Yoho National Park, Canada – Parks Canada has suspended independent hiking permits to Mount Stephen in Yoho National Park (UNESCO World Heritage Site) following repeated incidents of fossil theft. Fossil theft has become a serious concern in the region.
The restrictions were announced on July 17, 2025, after repeated fossil thefts from the area. This included two American hikers who stole fossils last year from the Burgess Shale UNESCO World Heritage site. The Burgess Shale is renown for its deposits of well-preserved “stone bugs.” The Americans were charged and convicted. Each faced fines of $4,750 and thankfully the stolen fossils were returned. Fossil theft penalties are crucial to deterring future incidents.
Parks Canada and the GeoScience Burgess Shale Foundation will still be offering guided hikes of the trilobite bed. However, visitors will no longer be permitted due to the inability to summit the mountain. This change was partly influenced by concerns over theft of fossils impacting the park’s conservation efforts.
The Burgess Shale, a 508-million-year-old fossil bed, is one of the world’s most significant paleontological sites, offering critical insights into the Cambrian explosion, a period of rapid evolutionary development. Fossils from this site, including trilobites and other ancient marine life, are exceptionally rare and scientifically valuable. Unauthorized removal disrupts research and diminishes the site’s integrity, making fossil theft a grave issue. Parks Canada has emphasized that protecting this heritage is a priority, as the fossils are irreplaceable. Guided hikes, led by experts, ensure proper oversight and education about the site’s importance.
The decision to restrict access has sparked mixed reactions. Some visitors are disappointed, as independent hiking allowed for a more personal experience. However, conservationists support the move, arguing that stricter measures are necessary to preserve the site. Parks Canada is also increasing patrols and installing signage to deter fossil theft incidents. Violators face hefty fines, potential jail time, and confiscation of stolen materials. The agency encourages the public to report suspicious activity to help safeguard Yoho’s natural and cultural treasures for future generations.
