AbstractThe Mockingbird Gap Clovis site is a surface archaeological site located along Chupadera Draw in central New Mexico. Coring of the draw during archaeological investigation of the Clovis assemblage on the adjacent uplands revealed evidence for a regionally rare continuous, stratified depositional record beginning immediately before the Younger Dryas chronozone (YDC). Thirty sediment samples from the draw adjacent to the archaeological site were analyzed for microinvertebrates (ostracodes and mollusks) and gyrogonites (calcareous algae) to reconstruct its environmental history. Wet-dry cycles marked the presence/absence of microfossils. Based upon microfossils, this investigation highlights environmental change marked by the evolution from wetter/cooler to warmer/drier conditions at the Mockingbird Gap site and its response to climate change and groundwater fluctuations during and after the YDC. Four biofacies are recognized: the pre-Ciénega setting is sterile. Holarctic species near the base of core 08-1 indicate cooling conditions prior to 13,000 cal yr BP during the early Ciénega phase. Warmer, more saline conditions characterize the late-Ciénega biofacies between 11,000 and 10,000 cal yr BP. Presence of gypsum during formation of the post-Ciénega phase and the most salinity tolerant species after 10,000 cal yr BP is consistent with the aridification typifying the early Holocene.

American tourism in Mexico increased significantly during the Good Neighbor era. By creating tourist maps, cartographers on both sides of the border participated in an intentional, ideological process of reshaping these tourists’ views of Mexico. They sought to transform Americans’ perceptions not only of Mexicans and their history but also of the physical environment. Their Mexico was a place of contrast, suspended in the romantic past and engaged in modernity. Although cartographers constructed a new Mexico through their maps, they did not challenge perceptions of an asymmetrical power dynamic that had defined U.S.-Mexico relations and the tourism industry at large. Instead, their maps reinforced, reproduced, and contributed to it. Cartographers, like the maps they created, were not passive or inconsequential actors. Analyzing the ideas, relationships, and myths embedded in their maps expands our understanding of transnational tourism, environmental change, selective history, and imagined communities in the twentieth century.
