Walcott locates the Burgess Shale beds
Charles Doolittle Walcott, Secretary of the Smithsonian Institution and a palaeontologist of the Cambrian, located the fossiliferous beds on the ridge between Wapta Mountain and Mount Field during fieldwork in the Canadian Rockies. The often-repeated story of a horse stumbling on a fallen slab is probably embroidered, and published accounts differ over whether the productive beds were found in 1909 or traced to their source in 1910. What is not in doubt is what followed: Walcott returned repeatedly, opened what is now called the Walcott Quarry, and shipped tens of thousands of specimens to Washington, where he described them over the following two decades — assigning most of them, on the assumption that the animal groups of the world were already known, to living phyla.
Historical — it happened, and the record is settled.

Evidence
Partly verified — Core facts are sourced; some optional detail is deliberately absent. This is the standing of the weakest source, not an average.
Wonderful Life: The Burgess Shale and the Nature of History
Supports the narrative of Walcott's discovery and classification, the Whittington–Briggs–Conway Morris re-description, and the reassembly of Anomalocaris from three separately named fossils. Gould's own thesis about disparity and contingency is a contested interpretation and is not asserted as fact in this pack. V55 verification basis: this session had no network access to any source — WebFetch was egress-blocked and the WebSearch budget was exhausted — so the cited work was not retrieved and its pagination was not re-checked.

Burgess Shale — site documentation and interpretation
Supports the location of the Walcott Quarry on Fossil Ridge in Yoho National Park, the quarrying history and the site's protected status. V55 verification basis: this session had no network access to any source — WebFetch was egress-blocked and the WebSearch budget was exhausted — so the cited work was not retrieved and its pagination was not re-checked. Neither the Parks Canada nor the Royal Ontario Museum documentation was opened, so this record stands on the institutions being the recognised custodians rather than on a retrieved page.
