  5. When did Lassen Volcanic become a national park? The work to create the national park started In 1906 when Theodore Roosevelt was president and finished in 1916 when Woodrow Wilson was president. It was the eruption of Lassen peak that finally generated enough interest to make it a national park.

  6. How was it formed The park was formed by Lassen Peak when it erupted in 1915. This blast traveled many miles till it stopped and cooled. Then from the lava more Volcano’s took form. They used to be just one now there is many.

  7. Types of rocks “1) hybrid black dacite lava containing (2) undercooled andesitic inclusions, (3) compositionally banded pumice with dark andesite and light dacite bands, and (4) unbanded light dacite.”
