As noted on the full photo set page, this is Benjamin Jacob Odawa Littlecreek, who was available at Lake Itasca during the summers presumably as a tourist attraction, based on this blurb from the Austin Daily Herald from March of 1955: https://www.flickr.com/photos/photolibrarian/8036601324/in/photostream/
The Minnesota Historical society has a few items related to him, notably a color photo: http://collections.mnhs.org/cms/largerimage?irn=10253900&catirn=10766855&return=brand%3Dcms%26q%3Dlittlecreek and a postcard of him at the headwaters: http://collections.mnhs.org/cms/largerimage?irn=10145620&catirn=10780262&return=brand%3Dcms%26q%3Dlittlecreek
