Summit Description
The summit 1159 (Dinozavr Glavnyy) is located in the Rai-Iz mountain massif of the Polar Urals, within the Yamalo-Nenets Autonomous Okrug of the Russian Federation beyond the Arctic Circle.
A characteristic feature of the routes to this summit via the northern wall of the western ridge are complex rock buttresses with an abundance of various rock relief, from small inclined walls and slabs to prolonged internal corners, often ending in cornices at the beginning, and prolonged movement along a heavily destroyed, rocky- talus ridge when ascending to the summit. A feature of the Polar Urals summits is that the complexity increases sequentially from the start of the route to the summit tower.
The height difference from the start of the route (mark at the water's edge at the base camp in the Nyrdvomyn-Shor river valley above sea level 199 m, summit — 1159 m) is more than 800 m.
The summit 1159 (Dinozavr Glavnyy) is included in the list of classified summits. The first routes to this summit were laid by Ukhta climbers in the winter seasons of 95–99. They also gave the summit its climbing name, as this summit does not have an independent name.
From the Nyrdvomyn-Shor stream valley, the most convenient location for a base camp — a large larch-alder oasis in the tundra — the summit is easily recognizable by its pronounced rock walls and buttresses of the northern and northern wall of the western ridge.

Route Description
The route: The first buttress of the central rock massif of the northern wall of the western ridge of summit 1159 (Dinozavr Glavnyy) resembles a triangle. This buttress is the closest to the summit. From the base camp in the Nyrdvomyn-Shor river valley, it is clearly visible.
Approach: Moving from the bivouac in the Nyrdvomyn-Shor river valley (see attached map-diagram), ford the Nyrdvomyn-Shor river, go around the green bald mountain to the right (in the direction of travel), and ascend along the snowy (talus) fields to a large rock remnant. From it, to the left in the direction of travel, traverse along the talus slopes, along the snowy fields, approach the rocky slope of the first (from left to right from the summit) buttress of the central rock massif of the western ridge. At the base of the buttress on the large-block talus, organize a rope team.
A characteristic landmark at the start of the route — there is no clearly visible landmark, but the smoothed wall of the left slope suggests a logical move to the right in the direction of travel towards a pronounced rock rib.
Technical Part of the Route
To the right of the smoothed monoliths along a clearly visible rock rib, pass to an inclined wall. On the left on the ridge, a characteristic gendarme "Ushi" is visible.
Along the inclined wall with an abundance of cracks and ledges, approach the base of an internal corner. Along the internal corner, rocks of medium complexity, bypass to the right a rock mirror and exit under a wall with a crevice. The inclined wall with a crevice is passed head-on and leads to a long inclined oblique shelf going left onto the ridge of the buttress.
Along the shelf, approach under the first rock tower. The tower is limited by drops into couloirs. It is passed head-on along rocks of medium complexity.
From the tower, along a prolonged, jagged rocky ridge, approach a series of ridge walls of the second rock tower. The exit to the second rock tower is simpler on the right side.
Further — exit onto the ridge. The ridge is jagged, made of dense rocks, but not complex to pass, and is traversed simultaneously. It leads under the rock tower of the pre-summit.
Route key: The exit onto the rock tower of the pre-summit is the key place on the route. Dense, steep rocks with an abundance of holds and footholds but with a minimum of places for organizing intermediate belays.
After passing the key place and exiting onto the pre-summit, and then onto the western ridge, the route is not complex. Along snowy-talus fields, approach under the summit talus dome. Further along simple rocks of 1–2 complexity categories and large-block talus, ascend to the summit.
The summit is well-defined. On the summit — a triangulation mark.
Equipment: for a sports group of people: main rope 2 pcs × 10 mm × 50 m. Rock pitons — 10 pcs. Chocks — 12 pcs.: small stoppers — 16, "Parus" stoppers — 6, hexes — 4.

For the Instructor's Attention
- The route meets the requirements for training-sporting routes of 3 cat. diff. Rocks on the route are dense, monolithic. Rockfall hazard — subjective, dependent on the participants themselves.
