An asphalt lake (also asphalt pit , asphalt pond or Pechsee ) is a natural occurrence of asphalt .

Emergence

If heavy, viscous and tar-like petroleum comes to the surface at an oil well , asphalt cones form. These can reach diameters of up to several hundred meters and heights of up to 30 meters.

If the volatile components evaporate, the asphalt hardens. Active asphalt oil wells have liquid petroleum under the hard asphalt layer. If such a source is no longer active, the entire mass solidifies to asphalt.
