We begin in the easternmost subregions and move westwardly around the globe, crossing the equator as many as six times to explore ever shorter time periods as we continue to circle the planet. The maps of the regions and subregions change to reflect the appropriate time period.

Northeast Asia (244–675 CE): Okhotsk Mariners and Amur Frontiers
Northeast Asia includes eastern Siberia east of the Lena River to the Pacific, the Russian Far East (excluding the southern Primorsky/Vladivostok corner), northern Hokkaidō (above its southwestern peninsula), and extreme northeastern Heilongjiang.
Anchors

- northern Hokkaidō communities
Climate & Environmental Conditions
Climatic variability encouraged diversification between inland, riverine, and coastal economies.
Subsistence & Settlement
Three interconnected economic zones emerged:
- river fisheries

- interior taiga hunting
Okhotsk communities increasingly specialized in marine resources.
Technology & Material Culture
Iron tools became commonplace.
Diagnostic technologies included:
- bone harpoons
- marine hunting equipment
- improved canoes
- larger storage systems
Movement & Interaction Corridors
Regular movement linked:
- Amur basin
- Sakhalin
- Hokkaidō
- Sea of Okhotsk coastlines
Cultural & Symbolic Expressions
Bear ceremonialism and marine-oriented ritual traditions became increasingly prominent.
Environmental Adaptation & Resilience
The combination of coastal, riverine, and inland economies created exceptional resilience.
Legacy & Transition
By 675 CE, the foundations of the Okhotsk cultural sphere and later northern Hokkaidō developments were clearly established.
Northwestern North America (244–675 CE): Grease Trails, Arctic Frontiers, and Coastal Polities
Geographical Parameters
(Same as above.)
Anchors
- Norton communities
- Birnirk precursors
- Fraser Canyon towns
- Haida Gwaii
- Central Coast chiefdoms
- Cook Inlet and Prince William Sound
Climate & Environmental Conditions
Environmental variability reinforced the value of storage systems, exchange networks, and route redundancy.
Subsistence & Settlement
Three major systems became increasingly interconnected:
- Arctic marine economies
- coastal ranked villages
- interior salmon towns
Settlement permanence expanded while seasonal mobility remained important.
Technology & Material Culture
- specialized marine hunting equipment
- increasingly large canoes
- storage infrastructure
- oil technologies
- advanced woodworking
Movement & Interaction Corridors
Grease trails and coastal canoe routes intensified interaction between ecological zones.
Cultural & Symbolic Expressions
Ceremonial exchange and lineage systems strengthened across the region.
Environmental Adaptation & Resilience
Multiple overlapping transportation systems maintained stability through environmental fluctuations.
Legacy & Transition
By 675 CE, the foundations of classic Northwest Coast societies and emerging Birnirk adaptations were firmly established.
North Polynesia (244–675 CE): Approaching the Northern Ocean
Geographical Parameters
North Polynesia includes the Hawaiian Islands chain except Hawaiʻi Island (the Big Island)—principally Oʻahu, Maui, Kauaʻi, Molokaʻi, Lānaʻi, Niʻihau—and Midway Atoll.
Anchors
- Oʻahu windward valleys
- Kauaʻi channels
- Maui Nui lee shores
- Midway Atoll
Climate & Environmental Conditions
Reliable trade winds and seasonal swells increasingly favored long-range exploration.
Ecological Baseline
The islands remained effectively unoccupied.
Yet Polynesian navigational systems elsewhere reached unprecedented sophistication.
West Polynesia (244–675 CE): Chiefdom Seeds and Ocean Networks
Geographical Parameters
West Polynesia includes Hawaiʻi Island (the Big Island); Tonga (Tongatapu, Haʻapai, Vavaʻu); Samoa (Savaiʻi, Upolu, Tutuila/Manuʻa); Tuvalu and Tokelau; the Cook Islands; the Society Islands; and the Marquesas.
Anchors
- Tongatapu ceremonial centers
- Samoa lineage landscapes
- Fiji–Tonga–Samoa exchange routes
Climate & Environmental Conditions
Trade-wind routes increasingly supported long-range movement and cultural integration.
Subsistence & Settlement
Chiefly authority became increasingly visible.
Settlements expanded around:
- reef systems
- taro valleys
- canoe landings
Movement & Interaction Corridors
Robust exchange linked:
- Tonga
- Samoa
- Fiji
while exploratory voyages increasingly pushed outward.
East Micronesia (244–675 CE): Navigation Systems and Ocean Networks
Geographic Parameters
East Micronesia includes:
- Gilbert Islands (Kiribati)
- Marshall Islands (Ralik and Ratak)
- Nauru
- Kosrae
Anchors
- Marshall navigation corridors
- Gilbert chain routes
- Kosrae exchange hub
Climate & Environmental Conditions
Periodic droughts increased the importance of inter-island reciprocity and navigation.
Subsistence & Settlement
Food preservation, taro production, and reef management became increasingly sophisticated.
Movement & Interaction Corridors
Marshall and Gilbert navigation traditions matured.
Stick-chart knowledge began formalizing navigational understanding.
East Melanesia (244–675 CE): Exchange Networks and Chiefdom Precursors

Southeast Indian Ocean (244–675 CE): Ecological Consolidation
Geographic & Environmental Context
The subregion of Southeast Indian Ocean includes Kerguelen east of 70°E and Heard Island and McDonald Islands. Eastern Kerguelen’s basaltic highlands and fjord systems defined the landscape, while Heard Island’s Big Ben retained summit ice and coastal glaciers. The McDonald Islands persisted as small, volcanically active islets buffeted by constant seas.
