All theories of the “peopling” of the Western Hemisphere acknowledge the abundant evidence, from remotest pre-Columbian times to the present, that American Indians have traveled long distances for direct subsistence, trade, and other purposes. Yet most Indian societies have not produced “maps” in the familiar sense of “a representation, usually on a plane surface, of a region of the earth or heavens.” Outside the influence of European colonizers, and with the pre-Columbian exception of urbanized Mesoamerican groups, these groups have relied mainly on speech and memory to transmit and store important information, including knowledge about the earth’s surface and wayfinding on it. Scholars working within Eurocentric traditions of keeping written records have documented some of these spoken and memorized portrayals of the earth’s surface.
Today scholars, especially geographers, recognize a variety of ways that human societies represent the earth and heavens, as the following definitions of “map” attest: According to J. B. Harley, “Maps are graphic representations that facilitate a spatial understanding of things, concepts, conditions, processes, or events in the human world.” More than mere “representations,” states Denis Wood, maps are social constructions that “make present—they re-present—the accumulated thought and labor of the past . . . about the milieu we simultaneously live in and collaborate on bringing [into] being. . . . they enable the past to become part of our living. . . . (This is how maps facilitate the reproduction of the culture that brings them into being).” These constructions have many forms, both tangible (visual, “artifactual”) and intangible (verbal, “mental,” performed). Intangible maps include the cognitive maps that each person constructs mentally from direct experience and other sources (often traditional). They also include verbal maps, that is, constructions of the earth’s surface in spoken forms, such as descriptions or narratives. Much of the literature on verbal maps, at least those of American Indians, concerns place-names and how they organize information associated with the places, including memorized strings of placenames used to mark travel corridors.
