Cardboard Leonardo's last masterpiece

Yesterday, while descending into the Bolshoy Buzluk ice cave, Konrad Zyuskov's famous cardboard camera was tragically lost. Being almost at the very bottom of the accessible part of the cave, Conrad installed the camera on an ice block and opened the lens. The shot promised to be amazing. But suddenly, out of nowhere, a gust of wind knocked over a light cardboard camera and it smoothly slid down in front of the stunned owner’s eyes. Everyone gasped... :) The drama of the situation lay in the fact that the unique camera did not immediately fall into the abyss, it got stuck on a wide ice step a few meters from the hole.
What's dramatic about this?
The owner wanted to save his brainchild! Conrad climbed onto the ice. I yelled at him, but it was too late - his boots had already stepped on the slippery surface of the icy influx...
Fortunately, he immediately felt how unsteady his legs were and curbed his ardor. Conrad realized that without special equipment he couldn’t take a single step here. There was one more way to get a camera - a remote one. For half an hour we tried using sticks, stones and ice fragments to push him off the step to the side. But it was all in vain, the camera did not want to leave its habitable place. But it was time for us to leave. With a heavy heart, Conrad turned around and walked towards the exit. And his cardboard masterpiece remained lying in the middle of the icy bulk of Bolshoy Buzluk. Its lens is still open and continues to catch the rare rays of the Sun in the darkness of the cave bottom.
