There is a winding path that comes from this cave and down into the Taiga entrance. This path is slippery and objects on it will slide downwards no matter how much friction is applied.
The Taiga boulders that fill and block the entrance to the Taiga are summoned from the cave's interior. After being blown up, they will refill the entrance.
During the Roblox's "Winter Games 2017" Event, the Snow Cave did not produce any boulders, which removed the usage of the Taiga Scaffold. It should be noted that the boulders did not spawn even after the event. The scaffold was at the entrance to the taiga.
