Kolpanskoye Lake near St. Petersburg. Origin hypothesis

A hypothesis is formulated about the formation of Kolpanskoye Lake, located in the vicinity of the city of Gatchina (near St. Petersburg, Russia) as a result of a meteorite fall. An approximate calculation of meteorite characteristics was performed using the energy model of the meteorite/ground dynamic system and nonlinear programming methods. The obtained preliminary data can be used in further research.
