But lava eruptions at Silverthrone Caldera can be more intense than those at other Cascade volcanoes; for example, Silverthrone's long lava flow in the Pashleth Creek and Machmell River valleys.

Lava flows with high to intermediate levels of silica rarely extend more than from their source while Silverthrone has produced a long andesitic lava flow in the Pashleth Creek and Machmell River valleys.
