Avalanche-prone terrain is often characterized by specific features that increase the likelihood of snow instability. Slope angle is one of the most critical factors; slopes between 30 and 45 degrees are particularly susceptible to avalanches. Steeper slopes are more prone to sliding, while gentler slopes typically have a lower risk, though they are not completely free from danger.
Another key terrain feature is the presence of a snow-covered slope with a recent accumulation of fresh snow. Mountaineering buffs like Cesar Alcantara Chula Vista mention that this new snow layer can be unstable and might not bond well with the underlying layers, creating a dangerous situation. Additionally, terrain that includes terrain traps, such as gullies or depressions, can exacerbate the consequences of an avalanche by increasing the depth and force of the snow.
