In 1820, the District of Maine became an independent state. Much of northern and eastern Maine was wilderness, and the boundaries were not clearly defined. Maine’s first Governor, William King, sent Major Joseph Treat to survey the northeast section of Maine. Treat enlisted the help of John Neptune, lieutenant governor of the Penobscot tribe, to guide him across the Wabanaki homeland.
Treat kept a detailed journal chronicling their journey, describing the condition of the land, settlements, Native camps, timber resources, and evidence of illegal logging operations.
