to Goschenen. OBERALP. 92. Route. 339
Calmot on the right. The Vorder-Rhein (Aua da Toma, or Darvun)
descends in a series of falls from the slope to the left.
Source of the Vorder-Rhein. The Vorder-Rhein rises in the Toma-See
(7690'), on the N.E. slope of the Six-Madiin or Badus (p. 203). The path
to the lake (guide advisable) diverges from the road to the left, l'/i M.
above Chiamut (see above); near the Alji Milez it crosses the brook emerg¬
ing from the Val Surpalix, and ascends to the C/2 hr.) Alp Tgiellems.
Above this Alp (avoid path to the left, crossing the brook) we ascend
the pastures to the right, on the left bank of the Fil Toma, the brook
descending from Piz Nurschallas. After about 1 hr. we turn to the left
and soon reach the rocky barrier behind which the lake lies. The Toma-
See (2'/2 hrs. from Chiamut), a green lake, very deep, and destitute of
fish, about 270 yds. long and 130 yds. broad, is bounded on the S. and
S.W. sides by precipitous rocks and stony slopes, and on the N. and N.W.
by pastures. The 'Badus (9616'; comp. p. 103) cannot be ascended direct
from the lake , the rocks being here too steep; but by going round to the
N. side we may reach the top without much difficulty in 2 hrs. (guide 10 fr.).
The Piz Nurschallas (9003'), running out from the Badus to the N.
(from (he Oberalp Pass 2, from Chiamut 3'/2 hrs.; guide unnecessary), is
easy and interesting. We follow the Toma-See route, diverge to the right
where it turns to the left, ascend steep pastures, and lastly mount the
broad S. arete to the summit. Superb survey of the Reuss and Vorder-
Rhein valleys and the mountains enclosing them. Easy descent to the
Oberalp Pass, l'/i hr.
To the S. of Chiamut the Val Gornera, the mouth of which is a
pithless ravine, ascends to the frontier chain of Ticino, and from it the
Val Maigels diverges to the W., f/2 hr. from Chiamut. Toilsome routes
lead from the Val Cornera over the Passo Vecchio (8908') to the Val Cad-
limo and Piora (p. 98); from the Val Maigels, to the S., over the Passo
I'ian Bornengo (8649') to the Val Canaria and Airolo (p. 98); and to the
W., over the Maigels Pass (7940') and the Lohlen Pass (7835'), to the Unter-
alpthal and Andermatt (p. 103).
The road ascends the sequestered Val Surpalix in long windings
(which paths cut off; one ascending to the left by the first bend,
and bearing to the right, leads to the pass in 3/4 hr.). It affords
views of the Crispalt and Berglistock, and of the Piz Cavradi, Piz
dell' Ufiern, and Piz Ravetsch behind us. The (52 M.) Oberalp
Pass (6732'), 3'/2 M. from Chiamut, forms the boundary between
the Grisons and Uri. Extensive turf-diggings. (The diligence as¬
cends to the pass from Chiamut in 50 min.; descent 30 min. ;
descent to Andermatt 1 hr. 10 min., ascent 2 hrs.)
The road skirts the N. bank of the sombre Oberalpsee (6654';
1 M. long), abounding in trout, the outlet of which is one of the
chief sources of the Reuss, and then traverses the nearly level Ober¬
alp (6443'). About 3 M. from the pass we obtain a view of the
Ursernthal, with the Furka towards the W. (p. 108). The old path
descending here to the left direct to (*/2 hr.) Andermatt is steep
and stony, and affords little view. The road remains on the hill a
little longer, and then descends by nine long windings to (6 M. from
the lake) ■—
59 M. Andermatt (4738'); thence to (4 M.) —
