The Stanley Glacier locality in British Columbia is an exposure of the "thin" Stephen formation exhibiting soft-tissue preservation.[1] Fossils were discovered by a hiker who reported the find to Parks Canada; this brought the site to the attention of scientists who were able to study the site and describe the new biota.[2] The discovery of Burgess Shale-type preservation in the thin Stephen was unexpected, given the absence of the Cathedral escarpment in the area.[1] Several new species, including Stanleycaris, have already been found in exploratory excavations at the site.[1]
