 Bædeker The Rhine from Rotterdam to Constance (1873) Route 46 page 253

The road now ascends more abruptly to the (3 M.) Eckle, a strip of wood on the mountain, where a stone marks the boundary between Wurtemberg and Baden, and a view of the Yosges is obtained. The road to the 1. descends to Seebach, situated on the new road through the Murgthal; a footpath only leads to the Hornisgrinde.

Three paths enter the wood at the Eckle: that most to the r., a bridle-path, leading straight to the S., forms the boundary between the above states; the second and most trodden, also inclining to the r., leads past the Drei-Filrstenstein , bearing the arms of Baden and Wurtemberg, to the summit of the Hornisgrinde. The third, path (to the Mummelsee), at first little trodden , runs parallel with the road, and after a few paces joins a broad track, which slightly ascends the hill - side ; the broad stony path ascending to the r., 10 min. from the Eckle, then leads to the lake in l fa hr.

The second of the above paths leads to the (25 min.) * Hornisgrinde (3825 ft.) , the top of which is marked by a massive stone Signal, supported by stakes. The bare and marshy summit commands a very extensive view, which however is frequently shrouded in mist : to the E. the Swabian Alb, the Achalm at Reutlingen , the Hohentwiel, and other peaks of the Hohgau ; S. the heights of the Black Forest, Feldberg, Belchen, Blauen, and beyond them even the Alps (comp. p c 272); S.W. the Kaiserstuhl (p. 244), and Vosges ; W. the vast plain of the Rhine; nearly opposite rises the spire of Strassburg, and on a mountain in the foreground the extensive ruins of the Brigittenschloss (p. 201); N. the mountains around Baden, the Mercuriusberg (p. 199), and even the Thurmberg near Durlach.
