The most raised part
of the Sredne-Siberian plateau - mountains Putorana on which takes
place a route. As mountains Putorana consider a basalt plateau on
northwest suburb of the Sredne-Siberian plateau. It is stretched from
an Arctic circle almost to 71® these and from 88® to
101® century д. (More than 500 km). In these limits the area of
a province of Putorana makes 284000 клг. The average height of
mountains 900 - 1200 m, and the highest - 1701 m is in their central
part. The most typical line of mountains Putorana - a combination
платообразных the levelled surfaces of hills and deep lake hollows, and
also river valleys with каньонистыми coast. Differences in height 800 -
1000 m. In the west are most extended, the north and the east the
basalt plateau breaks sharp ledges to 300 - 500 m of height to
Western-Siberian and North Siberian plain and to a calcareous Kotujsky
plateau. To the plateau south smoothly goes down, gradually passing to
the general level of plateau with heights 500 - 700 m.
On the right side on top along a canyon
the snow terrace (f.61-63) also lasts. In 400 - 500 m from the
beginning of a canyon it rests in big snow кулуар, well looked through
with an index point.
Descent to a canyon bottom begins with
the right terrace, without reaching 100 - 150 m to snow кулуара.
Opposite to a point of the beginning of descent on the right (snow)
slope bordering a snow terrace there is a characteristic small rocky
ledge in the form of a triangle. Descent begins from a stone 1,5 х 1,5
m separately sticking out on the brink of a canyon.
All descent passes on a snow slope from
one rocky islet to another. Thus both main safety requirements are
provided: first avalanching possibility, and secondly is excluded,
safety cords are reliably fixed for rocky ledges or крючья.
The descent description:
At first 15 m downwards and to the right
(64) to a rocky ledge (the slope steepness 30-35®), then downwards
is a little to the right 50 m to. A separate stone 3 х 2 m (a steepness
35-40®). Then 40 m downwards, to the left (the steepness
45-65®, ф.65) and 10м to the right bypassing rocky breakage to a
characteristic snow pocket under a rock with which flows down small
ледопад. Here a good place for gathering ^ groups (ф.66). From here
descent of 20 m (a steepness to 45®) in долинку "ледопадного" a
stream which deduces several rather sloping (to 25®) steps on a
canyon bottom (67).
On the first sites applied перильную the
insurance: from above prior to the beginning of the most abrupt site
has been hung репшнур (70) on which went on a sliding carbine, further
- to snow кардана went on the seizing knot on a handrail from the basic
cord (50). Last abrupt 20 metres have passed with the top insurance,
and further - on foot. Last participant went on abrupt sites with the
bottom insurance.
All way of descent at first has been
seen by "scouts" from a left-bank terrace of a canyon, and then passed
completely by them. On investigation 3 hours have left, but has been
chosen and processed (протоптаны steps, are filled крючья) a safe
variant of descent (66).
