Description

The two maps depicted here—Plan d'Une Baie sur la partie Meridionale de Whaoo and Baie d'Yam, Isle d'Oneehow—offer detailed cartographic views of two coastal regions in the Hawaiian Islands. Both were created in 1786 during the voyage of Captain George Dixon, an English explorer and fur trader.  

The two maps are:

  • Plan d'Une Baie sur la partie Meridionale de Whaoo: This map shows a sheltered bay on the southern coast of the island of Whaoo, the early spelling for Oʻahu, with soundings and navigational details indicating depths and coastal features.
  • Baie d'Yam, Isle d'Oneehow: This second map portrays the topography and coastal features of Oneehow, an early spelling for Niʻihau, with a coastal profile illustrating the island’s mountainous terrain. The map emphasizes its natural harbor, soundings for anchorage, and surrounding geographical contours.  A link to the original manuscript map can be found here:

Both maps include annotations on latitude, longitude, and magnetic declination, underscoring the scientific rigor of late 18th-century British naval surveying practices.

 These maps are tied directly to the Pacific expedition led by George Dixon and his companion Nathaniel Portlock, who were tasked by the King George’s Sound Company to explore and map the northwest coast of North America while engaging in the fur trade. During the summers of 1786 and 1787, Dixon explored the rugged coastlines of present-day British Columbia and southeastern Alaska, documenting new inlets and islands. The Hawaiian Islands served as a strategic wintering location where Dixon could repair his ship, restock provisions, and document the local geography.
