<p>For reconnaissance geologic mapping and mineral resource evaluation of the Granite Fiords wilderness study area, we developed and used a system of machine-processable field notes. Preprinted field forms standardize notes and serve as checklists that insure collection of all available data. The use of this system cut in half the time required to record data at an outcrop. The system consists of three related but<br />different types of preprinted field sheets, a key to abbreviations and codes, and a set of written instructions. The field sheets include a<br />station sheet for basic outcrop data, a specimen sheet for rock samples, and a geochemical sheet for materials to be chemically analyzed. Data on the field sheets are keypunched on standard IBM cards, then arranged in subfiles and retrieved by using a card sorter. Our system is<br />designed specifically for a region of granitic and metamorphic rocks but is easily modified for use in different geologic terranes. We offer four<br />guidelines for developing a system of machine-processable field notes: (1) Time and money spent to develop the system must be worth its<br />anticipated benefits. (2) The system should be as flexible as possible. (3) It is necessary to tailor the system to a particular geologic terrane or project objective. (4) The system should be as simple and self-explanatory as possible.</p>
