Ski cut triggered slide. E Face Red Lake Peak

Made a ski cut on the furthest skiers right gully on the E side of RLP.  Slide started as a couple of large pinwheels and upon hitting the convex rollover gained momentum.  I'd call it D1.5 as it was not large enough to bury a person but could have potentially taken a skier off course. Debris carried a bit of speed and force after a very slow start, running roughly 400 vertical feet down the gully. No immediate threat as the cut was made into more moderate terrain on the prow of the gully which was holding more consolidated snow.
