⚠️ Disputed: the sources disagree.

What it is

A canoe of redwood or pine planks lashed with fibre cords and sealed with natural asphalt, 6 to 9 m long, in which the Chumash sailed between the mainland and the Channel Islands. It is one of the few sewn-plank craft in the Americas.

The date of appearance is debated: some authors place it around AD 500 and others around AD 1150 (period of medieval droughts). Wood finds are scarce.

What it led to

  • shell-bead trade and offshore fishing between islands and coast
  • social complexity of the Chumash chiefdoms
  • today's revival with tomol crossings to Santa Cruz Island
