What You Need to Know Before Summiting the Notorious Mount St. Helens
Mount St. Helens is located in Skamania County, southwest of Washington. It lies in the Cascade Range and is among the top 5 notorious volcanoes among the Ring of Fire (the Cascade Volcanic Arc). It is approximately 80km northeast of Portland in Oregon.
Mount St. Helens is an active stratovolcano consisting of lava combined with pumice, ash and other rock deposits. It is only 40,000 years old. Streams that flow from this mountain enter into three rivers namely the Toutle River, the Kalama River and the Lewis River.
Geology and eruption
Mount St. Helens is famous for its explosive eruption that occurred in 1980 which was recorded as the most economically destructive and fatal volcanic incident in the history of the United States of America. 57 people lost their lives, 250 homes and 47 bridges were destroyed. Additionally, 24km of railways and 298km of the road were affected and destroyed.
An earthquake that measured 5.1 on the Richter Scale triggered a massive avalanche of debris causing the eruption. The blast emitted at a high-velocity super-heated gas, ash, and rock which had a temperature of about 350 °C moving at a speed of almost 500km per hour. Mudflows and pyroclastic flow followed soon afterward. There was complete darkness in Spokane which is located about 400km from the volcano.
Mount St. Helens Volcanic eruption
The northern face of the mountain collapsed and mixed with snow and water to form lahars that destroyed bridges and vegetation. It has continually experienced nearly 130 small tremors and a frequency of about 40 localized earthquakes in a week. The sleeping giant is predicted to awake at some point but not in the near future.
The mountain summit was reduced to an elevation of 2,549m from 2,950m. What was left as an aftermath was a horseshoe-shaped crater of about 1.6km wide? The small successive eruptions have resulted in the formation of magma dome on the southern side.
Mount St. Helens Climate
Mount St. Helens experiences a warm and temperate type of climate. The winter has more rainfall than in the summer. The average annual precipitation is 1146mm.
The average temperature in a year is 11.4 °C.

You will hike through a forest trail for the 2.1 miles. At the LowestTrail, you can use the toilet on your right-hand side. Follow a rocky ridge marked by wooden posts till the last post. Proceed with that ridge and soon enough you will be at the summit. If you are climbing during winter, trekking poles and an ice-axe will definitely come in handy.
It is the single most direct route to the crater rim and mostly used during winter and spring. Mount St. Helens has great summit view and experienced hikers can enjoy a non-technical climb and begin at Marble Mountain Sno-Park and cross to Swift Creek. At about 2 miles in, you will come across the breathtaking Chocolate Falls that are along Swift Creek that will open up to a barren landscape full of mudflows and rock towards the crater rim. Head west to find the true summit.

Flora and Fauna on Mount St. Helens
36 years after the eruption of Mount St. Helens, vegetation has tried to claim its roots back. There is evidence of pre-forest conditions and young patches of the deciduous forest can be seen.
You can also see, dense thickets of shrubs, colorful flowers in their complexities, paintbrush, lupin and scattered conifers are evidenced too.
The black-tailed deer, the mountain goat, cougar, the American Black Bear and the majestic elk were the famous five animals that existed before the eruption. They all perished as they could not outrun the pyroclastic flows and survive the poisonous sulfur dioxide gas that was emitted with the ash. But all the five species are now back in the zone.
Other animals present include the Western frog, the American beaver, bird species like the yellow warbler and the willow flycatcher.
Hiking with Kids
Children above the age of 10 years can climb the mountain to the summit. Keen observation, proper gear and guidance are essential when hiking with kids.
