h6. Comments:
Die Entenlochklamm wird von der Tiroler Ache durchflossen, die den „Kaiserwinkel" im nördlichen Vorland des Kaisergebirges (genauer des Zahmen Kaisers) entwässert. Dort stehen deformierte und leicht metamorphisierte klastisch-karbonatische Gesteine der triassischen Kössener Schichten an. Probenpunkt an einer schmalen, hochgelegenen, ca. 50 m langen Sandbank am stromabwärtigen Ende der Klamm.
