The three brief items that comprise this installment of Lost and Found each describes a rare and rather unusual type of archaeological site that seems so far to have been relatively neglected in the literature. The first article, from the Los Angeles Times, is an early account of a site in Nevada's Arrow Canyon Wilderness Area, in an area that is also characterized by considerable biodiversity and a great deal of rock art. The second, reprinted from Arizona Highways, discusses a site in central Arizona that is situated in a somewhat different context from the others. The third, which is reprinted from the Pacific Coast Archaeological Society Quarterly, describes a site in Anza-Borrego Desert State Park that is currently being restudied by Joan Schneider. Two other, similar sites are reputed to be located in Death Valley and Baja California, respectively (P. Wilke, personal communication 2007). Please note that a number of photographs that originally accompanied the last two articles could not be adequately reproduced here and have been deleted; interested readers are urged to consult the original articles, which are readily available in most libraries
