For a while, it seemed the series of experimental aircraft sponsored by the U.S. government had run its course. Between the late 1940s and the late 1970s, almost thirty designations had been allocated to aircraft meant to explore new flight regimes or untried technologies. Then, largely, it ended. But there was a resurgence in the mid- to late- 1990s, and as we enter the fourth year of the new millennia, the designations are up to X-50.

Ancestral Mounds deconstructs earthen mounds and myths in examining their importance in contemporary Native communities. Two centuries of academic scholarship regarding mounds have examined who, what, where, when, and how, but no serious investigations have addressed the basic question, why? Drawing on ethnographic and archaeological studies, Jay Miller explores the wide-ranging themes and variations of mounds, from those built thousands of years ago to contemporary mounds, focusing on Native southeastern and Oklahoma towns. Native peoples continue to build and refurbish mounds each summer as part of their New Year's celebrations to honor and give thanks for ripening maize and other crops and to offer public atonement. The mound is the heart of the Native community, which is sustained by song, dance, labor, and prayer. The basic purpose of mounds across North America is the same: to serve as a locus where community effort can be engaged in creating a monument of vitality and a safe haven in the volatile world.
