Hranice Abyss – Measured Depth and the Unknown Below A 40-second English animated introduction to Hranice Abyss by Still Unfiled.

The film visualises the locally reported 519.5 m measured from the rim: 69.5 m to the water, followed by 450 m underwater. The deeper geophysical estimate is labelled separately. Cave geometry and robot movement are illustrative rather than expedition footage or a surveyed model. The closing line invites imagination and does not report a biological observation.

Original instrumental music and sound effects; no narration.
