After pressing Start on the title screen, the game's camera swings through a cabin window to reach the main menu inside. Hanging above the window before being obscured by menu borders is a poster featuring the "devil" logo from Wave Race: Blue Storm, a game which shares characters with and takes place in the same universe as 1080° Avalanche and its predecessor 1080° Snowboarding.

It's possible to make the game appear pixelated by using a cheat code. This can be done while using the Old School Board, pausing the game and pressing Up, Down, Up, Down, Left, Right, Left, Right, B and unpausing the game.

A special board called "Old School" looks like a NES controller and makes the small Mario jump noise when you jump, and the 'bump' sound effect when you land.

A Mario ice statue appears near the end of the "Angle Light: Midnight City" course.

A Mario sprite from Super Mario All-Stars appears on the bottom of Ricky Winterborn's unlockable "8-bit Soul" snowboard. The alternate version of this board has Luigi on it.

The game's original title was 1080° White Storm, similar to Wave Race: Blue Storm. This can be seen in the game's files, where an unused placeholder title screen can be found.
