A German Observation Post near Waldmohr: Foxholes, One-Man Bunkers, Earthworks, and a Machine Gun Emplacement
I found this spot 18 October 2007 walking along the old border.  Points where a road intersects a border are usually fortified,  and, sure enough, there was clear evidence of an old German OP. Unfortunately, the foxholes and MG emplacement don't photograph well but they are obvious in the forest as man-sized depressions in the underbrush.  This site is along the road between Waldmohr and Hoechen and is accessed by a 2-3 foot climb up an embankment (part of the original earthwork).
This path leads up a slight incline to the OP site. From this protected position on a high point (about size of a football field), the intersection could be watched for a hundred meters in three directions. The trees are all postwar size - wonder if it was forested in 1935?  A deep, round machine gun emplacement about  2-3 meters in diameter is just to the left at the top of the hill. Many foxholes are clearly visible about 30 meters out of the photo. Bulldozers were working within 100 meters of the site so the days may be numbered for this site! 
This photo looks back toward the location in the photo above (I was standing near the sunny area). At least ten foxholes are scattered in the forest to the right of the photo. According to the photographs in German books, the earthworks here are typical of Westwall (Siegfried Line) barriers and were cheap and easy to construct. The highway is about 30-40 meters to the left.  The German/French border made a 90 degree turn at this intersection.
The photos below show two "Einmannringkampfstands", or "Kochbunkers" located on the site.  These "one man ring battle stands" were cement cylinders sunk into the earth with an armored cement cover, first used in 1943. "Koch" was the name of the inventor.  The raised rim provided support for machine guns or Panzerfausts. They were used in observation posts and were sunk about 1 - 2 meters into the ground; some were anchored on an underground metal rod. These two stand about a foot above the ground and are completely filled in - note the tree growing out of the one!  There is a mound about 5 feet high at the east end of this area which may may be the remains of a bunker.  My neighbors say some of the bunkers in this area were not blown up until the 1960's.
