I am presently the Heritage Program Manager for Montana State Parks.
My research places me at the forefront of the burgeoning field of high elevation archaeology in the West. In my dissertation, I have assembled the first high elevation database large enough to test the common contention that ancient people used the Rockies as refugia from extreme climatic or population pressure at lower elevations.
My dissertation also considers three other foundational issues in high elevation and surface archaeology. First, I use stone tool collections from several major intermontane stratified sites to refine the Plains Typology for the mountains of the Greater Yellowstone Ecosystem (GYE). Additionally, I use obsidian source data to consider whether mountain people were a single, unified group, or were represented by a variety of peoples divided by zones of social-boundary defense. And third, I use lithic raw material and tool types to consider how much of their seasonal round people were spending at high elevations in prehistory.
I obtained my BA in English from the University of Puget Sound in 2009, and my MA in Anthropology from the University of Wyoming in 2011. My Master's thesis was on ice patch archaeology all around the world, and the patterns of high altitude use suggested by artifacts found melting from the ice in recent years. As part of that project, I worked with Drs. Robert Kelly, Craig Lee and Pei-Lin Yu on a ground-breaking ice patch archaeology project in Glacier National Park, in collaboration with the Confederated Salish and Kootenai Tribes and the Blackfeet Nation. This project was awarded the Department of the Interior's Partners in Conservation Award for tribal collaboration. I worked seasonally for the US Forest Service throughout my Bachelor's and Master's degree, and in 2011 I returned to work for the Forest Service full time, first as a Zoned District Archaeologist and then as an acting Forest Archaeologist on the Kootenai National Forest of Montana. I left that position to begin my PhD studies in 2014.edit

Hunting and gathering is, evolutionarily, the defining subsistence strategy of our species. Studying how children learn foraging skills can, therefore, provide us with key data to test theories about the evolution of human life history, cognition, and social behavior. Modern foragers, with their vast cultural and environmental diversity, have mostly been studied individually. However, cross-cultural studies allow us to extrapolate forager-wide trends in how, when, and from whom hunter-gatherer children learn their subsistence skills. We perform a meta-ethnography, which allows us to systematically extract, summarize, and compare both quantitative and qualitative literature. We found 58 publications focusing on learning subsistence skills. Learning begins early in infancy, when parents take children on foraging expeditions and give them toy versions of tools. In early and middle childhood, children transition into the multi-age playgroup, where they learn skills through play, observa...

A key issue distinguishing prominent evolutionary models of human life history is whether prolonged childhood evolved to facilitate learning in a skill- and strength-intensive foraging niche requiring high levels of cooperation. Considering the diversity of environments humans inhabit, children’s activities should also reflect local social and ecological opportunities and constraints. To better understand our species’ developmental plasticity, the present paper compiled a time allocation dataset for children and adolescents from twelve hunter-gatherer and mixed-subsistence forager societies (n = 690; 3–18 years; 52% girls). We investigated how environmental factors, local ecological risk, and men and women’s relative energetic contributions were associated with cross-cultural variation in child and adolescent time allocation to childcare, food production, domestic work, and play. Annual precipitation, annual mean temperature, and net primary productivity were not strongly associated...

Forager societies tend to value egalitarianism, cooperative autonomy, and sharing. Furthermore, foragers exhibit a strong gendered division of labor. However, few studies have employed a cross-cultural approach to understand how forager children learn social and gender norms. To address this gap, we perform a meta-ethnography, which allows for the systematic extraction, synthesis, and comparison of quantitative and qualitative publications. In all, 77 publications met our inclusion criteria. These suggest that sharing is actively taught in infancy. In early childhood, children transition to the playgroup, signifying their increased autonomy. Cooperative behaviors are learned through play. At the end of middle childhood, children self-segregate into same-sex groups and begin to perform gender-specific tasks. We find evidence that foragers actively teach children social norms, and that, with sedentarization, teaching, through direct instruction and task assignment, replaces imitation ...

Theoretical engagement and methodological innovations geared towards identifying the presence and activities of children in archaeological contexts has increased in pace over the last decade. This paper presents a systematic review of the literature pertaining to the archaeology of hunter-gatherer children. The review summarises methods and findings from 72 archaeological publications in a number of research areas that show material culture relating to childhood, including children’s playthings and tools, learning to flintknap, and their involvement in the making of marks, art and footprints. By drawing on diverse evidence from all inhabited continents, we explore the implications of these data for our understanding of the cultural variability and patterning of hunter-gatherer children in the deep past. The paper closes by discussing potential improvements to archaeological and anthropological methodologies which would progress our understanding of children as active and engaged mem...

Abstract This paper offers a method for estimating relative occupational duration at high elevations using lithic tool and raw material diversity. Presuming high elevation occupations are seasonal, we adapt methods traditionally used to estimate occupational duration for individual sites to the scale of landscapes, using data from the Beartooth and Absaroka Mountains of the Greater Yellowstone Ecosystem. Essentially, we work to understand how much of foragers’ seasonal rounds they were spending at high elevations. Averaged over the Holocene, the Beartooths appear to experience longer high elevation occupational duration than the Absarokas. In addition, Beartooths occupational durations are longest during the Early Archaic, likely related to the Early Holocene Warming. In the Absarokas, meanwhile, occupational durations are longest during the cooler, wetter Middle Archaic. Indeed, seasonal occupational durations consistently differ between the two ranges, suggesting diversity in mountain adaptations despite their similarities in resources and climate. Finally, the evidence suggests a gradual mid-to-late Holocene migration of Shoshonean peoples from the south and west rather than a sudden, unidirectional Numic Expansion.

Understanding how socioecology affects contemporary children’s learning and work opportunities can help researchers better model the selection pressures which have shaped the evolution of human life history and social organization. Here, we compiled a global time allocation dataset for children and adolescents from hunter-gatherer and mixed-subsistence societies. We investigated how society-level variables including adult sexual division of labour, ecological risk, and climate related to variation in childcare, food production, domestic work, and play. We found that adult sexual division of labour predicted increased sex differences in time allocation, especially childcare. Children in safer ecologies allocated more time to childcare and domestic work, but ecological risk did not strongly predict participation in food production. Climate did not predict child and adolescent time allocation. We argue that by coordinating labour across age and sex, children may simultaneously learn to...

Archaeologists worldwide know very little about the immense ecosystem changes already underway in the mountains and the threats that anthropogenic climate change poses to high elevation cultural resources. So how do we proceed? What do we prioritize? Is high elevation ice resilient to these changing climates, and if so, how much? How much time do we have before mid-latitude high elevation ice disappears entirely? This paper comments on the impacts of climate change to high elevation cultural resources, particularly ice patches, whose presence as a constant source of water is vital to the general appeal of high elevations for human occupation. Beyond their ecological importance, ice patches can also preserve ancient organic artifacts and paleobiological material for over 10,000 years. And they are melting rapidly thanks to anthropogenic climate change. This paper offers a case study of two groups of archaeologically productive high elevation ice patches from the Greater Yellowstone Ecosystem, analyzing their resiliency in the face of warming temperatures and changing climates. Ultimately, I conclude that high elevation patches of ice and snow may be losing their resiliency to warmer temperatures as their ancient ice melts, making them ever more vulnerable to climate change. Ice patch researchers are in a race against time to identify productive ice patches and recover any fragile artifacts or paleobiological material they may contain before they melt completely. For many of these patches, this would be their first complete melt since the early Holocene.

In recent years, in association with global climate change, researchers have found significant quantities of preserved archaeological material melting from kinetically- stable alpine and subalpine ‘ice patches’ all around the world. This paper synthesizes the findings and the methodologies of ice patch archaeology worldwide thus far in an effort to provide researchers with a broadened perspective on artifact collection and interpretation. In addition, I test the hypothesis that increased quantities of alpine ice in prehistory should correlate with decreased human use of these areas, and vice versa. I analyze the rela- tionship between the frequencies of regional artifact dates over time, the nature of these artifacts, and glacial advances and retreats. Ultimately, I conclude that fundamental dif- ferences among these assemblages and their correlation (or lack thereof) with prehistoric alpine ice extents stem from the intention and the activity of the people who deposited the artifacts.
