pattern.

Access is presumptively permission-required: these are described as private gravel pits, not public rockhounding sites, and "some" allowing collecting implies others don't.[1] No specific pit was confirmed as currently active or open. Don't confuse Brainerd's inland location with the actual Lake Superior shoreline — if you're looking for the lake itself, you want Minnesota's North Shore, several hours northeast.
