Beginning on the vernal equinox and ending on the day before summer solstice Jim Brandenburg captured one photograph a day to document springtime in Minnesota - we have arranged the photos chronologically in this gallery. All images were made in the state's four ecological zones: tallgrass aspen parkland, prairie grassland, deciduous forest and coniferous forest. Wildlife and quiet landscapes spanning the season are portrayed in Jim's signature minimalist style. This photo essay appeared in its entirety in the April 2016 National Geographic Magazine
