Got a nice little surprise in the mail today from the MN DNR. I had contacted them last week regarding their heavily detailed river maps, which are split into 10 maps, covering different segments of the river through out MN. We can now start planning the first state of the trip.
These maps are great, extremely detailed, and are even marked per mile. They show everything from river accessible campsites, to rapids, to dams, to portages, to fresh water fill ups. This portion of river, through Minnesota, moves significantly slower due to being more narrow and the number of dams, so we will have to plan our days accordingly.
We still need to obtain the rest of the river maps. These aren't provided by the DNR, for these we will be using the U.S. Army Corps of Engineers Navigational Charts that are available for download. I think they also make them in book format, which is something I will be searching for to purchase.
