The SSntis-Relief 1 : 5000, by Prof. Alb. Heim 

 in Ziirich. 



Whereas we have become acquainted, at No. 16, 

 with the oldest Eelief, the origin of which dates from 

 1766 1780, we are now standing before the youngest 

 creation of this kind of technics with its eminent im- 

 provements. 



Prof. Heim writes about it as follows : 



The group of the Santis is a cluster of steep folds 

 formed by the strata or layers of the cretaceous system. 

 As a group of folds it can serve as a typical example of 

 a chain of mountains. 



The most southern fold, extending throughout the re- 

 lief is that of Gulmen. In its western part the upper chalk 

 is worn, but the ,,schratten" chalk exists in the shape of 

 a closed vault. A deep valley (Mulde) Teselalp-Rosenalp, 

 separates the first vault from the adjacent western vault. 

 The next northern valley appears in the Wildhaus Schaf- 

 berg, and in the Querkamm of the Moor, and runs down 

 into the deep basin of the lake of Fiihlen. The fourth 

 vault rises in steep calcareous slabs out of the lake of 

 Fahlen, in the direction of the Hundstein. Its southern 

 flank forms, in the ,,Schratten u chalk, the Altmann. The 

 fifth vault, coming from the east, rises on the northern 

 margin of the lake of Seealp. In the back-ground of the 

 Seealp, we see it splendidly through an oblique opening, 

 disclosed in the neocom-bend. It projects just below the 

 summit of the Santis, which is left standing on the top of 

 the vault like a saddle-shaped bridge of the upper layer of 

 chalk. Between the Santis and the peak of Gire, the most 

 beautiful fanshaped valley (Mulde) of the Sewer chalks is 

 to be seen. Then follows the northern edge of the moun- 

 tain, the complicated formation of the North Vault, that 

 forms on its steep flanks the Silberblatt, the peak of Gire, 

 Turme etc., in its back the Gartenalp, Ebenalp, Bommeralp. 



A very great horizontal, transversal shifting is notice- 

 able "through the whole chain. Various and numerous 

 are the hundreds of interesting technical details of this
