Mount Stephen Trilobite Beds

by phone

Due to the unseasonably warm weather we've lengthened our season by offering hikes beginning June 11th.

If you are new to the Burgess Shale and wish to see abundant and obvious Cambrian fossils, this is the hike to do. The site is strewn with rock slabs containing appendages of the Cambrian predator Anomalocaris canadensis; trilobites Ogygopsis klotzi, Olenoides serratus and Elrathina cordillerae as well as brachiopods and sponges.

The Mount Stephen Fossil Beds were discovered in 1886, after railway workers reported finding what they called "stone bugs" in the talus on the slopes of Mount Stephen. Learn about the environment in which these creatures lived and perished and why many of the species that are found here do not occur at the Walcott Quarry site. This is a great hike for kids who will enjoy studying the rocks to find relatively large, easily recognizable fossils.

Please note: Although the trail to the Mt Stephen fossil beds isn't long, it is nevertheless classified as a STRENUOUS hike because the route is quite steep. The elevation gain is almost the same as for the Walcott Quarry hike, but the workout is intense as the climb is over a much shorter distance.

Are You Ready?

Every participant in the Guided Hikes must be sure to read and understand the guided hike waiver, and then complete and sign the waiver form and hand it to the guide on the morning of the hike. Please read our Reservation and Refund policy before you make a reservation.

The Field town-site is situated at 1,280 meters (4,200 feet) above sea level. Hikers will be climbing more than 760 meters (2,500 feet) to visit either of the destinations: Walcott Quarry and Mt. Stephen Fossil Beds. At this elevation there is considerably less oxygen than at sea level, and the fatigue of climbing and descending will be be noticeable if you are used to training at lower elevations. Although our guides pause for breaks along the way, you will not enjoy the trip unless you are fit and acclimatized to the altitude.

The trails are well-maintained by Parks Canada. Nevertheless, they are steep and may become slippery in wet weather. Portions of the trail may be snow-covered until mid-July. Hikers may find the descent is hard on the knees or that uneven surfaces are a test of ankle stability. In the event of injury, there is no easy way out and one must be prepared to hike out with minimal assistance. You should not undertake these hikes if you have any respiratory, circulatory or joint problems. If unsure, check with your physician. Please! Carefully read the advice and reservation and refund policy.

Protection and Security of Fossils

No collecting of fossils is permitted and no disturbance or damage to any natural object is allowed. The hikes are not research expeditions and consequently no one may break rocks at any time or location on the guided hike. These fossil sites are located restricted areas within The Canadian Rocky Mountain Parks UNESCO World Heritage Site and are protected by the National Parks Act. Entry is permitted only to groups led by guides who are licensed to enter these protected sites. The fossil sites are monitored by motion detectors and cameras. Burgess Shale Geoscience Foundation guides carry radios and they will immediately contact the Park Warden Dispatch to report any suspicious activities.
