List of caves of Maryland
The subject of this article and a reference book of the same name, ''Caves of Maryland'' was first released by the Maryland Geological Survey (MGS) in 1950. Information about Maryland caves was first gathered into a series of reports by Martin Muma in the mid-1940s, working under the MGS. After the release of these articles in 1946, a more comprehensive study was begun by William Davies, whose years of fieldwork led to the compilation of the premiere edition of ''Caves of Maryland'' in 1950.〔Maryland Geological Survey's ''Caves of Maryland'', 1971〕 Since its publication, this reference work has remained the principal source for information about Maryland caves, and has served as an outline for the work to follow.
==Introduction==
Following the release of the first edition of ''Caves of Maryland'' in 1950, several other attempts by various parties and interested groups have been made at expanding available information concerning Maryland's subterrain. In the late 1960s the MGS sponsored another statewide survey, undertaken by Richard Franz and Dennis Slifer, and a second, expanded edition of ''Caves of Maryland'' was released in 1971. It was not until the inception of this second project that areas west of Washington County were even thoroughly canvassed; even after the conclusion of the Franz/Slifer survey, it was speculated that even more, undiscovered caves could still remain in more remote portions of the western counties, prompting the need for an additional version, but since that time there have been no additional state sponsored reports or surveys released to the public.
In Maryland, a cave is defined as any subterranean cavity large enough for a human to enter.〔(Virginia Region of the NSS ) Maryland Cave Law〕 This definition has led the authors to include several shelter caves, fissures, and mines that in states with larger, more complex cave systems, might otherwise go unlisted.
