XRP and KWJ are on the money. Last nite I witnessed 2 large whoops develope on a freshly groomed track.
1. As a motorcycle or ATV accelerates the wheel spin displaces dirt until the tires ride on top of the soil.
2. As more and more riders accelerate in the exact same place, the first whoop is born.
3. As more and more riders accelerate in the exact same place, the suspension compresses momentarily on the exit side of the whoop, the rebound raises the weight of the bike up and then gravity starts to bring it back down. When the least amount of weight is on the rear tire, wheel spin begins the next whoop.
4. This cycle continues until a sufficient distance is covered allowing the tires to ride on top of the soil.
If riders would not spin their wheels or lock up their brakes there would be no whoops. This would make the greens happy but making riding kinda like golf.
