Schwarzer_Grat
The Schwarze Grat between Eschachthal in the Bavarian county of Oberallgäu and Bolsternang in the Baden-Württemberg county of Ravensburg is 1,118 m above sea level (NHN)[1] and thus the highest mountain in Ravensburg, in the province of Tübingen (Baden-Württemberg) and the Adelegg range, although within the Adelegg region it is topped by the Ursersberg (1,129 m). An observation tower, the Schwarzer Grat Tower stands at the summit.
