Utqiaġvik
The Iñupiat community of Utqiaġvik is located on the northernmost tip of Alaska between the Chukchi and Beaufort Seas. It is the largest community on the North Slope of Alaska and is a hub for smaller villages in the region and for scientists doing Arctic research.
Utqiaġvik is a whaling community, and many of the activities occurring throughout the year are relevant to the preparation for either the fall or spring whale hunt. Fall whaling generally occurs during the month of October while spring whaling occurs from March to May, depending on ocean and sea ice conditions.
Utqiaġvik is also a hotspot for migratory birds due to the unique climate and geography of the region. Travel access and subsistence activities are heavily influenced by wind and weather patterns which control local ocean and sea ice conditions.

About seasonal calendars
The outer bands track ice safety, showing safe travel on sea and lagoon ice from roughly December through April, break-up and open water during summer, and freeze-up in autumn.
The inner rings map harvesting windows for wildlife: caribou and ice fishing span late autumn to winter; geese, seals (ringed and bearded), and whales (beluga and bowhead) are hunted during spring and summer open-water periods; and rod fishing and berry gathering occur in late summer.
