Walk the Moonshaft
A first-person 3D reconstruction of Slavek's cave and the buried moonshaft, built from the 1944 journal. Walk the grotto and passages, crawl through the barrel-sized hole and the narrow crack, and stand inside the crescent-shaped shaft.
Click the scene to look around (Esc releases the mouse).
Move: WASD / arrow keys.
Crouch and crawl: hold C, Ctrl or Shift — low passages force you down.
Jump: Space.
Dig: hold the left mouse button to swing the pickaxe — dwarf pines and tunnel rock give way, the moonshaft only sparks.
Weapon: press 1 for the pickaxe, 2 for the submachine gun, 3 for the axe (or use the button).
Shoot: with the gun, hold the left mouse button to fire — the moonshaft throws green sparks and a loud echo, and bats can be shot down.
Talk: press E near Slávek, Jurek, Martin's grave, or inside the moonshaft to hear them speak.
Headlamp: press F or use the button to turn it on and off.
Wire-view and fly mode: press Q — fly with WASD, Space up, C down.
Sound: press M or use the button to mute and unmute.
About this reconstruction
The layout follows the journal: a roomy grotto behind a low cleft, a long level passage with squeezes, a barrel-sized hole, and a chamber facing a glass-smooth, blue-blackish wall framed in white stalagmites and stalactites.
The structure is rendered as a cylinder about 25 meters in diameter with 2-meter-thick walls. A narrow crack with a steep limestone trough leads into the crescent-shaped, nearly vertical shaft behind the front wall.
Dimensions are approximations drawn from the text. Toggle the wire-view to see the whole shaft buried inside the mountain.
