ICE MARATHON Clean Water Preservation Run

Ice scouting

1st ice scouting trip for the16th Baikal Ice Marathon - Clean Water Preservation Run

Companies that supported their  Russian runners in the XVI edition of BIM: 


As we previously , on the 2020 Year eve, informed you, Lake Baikal was frozen in its northern and middle parts by December 26, 2019  . As usual, it took some more time then when  Lake Baikal started gradually freezing over in its southern part. By January 08, 2020,  southern  part of lake Baikal still  had huge open water areas with lots of ice fields floating, drifted  with wind and underwater currents. However,  in spite of  2019  warmer autumn ambient  temperatures  compared to the last year Lake Baikal completely froze over on the night of January 12, 2020 which is a week earlier than last year.  In 2019 Lake Baikal froze over  in its  southern part  on January 12 but strong  “verkhovik” north-eastern wind, unleashed by Baikal within the night of January 13, 2019,  broke up the just formed ice allowing it another week to steadily refreeze again. This year the “verkhovik” wind did not happen to blow  which made it possible for  the ice cover of the lake to consolidate  and, remaining firm, continue its growing and thickening.  

Last Saturday , on  Jan. 18, 2020, BIM team made the 1st ice scouting trip in the area  of future 16th BIM ice running course. The distance scouted was within the area of 12 km from Listvyanka ( western shore) into the open frozen sea.   Average ice thickness on the scouting traverse  was   about  seven  inches (  18 cm). The ice scouting made it clear that, at least, last 6-7 km loop of the future BIM run course will definitely have different  coordinates compared to the last year’s one . Due to the ice pressure ridge  that this year settled down further south than last year, the ice hummocks likewise are currently located at other spot. We will have to avoid them and  find the loop for proper route which has to be both safe/ best comfortable for running   and within total distance of 42 km frame.  The ice surface as one can see from the video below until the 12 km distance from the western shore ( not counting the above indicated ice pressure ridge area) is, at time of the ice scouting, mostly not covered by snow layer.

The ice cover by the eastern shore of Lake Baikal , near Tanhoy, (not yet scouted by us) is seen and reported  to have the 4 to 6 inches snow cover on ice. However, the situation is always likely to change. Man supposes, Baikal disposes. 

See the video with Baikal cover of week fresh ice made by the BIM team and the 1st runner of 2020 ice frozen Baikal.

Another video features the winter voice of Lake Baikal. Remember in the BIM Rules: “Do not get frightened during the run on ice course once huge rumble can sound from ahead and  the ice can shake  under foot. This is a usual phenomenon of the internal ice cracks formation, and it will not cause any wide ice opening.  Such huge rumbles & thundering like distant cannon fire, called by locals  "Baikal  symphony", can occur near  ice pressure cracks as well as the ice shaking and rumbling can also be caused by the Earth tremors which in the seismic area of lake Baikal are very  usual – “mantle plumes of the Mother-Earth are very near here...”


Live Baikal Starts Freezing in 2019

On the eve of New Year of 2020 we share with you  our brief BIM  video-newsletter of Lake Baikal freezing start in this December. See live and magic Baikal breath saturating its waters with oxygen before putting an ice blanket on  its huge body, as well as the freshwater seals and  nature  ice cycle fun production.

Ice Scouting Reports in 2018

On February,15, 2018 the 3rd BIM ice scouting trip by hovercraft made it possible to find the passage through the  huge field of blizzard snow dunes that hide beneath lots of refrozen  broken, cobblestone ice and large grain ice  with needle like blades on the surface.

Due to strong north-western wind blowing for a few days,  the newly formed ice in the area of BIM had been twice broken and ripped apart. After refreezing,  it fromed a huge filed of big cobblestone and wind scalooped ice that now stretches  for over 8 km long/2 km wide (17 km away from the western lakeshore). 

The hummocks of the ice pressure ridge in the area of BIM were nearly at same place as last year, and we could monitor it quite well to adjust future BIM ice course in its conditions. But the pancake and cobblestone ice fields were hidden under the snow dunes created by blizzard, making it impossible to plot the safe and more comfortable for running ice course, unless we can find the passage through it. If we have failed to locate such a passage, we would have to cut off the cobblestone and pancake ice cover by armored track-laying vehicle, or manually. Anyway, too much  of fantastic work could await us!   


The satellite photos of the ice covered area of Lake Baikal showed unusually long ( over 200 km) ice pressure ridge, stretching from the area of eastern shore of  Olkhon Island, all way to the southern tip of Lake Baikal, parallel to its shore ( #1).  The usual “cape-to-cape” ice pressure ridge in the area of BIM ridge ( #2) , merges into the #1 ice ridge , contunuing further to # 4 destination. Numbered as three above is that huge snow duned cobblestone and slush balled field.  

The two  ice scouting trips by 4WD vehicle (tires wrapped with chains) were not successful, no any passage through was found, two tires were seriously punctured.

On February, 15, on a nice sunny weather,  we started out by hovercraft from Listvyanka across the lake in search of the passage. It was  found quite unexpectedly after a number of long shuttle, run about rides. Alongside passage search,  we carried on measuring of ice thickness all the way using  cordless hammer drill with Russian made single oversized carbide bit.  It’s was easy sledding to drill the ice with this “Praktika-Profi” bit ,  better than any other, goes with a swing !   (twice less expensive than similar Japanese one; see the photo).

The working length of the drill bit we used is 55 cm, in all our measuring drills of the ice, the bit went completely into the ice, but did not reach the water. This allows us to claim that average thickness of ice en route  the BIM run course is over 55 cm. Even at the eastern shore, where ice is usually not that thick as near the western one, this year it was same thick. In some places, the ice was over 65 cm thick.

Next week we will continue ice scouting work and lay GPS coordinates for possible  BIM run course  (we need to have two options in case earthquake  or weather “day-night” temperature fluctuations cause changes in the ice pressure ridges, or fresh cracks appear as living Lake Baikal breathes, opening up its water to enrich them with oxygen.  

Below, see some images from this ice scouting trip.


Above and below. Oufflow of the Angara river from Lake Baikal ( the Lake's only outlet and the widest river source in Eurasia). The Angara's outflow never freezes in winter: due to very fast current ( steep river bed gradient) it takes the water of lake Baikal after entering the Angara's river bed about 10 km to cool down and be able to freeze over its suraface. Below, on the right, across the river's exit , there's a small town of Port Baikal from where famous historical RoundBaikal railway begins. 






Report # 1 of January 17, 2018

By January 04,2018 Lake Baikal  froze over in its northern part, but thickness of ice allowed only lightweight snowmobiles to ride on the frozen water surface not far from the shoreline.

In the middle of Lake Baikal, in the area of Maloye Morye (so-called Smaller Sea-   section of the lake enclosed by the western shore of Olkhon Island and western mainland bank of Lake Baikal), the ice formed on January 06, and grew  on January, 07, 2018 by 15 cm. Interesting to note, that the first week of the new year was marked by three earthquakes in Lake Baikal central depression ( Jan.01 – 3.1 on the Richter scale , Jan. 2 – 4 on the scale, followed by 3.4 on January 07). In spite of the earthquakes, one of which occurred near Olkhon Island, Lake Baikal froze over in the Maloye Morye, and the ice did not break down. However, one-meter wide crack appeared near Ogoy Island.

 As for the southern part of Lake Baikal , in the area of future BIM run course to be laid between the two opposite banks of the lake, the water of Baikal, first, froze over on January,13 ( see the photos below), but the wind from the Angara river ( the one which usually “meets”  the BIM finishers near the 30th km mark of the run course) broke down the fresh ice surface into huge  ice floes of 200 meter and more in diameter and scattered  them.  This time  the Angara wind blew strong breaking  down just formed ice and  then coiling the ice and snow in a unique aerial ‘tornado’ shaped, whirling masses, both near Listvyanka and opposite it, in Tanhoy  (possible BIM finish or start lines), as it is seen on a satellite photo below.

Today Lake Baikal surface refroze again. If the ‘verkhovik” higher wind or the Angara wind will not blow the next night, Lake Baikal can remain frozen over its entire area. The upcoming usual frosts on Epiphany celebration, expected in two days, will then facilitate growing of ice cover of the Great Baikal. If this happens, then by the end of next week we may be able to go on the first ice-scouting trip. However, as they say, man supposes and Baikal disposes.

We will keep you all further informed about details associated with the preparation to 14th edition of Baikal Ice Marathon “For preservation of clean water”.
