Tenacious Pioneers Regrow a Forest

1. Pumice Plain. The Pumice Plain is one of the most spectacular features of the blast zone. Lying between the crater and Johnston Ridge, the plain was in essence sterilized of life after the lateral eruption in May of 1980. The intense heat of the pyroclastic flows killed everything on the plain. Consequently, plant recolonization has been much slower here than other parts of the Blast Zone.

2. Thirty-three active research studies are taking place on land buried in ash. The Pumice Plain on Mount St. Helens is one of the most unique places on Earth, a 6 square mile landscape that was buried in ash during the mountain’s 1980 eruption, where almost no trace of human influence remains.
