The given features are describing a geographical phenomenon that is hazardous to skiers and mountaineers and involves the movement of snow and ice down a steep mountain side. Let`s analyze each option to identify which phenomenon matches these features.

Option 1: Slump and earthflow - Slump is a type of mass movement in which a section of soil or rock moves downhill, while earthflow is a slower form of mass movement involving saturated soil. Neither of these options involve snow and ice, so they do not match the given features.

Option 2: Avalanche - This option matches all the given features. An avalanche is a rapid flow of snow and ice down a mountain slope, and it is indeed hazardous to skiers and mountaineers. The mix of falling, rolling, sliding, and flowing of materials also describes the movement of snow and ice during an avalanche.

Option 3: Landslide - A landslide involves the movement of soil, rocks, or debris down a slope, which does not match the given features of snow and ice.

Option 4: Rockslide - A rockslide is the rapid sliding or falling of rocks down a mountain slope, which does not involve snow and ice.

Therefore, the correct answer is option 2: Avalanche.
