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, which is a concurrent problem that still persists. The scaffold is at the entrance to the taiga.
Since October 1st, 2017, the Taiga boulders have been spawning; however, their collisions have been turned off. Now they serve no purpose and only are there for decorations.
