On this section of the route, you will be riding on paved state trails and two-lane roads with varying shoulder widths. The country is open with rolling wetlands of dense trees and shrubs along the lake shores. At Dalbo, the route turns east and traverses slightly rolling countryside through farmland to Osceola, Wisconsin. There is a steep climb into Osceola from the St. Croix River valley. In Wisconsin, riding near the river means hillier country along the bluffs. There is a steep descent to the St. Croix River, and a steep ascent after the bridge into Stillwater, Minnesota. This map section includes a spur into the cities of Minneapolis and St. Paul.
Until I got this map, it wasn't clear that there would be good instructions for connecting to the North Lakes route. In fact, there are, right on the map. If you're going to do the Northern Tier, but using North Lakes too, then the sequence is Northern Tier #6, North Lakes #1-3, Northern Tier #10-11. And if you take the Erie Connector, you still need all the above maps (unless you go with Google maps or AAA to make up part of your route).
In general, the Adventure Cycling maps have everything a cyclist would be interested in, except possibly internet access. They do indicate where the Libraries are, which, along with Motel locations and town population, allow a guess at where there will be access.
