Motto of the Baltimore Grotto

“Baltimore Grotto” is not an individual author but the name of a local caving organization: the Baltimore Grotto, a chapter of the National Speleological Society (NSS). In caving, “grotto” commonly refers to an NSS-affiliated local group rather than a physical cave. Attributions to “Baltimore Grotto” in quotation contexts typically indicate that a phrase, slogan, newsletter line, or club saying circulated within the group, not that it was written by a single identifiable person. Because such material is often shared informally among members, specific authorship can be difficult to verify without a dated publication or credited source.
