We can't see weak layers in the snowpack unless we take a minute, get our shovels out, and investigate... but the snowpack has an amazing memory and doesn't forget where these deficits are located. All we need to do is find one inconsistency (such a shallow, rocky section of the slope like in the image above), collapse the pack, and now we're staring down the barrel of a dangerous avalanche.
Most terrain offers a deep snowpack and it's happy in its own skin. Now I need to think about suspect terrain I want to avoid, and that includes steep, rocky terrain and slopes that avalanched near the ground earlier in the season. Recent avalanche activity involving weak snowpack structure confirms this hypothesis.
