W. Elmer Ekblaw, a University of Illinois grad, was the botanist and geologist of the Crocker Land expedition. We’ve got a large collection of Crocker Land objects, notes, and photos of his, and one of my favorite things has to be his journal!
Ever the scientist, Ekblaw made a lot of notes and drawings on his Arctic observations in his personal journal. Here, you can see the drawing he made of polar bear tracks - “9 in to 12 in” wide, with a “2 ft” separation. These are “tracks when bear is not alarmed, and ambling along at a slow gait.”
