The Observatory contains state-of-the-art interpretive displays that magically reproduce the sequence of geologic events that transformed the landscape and opened up a new era in the science of monitoring an active volcano and forecasting eruptions. Visitors can read amazing eyewitness accounts from eruption survivors.
Leave the observatory and take the half mile walk on the “Eruption Trail”. Visitors will see the lava dome, crater, pumice plain, and the landslide deposit.
