Around-the-Bump Line
HOW TO DO IT
Around-the-Bump Line
Routing around bumps uses their pattern to place turns, rather than treating every crest as a mandatory obstacle to cross. Line choice should prepare the next movement.
Preparation and setting
Rounded turns and stop control; a readable manageable bump field.
Execution / practice sequence
- Identify several usable turning spaces.
- Choose a route around selected bumps.
- Initiate the first turn early enough for the next space.
- Use the shape to manage speed.
- Stop before the route exceeds available control.
How to learn / practise
Plan two or three turns, ride them, then compare plan and actual path. Extend the section only after placement is reliable.
Errors and corrections
Looking only at the nearest bump creates late decisions. Forcing the same side around every bump can remove options. Replan instead of rushing.
Observable checks
Turn placement fits the bump pattern and leaves a deliberate exit.
HOW TO DO IT
Around-the-Bump Line
An around-the-bump line routes the board beside selected mounds instead of forcing it over every high point. It can reduce vertical disturbance, but it is not automatically the slowest or easiest route. A deep trough may be narrower, harder or faster than the shoulder beside it. The route must fit the next turn as well as the current gap. Line choice determines where direction changes are possible. If the rider waits until the board reaches a narrow gap before starting the turn, there may be insufficient space for the board to rotate. Starting the shaping earlier can place the board across the slope before the corridor constricts. Skidding is often a useful part of that shaping; a carved trace is not the required outcome.
Preparation and setting
Required: linked skidded turns on comparable smooth pitch, a controlled bump traverse, and the ability to interrupt the sequence at a visible stopping place. Start at the edge of a small bump field with an easy return to groomed snow. Inspect hard troughs and traffic independently of the apparent size of the bumps.
Execution and learning sequence
- Select two turns and an exit. Identify the spaces where the board can actually change direction.
- Choose which side of the first mound leaves room for the second turn; avoid choosing purely by the shortest route.
- Set speed before entering. Release the previous edge early enough to guide the board into the first space.
- Shape the turn beside the mound, using a manageable skid where necessary to regulate pace.
- Finish with the board aimed toward the next usable space rather than the bottom of the run.
- Complete the second turn and exit as planned. If placement is lost, use the rehearsed stopping option rather than improvising a faster line.
Progression and transfer
Practice the two-turn route several times only while the surface remains comparable. Change one turning space and repeat the planning process. Later add a third turn. A good result includes the ability to describe why a route was rejected; it is not just a longer uninterrupted descent.
Mastery and links
plan and ride more than one workable short route, including an exit. Continue to AMTA-05 and 07.
Diagnostic hypotheses and rechecks
Possible causes are hypotheses to test, not diagnoses inferred from one attempt.
| Observation | Possible cause | Diagnostic exercise | Correction | Recheck |
|---|---|---|---|---|
| Second turn has no room | First exit aims too directly downhill | AD03 with exit landmark | Finish the first turn toward the next space | Second release begins before constriction |
| Board accelerates along a trough | Selected route too direct or trough too steep | Inspect alternate shoulder line | Choose a rounder route or leave the section | Pace remains controllable after both turns |
| Every mound triggers a hard tail throw | Late planning or missing short-turn control | Repeat one turn on adjacent smooth snow | Restore controlled steering, then shorten sequence | Heading changes are intentional rather than reactive |
