American archaeology is ready to be a mature science, one that accepts the primacy of its empirical data--for these can outlast theories--and the political and human ramifications of its actions, as it reflectively constructs and compares interpretations. Tolerance for ambiguity is as essential as the Marshalltown trowel.
