Northern Black Forest
Even the highland areas of the Northern Black Forest around the Hornisgrinde and the Kniebis have used the term in tourist advertising. In addition, official Baden and Württemberg geology publications of the 1930s described the higher regions of the Northern Black Forest as the "Hochschwarzwald" in contrast with the sunken blocks on its perimeter along the fault lines and the tectonically less uplifted Central Black Forest.
