Burgess Shale Fossil Site (Stanley Glacier)

Overview

This is the most approachable way to experience the Burgess Shale in Kootenay. The Stanley Glacier basin exposes fossil‑bearing layers from the Stephen Formation, and Parks Canada’s seasonal guided hike takes you to spots where soft‑bodied animals from the Cambrian Explosion are preserved in astonishing detail. You’ll hike through a fire‑renewed forest, past waterfalls, into a dramatic limestone cirque beneath the glacier.

Why it’s special

The Burgess Shale is a UNESCO World Heritage treasure, roughly 505 million years old and crucial for understanding early animal life. New species continue to turn up in this region—including the headline‑grabbing Cambroraster. Seeing these layers in the field, with an interpreter explaining what you’re looking at, is a different experience than any museum.

The hike at a glance

• Maintained trail: about 10 km return with ~365 m of gain. The first ~4 km are gently graded and well maintained, ending at a great viewpoint into the cirque.
• Beyond the maintained section: expect rougher tread, talus and loose rock; many hikers still explore farther for closer glacier views.
• Terrain sampler: fire‑swept forest with wildflowers, creek crossings, waterfalls and a big‑wall amphitheater under Stanley Glacier.

The guided fossil hike (how it works)

• Season: typically June–September.
• Timing: a full, interpretive day (about 7:30 am–2:30 pm MDT).
• Meeting point: Stanley Glacier trailhead, ~15 km south of Castle Junction on Highway 93S.
• Reservations: required and known to open in January for the coming season—book early.
• Who can go: no pets; children under 5 are not permitted and under 8 are not recommended; English‑only program; a valid national park pass is required.
• Important: this hike does not lead to the protected Marble Canyon quarry site; locations are kept confidential for protection.

What to bring

Parks Canada recommends quick‑drying layers, rain gear, hat and gloves as needed, sturdy hiking boots, trekking poles, a hearty lunch plus snacks, and at least 2 liters of water per person. Sunscreen, sunglasses, insect repellent, a supportive daypack, a small first‑aid kit, hand sanitizer and TP are smart adds.

Rules and etiquette

It’s illegal to collect fossils, rocks or any natural objects in the park—look, learn and leave everything in place. Your park pass isn’t sold at the trailhead, so sort it out in advance.

Best time to visit

June–September offers snow‑free travel and the guided program. Weekdays and early starts make parking and trail traffic easier, especially in peak summer. Morning meet‑ups for the guided hike help you beat the heat and leave time to linger at the cirque afterward.

Nearby add‑ons

Make a short stop at Marble Canyon or the Paint Pots on your drive; both are close to the Stanley Glacier parking area and pair well with this hike.
