This is a special promo track, called The Leap of Death" for the game "Snow Tails".
Here are the rules for the special promo track:
To clear this particularly dangerous obstacle, sleds must cross the purple line with a speed of at least 5. A sled below this speed takes 1 dent card for each point of speed below 5.
Furthermore, if a sled ends its movement on a crevasse square, the player doesn´t refill his hand (as if colliding with another sled).
Of course, the effects described above can be cumulative.
Example: a player whose sled passes the purple line at speed 3 and ends its move on the crevasse takes 2 dent cards and doesn´t refill his hand. Best of luck for the rest of the race!
Enjoy the leap of death...
