Kilkukrotnie wspomina termin "push", który podaje za wydaną w 1908 r. ksiażką Shostakovicha:

1. Fragment o zejściu pod lód:

The ice-hole is cleared, the way down is free. If the purpose of diving is to admire the ice from under the water, the hole is usually made close to a “push”. Here’s how V. B. Shostakovich describes it in the article. “In their final state pushes are represented by slits, the edges of the slits are pressed against each other.

2. Fragment o powstawaniu "push:"

Scientists explain the formation of “pushes” by thermal expansion of ice. It turns out that the night and day temperature difference at 20 degrees (and it is common for Lake Baikal) expands one kilometer of ice for nearly half a meter! And can you think about 10 or 20 km?
Push formation is accompanied by a bang and crash comparable to the noise of a cannonade.

3.
Every dive brought new shots of unusual ice formations. Ice caves, grottos and tunnels formed by a push.
