I don't live up there, I'm in the Minneapolis area, but I grew up in White Pine. So although I've been to Calumet many times I know it only by look. Anyway, as you are coming in on HW41 it will be on the right side. Prior to this will be a information center & a newer church. (the church is not connected with this cemetary, it just happens to be nearby...) Usually I park in the church's parking lot & walk in. There are ATV trails into the cemetary. If you cannot find the church or the trails just ask for directions from people you see. Don't be discouraged if the first persons you ask don't know of it. Just ask others.
The cemetary is bounded by two side streets, Cemetary St. & Hecla St. Remember, it is in the middle of a residental area and has been completely been reforested. So it will appear to you that you are walking into a forest that backs up to peoples homes. But this is the right area; there are headstones that are in or near the rear of peoples lots. The forest is very thick in places so if you can come in by the ATV trail you can use the "rough" mapping I did when I recorded the names. The Condon stone is easy to find as I remember because it is so big.
Good luck in your search and feel free to email me with any other questions or such.
