Well, I did a search of the image, and I think it's Henry Mayhew, Grand Marais pioneer. (The Mayhew Inn has this image on its website, but I couldn't find it labeled. If you scroll through the images, you'll see other images that appear to be the same man.) There's another picture of the man here, I think.



And here's a quote from the Mayhew Inn regarding the man: 

Henry Mayhew was an explorer, pioneer-prospector, land speculator, fur-trader, entrepreneur and county commissioner credited with developing The Gunflint Trail and the City of Grand Marais. By 1873 Henry Mayhew, Dr. Thomas Mayhew and Samuel Howenstine owned all of the land comprising the original village of Grand Marais. Henry, along with his brother Dr. Thomas Mayhew, owned property in Grand Marais that served as a trading post, general store and doctors office. This store was located in the approximate location of the current Coast Guard Station. By 1875 Henry Mayhew constructed the first overland trail from Grand Marais to the border lakes which is now known as The Gunflint Trail. Their brother, Joseph Mayhew, was the first lighthouse keeper in 1886. The Mayhew family had a homestead on the East Bay, and built the first lodging establishment in Grand Marais called The Mayhew Hotel. The Mayhew’s old homestead has appropriately been converted into the now Cook County Historical Society & Museum.
