Weißer Stein (Eifel) 2007 the University of Liège executed measurements and found a height of 692 m (TAW, Belgian standard). The altitude meter of Google Earth caused some doubt about Signal de Botrange (694 m TAW) as Belgium's highest point because its vertical reference EGM96 deviates a couple of meters from the German Normalnull and the Belgian TAW, thereby suggesting an altitude of 701 m for the Weißer Stein. An accurate control by the Belgian National Geographic Institute in 2010 showed the Weißer Stein to be at maximum 693.3 m TAW (=691 m NN), with which it differs by less than 1 m
Interstate 694 (MN 36). The I-694–MN 36 interchange makes out a rough corner, in which I-694 switches direction from eastbound to southbound. I-694 continues south through the city of Oakdale, and finally terminates on the clockwise end at the interchange of I-94, I-494, and I-694 at the Oakdale–Woodbury city boundary line. I-694 becomes I-494 after this interchange. Mileposts on Interstate 694 are numbered to increase while traveling eastbound (clockwise). They are in sequence with the numbering of adjoining I-494, where the numbering begins and ends at the Minnesota River. Between Maple Grove and Brooklyn Center, the mileposts correspond to the beltway numbering,
