I'm pretty sure the location you have mapped this collection to is incorrect. You have put it in Sec. 23 T38N R21W, which is Rock Creek Twp, as the label specifies. However, the label also specifies that the location is 1/2 mi W of the St. Croix River, in the Chengwatana State Forest; your location is 7 mi W of the river and well outside the state forest boundary. Per these other label details, the location should be in T38N R20W, the township east of Rock Creek, but whose name I haven't been able to find. Sec 23 T38N R20W is within the state forest, but unfortunately the northeast corner of this section is a bit more than 1/2 mi W of the river; that distance puts the point in Sec 24 (also in the forest). Don't know which you would want to give greater weight to.
