The material produced by the eruptions of Mount St. Helens have varied over time, but the eruptions of recent decades, including the 1980 eruption, have involved dacite magma, whish is of intermediate-felsic composition. The famous 1980 eruption produced ash and pumice rather than lava.

Does Mount St Helens spew pahoehoe pillow Aa or Blocky lava?
Mount St Helens produces blocky lava.
What kind mountain is mount st Helens?
Mount St. Helens consists of lava rock interlayered with ash, pumice and deposits, together with layers of basalt and andesite.
Is mount st Helens high in silica or low in silica?
Mount St Helens produces mostly dacite lava, which is relatively high in silica.
Was There any lava flow at Mt St Helens?
Yes, there was a significant lava flow during the eruption of Mount St. Helens in 1980. The eruption caused the collapse of the volcano's summit, leading to a massive explosion and the release of a pyroclastic flow. This flow melted the ice and snow on the volcano, mixing with ash and rock fragments to create a fast-moving lava flow known as a lahar.
How did the people die of mount st Helens?
Mount St Helens was an active volcano..... put 2 and 2 together. Lava and Humans dont mix very well!
Does Mount St Helens lava flow violently or quietly?
Lava can't flow violently. Highly explosive eruptions such as the 1980 eruption of Mount St. Helens do not produce lava flows: they produce clouds of ash, gas, and pumice. Mount St. Helens has produced "quiet" lava flows at times.
Does Mount St Helens spew pahoehoe pillow Aa or Blocky lava?
Mount St Helens produces blocky lava.
What kind mountain is mount st Helens?
Mount St. Helens consists of lava rock interlayered with ash, pumice and deposits, together with layers of basalt and andesite.
Is Mt St Helens a lava dome?
No. Mount St. Helens is a stratovolcano. There is a lava dome in the crater.
What is mount st helens made out of?
alternating layers of lava and tephra

by ash, rock, lava, and gas

On Mount Saint Helens the hot lava melted the snow and caused a?
On Mount Saint Helens, the hot lava melted the snow and ice, and it caused surges of water that eroded and this mixed with loose rock debris. This created volcanic mudflows or lahars.
What type of rock layer does mount st helens have?
As Mount St. Helens is a volcano the slopes would be covered in layers of volcanic dust and lava.
What type of volcanic rock or lava fragments come out of mt Saint Helens?
As with many stratovolcanoes, the type of activity at Mount St Helens varies. In its famous 1980 eruption it produce massive clouds of ash and pumice and later built a lava dome. The rock formed was dacite. However, other material has erupted in the volcano's past, including basaltic lava flows.
