Speleological Surveys are Internal Organizations made up of individuals and organizations engaged in gathering speleological data in a general geographical area. The primary purpose of a survey is to maintain a centralized file for the cave area and to prevent duplication of work among members. Copies of maps and information compiled by the surveys should be sent to the National Cave Files Committee . A complete list of all surveys, past and present is presented in Table 5C . Special Sections, or Sections, are Internal Organizations made up of individuals with a specific common interest related to caves.
Sections are generally nationwide in scope and serve to maintain communication among the members.
A complete list of all sections, past and present, is presented in Table 5D . The Board has established four categories of ''NSS Activities. These Activities are not Internal Organizations but are intended to help members promote the purposes of the Society. Each is further defined in Appendix P of Section 3. The categories are Expeditions, Projects, Conservation Task Forces, and Conservancies.
