The grand duchy had an area of and consisted of a considerable portion of the eastern half of the fertile valley of the
Rhine and of the mountains which form its boundary. The mountainous part was by far the most extensive, forming nearly 80% of the whole area. From
Lake Constance in the south to the river
Neckar in the north is a portion of the
Black Forest (), which is divided by the valley of the
Kinzig into two districts of different elevation. To the south of the Kinzig the mean height is ), and the highest summit, the
Feldberg, reaches about , while to the north the mean height is only , and the
Hornisgrinde, the culminating point of the whole, does not exceed . To the north of the Neckar is the
Odenwald Range, with a mean of , and in the
Katzenbuckel, an extreme of . Lying between the Rhine and the
Dreisam is the
Kaiserstuhl, an independent
volcanic group, nearly 16 km in length and 8 km in breadth, the highest point of which is . The greater part of Baden belongs to the basin of the Rhine, which receives upwards of twenty tributaries from the highlands; the north-eastern portion of the territory is also watered by the
Main and the Neckar. A part, however, of the eastern slope of the Black Forest belongs to the basin of the
Danube, which there takes its rise in a number of mountain streams. Among the numerous lakes which belonged to the duchy are the
Mummelsee,
Wildersee,
Eichenersee and
Schluchsee, but none of them is of any significant size.
Lake Constance (
Bodensee) belongs partly to the
German federal states (
Länder) of Baden-Württemberg and Bavaria, and partly to
Austria and
Switzerland. Owing to its physical configuration, Baden presents great extremes of heat and cold. The Rhine valley is the warmest district in Germany, but the higher elevations of the Black Forest record the greatest degrees of cold experienced in the south. The mean temperature of the Rhine valley is approximately and that of the high
table-land . July is the hottest month and January the coldest. The
mineral wealth of Baden was not great, but
iron,
coal,
lead and
zinc of excellent quality were produced;
silver,
copper,
gold,
cobalt,
vitriol and
sulfur were obtained in small quantities.
Peat was found in abundance, as well as
gypsum, china
clay,
potter's earth and
salt. The
mineral springs of Baden are still very numerous and have acquired great celebrity, those of
Baden-Baden,
Badenweiler,
Antogast,
Griesbach,
Friersbach and
Peterthal being the most frequented. In the valleys the soil is particularly fertile, yielding luxuriant crops of wheat, maize, barley,
spelt,
rye,
beans,
potatoes,
flax,
hemp,
hops,
beetroot and tobacco; and even in the more mountainous part,
rye, wheat and
oats are extensively cultivated. There is a considerable extent of pasture-land, and the rearing of cattle, sheep, pigs and
goats is extensively practised. Of
game,
deer,
boar,
snipe and wild
partridges are fairly abundant, while the mountain streams yield
trout of excellent quality. Viticulture is increasing, and the
wines continue to sell well. The
Baden wine region is Germany's third largest in terms of vineyard surface. The
gardens and the
orchards supply an abundance of fruit, especially
sweet cherries,
plums,
apples and
walnuts, and
bee-keeping is practised throughout the country. A greater proportion of Baden than any other south German state is occupied by forests. In these, the predominant trees are
European beech and
silver fir, but many others, such as
sweet chestnut,
Scots pine,
Norway spruce and the exotic
coast Douglas-fir, are well represented. A third, at least, of the annual
timber production is exported. ==Army==
