332:, after which time the location was thought to be exhausted of fossils and excavations ceased. Beecher published three papers describing a trilobite larval form, trilobite limbs and trilobite ventral anatomy from material collected from the site he established. Beecher died unexpectedly in 1904; much material, as well as details of the location, was lost. Research was subsequently limited to study of material collected during the original excavations that had been distributed to various institutions.
339:) and Dan Cooper rediscovered the location in 1984 and from 1985 academic excavations and studies (re)-commenced. At least 4 other fossil bearing horizons exhibiting similar preservation have subsequently been found at the original site. The small quarry at the site is currently closed to public access, being on private land and administered by Yale Peabody Museum as part of ongoing research projects.

Lagerstätten thought to show such preservation were Beecher's Trilobite Bed, the Devonian
