Pano pane zvakakosha zvebasa reGomo reSt. Helens mumakore ekupedzisira 2000:
Goi Rocks Eruptive Period
Inenge 1800 AD
Iyi nguva inoputika yakagara makore 100-150. Zviitiko zvinozivikanwa zvinosanganisira kuputika kwemhepo muna 1842, iyo yakateverwa ne extrusion yeGoat Rocks dome. Nhoroondo dzemazuva ano dzinoratidzira basa kakawanda muma1840 na1850, asi hazvisi izvo uye zvinopesana.

Iyi nguva inoputika yaisanganisira maviri ejections makuru emadota, uyewo maruva anoyerera uye kuvaka dome.
Sugar Bowl Eruptive Period
Inenge 800 AD
Gomo reSt. Helens rakagadziriswa nekubatanidzwa kwekuvaka dome, kuwedzera kwekupedzisira, uye kuputika kwemhepo panguva iyi yekupisa kwemhepo.
