Riffle is a research and reference tool built from locations that have been publicly shared over time through various sources. Listings may be old, incomplete, inaccurate, or no longer valid.

A site shown here may now be closed, privately owned, claimed, restricted, hazardous, seasonally inaccessible, or otherwise unsuitable for entry or collecting. Inclusion on this site does not mean that public access is allowed, that specimen collection is legal, or that conditions are safe.

You are solely responsible for verifying current land ownership, access rights, closures, permit requirements, claim status, collection rules, road conditions, hazards, and all applicable local, state, and federal laws before visiting or collecting at any location.

Collecting may be prohibited or restricted in national parks, state parks, monuments, preserves, wilderness areas, tribal lands, private property, active claims, and other protected or regulated areas. Always contact the relevant land manager, property owner, agency, or authority when needed before entering or collecting.

By continuing, you acknowledge that you use this site at your own risk. Riffle, its owner, contributors, and operators are not responsible or liable for injury, loss, damage, trespass, citation, arrest, confiscation, denied access, property disputes, or any other consequence arising from use of the information provided here.
