4In 1861, at the age of 37, Harriet Colfax took on the job of lighthouse keeper for the Michigan City lighthouse off Lake Michigan. It was a bold and determined endeavor, especially since there were very few female lighthouse keepers in the country at that time. For 43 years, until the age of 80, Harriet kept her light burning, through storms, harsh winters, and changes in technology. This true story focuses on Harriet's commitment and determination to fulfilling her charge and living life on her own terms. Excerpts from her actual log are included.
