Signalling and Mobility: Understanding Stylistic Diversity in the Rock Art of a Great Basin Cultural Landscape

This paper explores Great Basin arid-zone hunter–forager rock art as signalling behaviour. The rock art in Lincoln County, Nevada, is the focus, and this symbolic repertoire is analysed within its broader archaeological and ethnographic contexts. This paper mobilises an explicitly theoretical approach which integrates human behavioural ecology (HBE) and the precepts of information exchange theory (IET), generating assumptions about style and signalling behaviour based on hunter–forager mobility patterns. An archaeological approach is deployed to contextualise two characteristic regional motifs—the Pahranagat solid-bodied and patterned-bodied anthropomorphs. Contemporary Great Basin Native American communities see Great Basin rock writing through a shamanistic ritual explanatory framework, and these figures are understood to be a powerful spirit figure, the Water Baby, and their attendant shamans’ helpers. This analysis proposes an integrated model to understand Great Basin symbolic behaviours through the Holocene: taking a dialogical approach to travel backward from the present to meet the archaeological past. The recursive nature of rock art imagery and its iterative activation by following generations allows for multiple interpretive frameworks to explain Great Basin hunter–forager and subsequent horticulturalist signalling behaviours over the past ca. 15,000 years.
