“…There is more to settlement mobility than such an island-wide approach can take into account, including movement to smaller seasonal and special purpose sites (see Kennett 2005;Jazwa et al 2015a). Finally, we note that Santa Rosa Island includes only relatively high-ranked settlements.…”

“…At Dry and Soledad Canyons, this includes units at CA-SRI-19 and CA-SRI-821. Similarly, CA-SRI-3 and CA-SRI-5 at the mouth of Tecolote and Arlington Canyons were both occupied during the middle Holocene (Kennett 1998;Winterhalder et al 2010;Jazwa et al 2015a). Intensive settlement persists at both of these locations through the late Holocene (prediction 4).…”

“…The earliest known occupants of these islands targeted fish, shellfish, and sea mammals such as pinnipeds and dolphins. During the middle Holocene (7550-3600 cal BP), a distinctive settlement system included large coastal settlement sites at the mouths of major streams, interior residential bases, and special purpose sites for collecting and shucking abalones (Clifford 2001;Kennett and Clifford 2004;Jazwa et al 2015a). This system was primarily concentrated on the resource-rich north coast of Santa Rosa Island, with the exception of a series of abalone shucking sites on the west coast.…”

“…Despite the fact that Bee Canyon does not have evidence of permanent occupation until relatively late, people were there for short periods of time during the middle Holocene. CA-SRI-338 is a special purpose red abalone shucking site dating to ∼5900-5700 cal BP (Jazwa et al 2015a). Several other similar red abalone middens are located farther to the south near the mouth of Acapulco Canyon.…”

Using targeted survey, excavation, and radiocarbon dating, we assess the extent to which human settlement patterns on California's northern Channel Islands fit predictions arising from the ideal free distribution (IFD): (1) people first established and expanded permanent settlements in the regions ranked high for environmental resource suitability; (2) as population grew, they settled in progressively lower ranked habitats; and (3) changes in the archaeological record associated with high population levels such as increases in faunal diversity and evenness in high-ranked habitats are coincident with the expansion to other areas. On Santa Rosa Island, the early permanent settlements were located in both high-and middle-ranked locations, with the most extensive settlement at the highest ranked locations and only isolated sites elsewhere. Settlement at a low-ranked habitat was confined to the late Holocene (after 3600 cal BP). Drought influenced the relative rank of different locations, which is an example of climate adding a temporal dimension to the model that episodically stimulated population movement and habitat abandonment. Because the IFD includes a wide range of cultural and environmental variables, it has the potential to be a central model for guiding archaeological analysis and targeted field research.

Hydrological Modeling and Prehistoric Settlement on Santa Rosa Island, California, USA

Fresh water availability was an important variable that influenced prehistoric human settlement on California's northern Channel Islands. Previous attempts to understand settlement on the islands use watershed size as a proxy for water at canyon mouths. In semi‐arid regions, this approach has limitations because streams may lose much or all of their flow to groundwater. We developed a distributed hydrological model for Santa Rosa Island that incorporates geospatial and temporal data for climate (precipitation, solar radiation, wind speed, relative humidity, temperature), soils, vegetation, and topography to simulate the complex land‐surface‐groundwater behavior of island hydrology for hypothetical wet, dry, and median centuries. Our simulations show that water flow is greatest in drainages on the northwest and east coasts of the island. This correlates with some of the earliest and most persistent settlement on the island. During the most extreme droughts of the last 2000 years during the Medieval Climatic Anomaly (1150–600 cal BP), island populations contracted to a small number of large coastal villages. We argue that this was related in part to the greater availability of surface water at these locations. This study expands the theoretical and methodological scope of past studies that have applied hydrological simulation to archaeological investigations.
