ASC Risk Assessment & Mitigation 3

Question 1

What does the Extended Column Test (ECT) measure that the Rutschblock test does NOT specifically isolate?

Accepted Answer

Crack propagation potential across a weak layer

Answer

The ECT assesses both initiation and propagation of fractures, giving information about whether a failure in a weak layer will spread across a slope.

Question 2

A slope with a 38-degree angle on a north-facing aspect three days after a storm represents elevated risk primarily because:

Accepted Answer

Cold temperatures slow settling and sintering, preserving instability

Answer

North-facing slopes stay cold, which inhibits the settling and bonding that stabilize new snow, keeping instability elevated longer than on solar aspects.

Question 3

Which rescue tool combination is considered the minimum standard kit for backcountry travel in avalanche terrain?

Accepted Answer

Avalanche beacon, probe, and shovel

Answer

Beacon, probe, and shovel form the essential triad for companion rescue—the beacon locates, the probe pinpoints, and the shovel excavates the buried victim.

Question 4

A terrain trap is best described as:

Accepted Answer

A feature that increases burial depth or injury severity if an avalanche occurs

Answer

Terrain traps—such as cliffs, gullies, and trees below a slope—amplify the consequences of even a small avalanche by increasing burial depth or trauma risk.

Question 5

When using the North American Public Avalanche Danger Scale, what does a rating of 'Considerable' (Level 3) indicate about triggering?

Accepted Answer

Human triggering is likely on many steep slopes

Answer

At Considerable (Level 3), human triggering is likely on steep slopes, making careful route planning and terrain avoidance essential.
