Chapters generally hold regular meetings and trips, organize projects, train new members, publish newsletters, and provide social functions for their members. A special type of chapter, a student grotto, can be organized at an educational institution to serve the needs of students, staff, and faculty at that institution. A complete list of all chapters, past and present, is presented in Table 5A . Regional Associations, or Regions, are Internal Organizations made up of grottos, sections, surveys, and individuals in a general geographical area. The purpose of a region is to maintain communication among Internal Organizations and isolated members whose speleological interests cover the same general area.
Most regions organize at least one annual project, meeting, or get-together.
Some regions also publish a newsletter. A complete list of all regions, past and present, is presented in Table 5B . 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 .
