So here is the deal. With sunsets, you get there a few minutes before and can stay there till the colors disappear into darkness, however long that may be. With sunrises you don’t have that luxury. Ideally you need to get there before dawn, about an hour before sunrise. That way you have time to scope the landscape and get the camera setting close to what it needs to be. Then you can adjust the settings as the light changes. Getting there 15-20 minutes may not give you enough time to get the best shots.
That may be hard during the summer in MN, but it will definitely be worth it. And you can always go back to bed for a few more hours 
Hope you have a wondery trip with lots of beautiful sunrises (and sunsets)
CC always welcome.
