Passage 45
Maps made by non-Native Americans to depict¹ Native American land tenure², resources and
population distributions appeared almost as early as Europeans’ first encounters with Native
Americans and took many form: missionaries’ field sketches³, explorers’ drawings, and surveyors’
maps, as well as maps rendered in connection with treaties involving land transfers. Most existing
maps of Native American lands are reconstructions⁴ that are based largely on archaeology⁵, oral
reports, and evidence gathered from observers’ accounts in letter, diaries, and official reports;
accordingly, the accuracy of these maps is especially dependent on the mapmakers’ own
interpretive abilities.
Many existing maps also reflect the 150-year role of the Bureau of Indian Affairs (BIA) in
administering tribal⁶ lands. Though these maps incorporate some information gleaned⁷ directly from
Native Americans, rarely has Native American cartography contributed to this official record,
which has been compiled, surveyed, and authenticated⁸ by non-Native American tribes and their
migrations⁹ and cultural features, as well as territoriality¹⁰ and contemporary trust lands, reflects the
origins of the data, the mixed purposes for which the maps have been prepared, and changes both I
United States government policy and in non-Native Americans’ attitudes toward an understanding
of Native Americans.

(A)   A chronology of the development of different methods for mapping Native Americans
(B)    A discussion of how the mapmaking techniques of Native Americans differed from those of Europeans
(C)    An argument concerning the presenta-day uses to which historical maps of Native American lands are put

(D)    changes in wys that tribal lands are used (D)

270. The passage suggests which of the following about most existing maps of Native American
lands?
(A)   They do not record the migrations of Native American tribes.
(B)    They have been preserved primarily because of their connection with treaties involving land transfers.
(C)    They tend to reflect archaeological evidence that has become outdated¹².
(D)    They tend to be less accurate when they are based on oral reports than when they are based on written documents. (E)
(E)     They are not based primarily on the mapmakers’ firsthand oberservations of Native American lands.
 
271. All of the following are examples of the type of evidence used in creating “Most existing
maps” (line 7-8) EXCEPT
(A)   a nineteenth-century governemtn report on population distribtuion of a particular tribe
(B)    taped conversations with people who lived on Native America ntribal lands in the early twentieth century
(C)    aerial photographs of geological features of lands inhabited by Native Americans
(D)    findings from a recently excavated site once inhabited by a certain Native American people (C)
