Prehispanic and early historic archaeological information for the Malpai Borderlands of southwest New Mexico and southeast Arizona is reviewed using data derived from field reconnaissance, discussion with relevant scholars, archival resources from varied agencies and institutions, and published literature. Previous regional research has focused on late prehistory (A.D. 1200 to 1450), shaping the scope of cultural historical overview and providing an opportunity to examine relationships with Casas Grandes (Paquime) to the south. A second important objective of current study is the exploration of prehispanic and early historic human impacts to Borderlands ecosystems, particularly in relation fire ecology. A recommended sequence of future research is intended to address significant questions surrounding both culture history and anthropogenic environments in the Malpai Borderlands.

The purpose of this study was to compare current woodland density and distribution in and around the dry upper Verde River watershed in northwestern Arizona with conditions prior to Anglo settlement. Historic conditions were assessed using early photographs and early diaries and reports. The expedition led by Amiel Weeks Whipple was retraced and areas described in 1854 compared with the present. Diaries and reports of members of the Sitgreaves (1851) and Ives (1858) expeditions, Francis Aubry (1857), Edward Beale, John Marion (1870), and Edgar Mearns were also used to assess presettlement woodland conditions. Photographs from 1867, 1871, 1910, and 1917 were repeated between 1995 and 1999. Based upon these early sources, I hypothesize that the aerial distribution of woodlands have not changed greatly since 1851, although densities within many stands have increased. I conclude that at least three dense stands of woodland of unknown extent existed in the study area as early as 1851.

This study focuses on the cultural-historical environment of the 88,900-acre (35,560-ha) Valles Caldera National Preserve (VCNP) over the past four centuries of Spanish, Mexican, and U.S. governance. It includes a review and synthesis of available published and unpublished historical, ethnohistorical, and ethnographic literature about the human occupation of the area now contained within the VCNP. Documents include historical maps, texts, letters, diaries, business records, photographs, land and mineral patents, and court testimony.
