Calamity Cliffs is complete with many of its own dangers and is also part of the key to ultimate velocity. It's extremely dangerous, though it is possible to survive it with some intelligence.
In Sonic Christmas Blast, Santa Claus shows Sonic and Tails to the cliffs to complete the second challenge to use the Ring of Ultimate Velocity, which is to snowboard down the cliffs. Sonic, while snowboarding down the cliffs, spotted a trap by Scratch and Grounder. To avoid the trap, Sonic skid his snowboard and covered the duo in snow, setting off the giant bear trap.
