Mt. St. Helens National Volcanic Monument

Mt. St. Helens National Volcanic Monument was established by Congress in 1982 to protect natural features and processes and provide access for recreation, research and education. The monument has become an internationally renowned laboratory for the study of earth processes and ecosystem recovey following large-scale disturbance. Access to the area north of the volcano is restricted to allow natural processes to proceed unimpeded and protect scientific research.
You may remember where you where when Mt. St. Helens erupted but until you visit the site, you can not comprehend the magnitude of the blast. Most of the words in this post are from the Volcano Review, a park visitor guide. The mountain lost 1300' of height and 0.67 cubic miles of total volume.

Here's what Mt. St. Helens looked like before May 18, 1980.

The following is a sequence of photos as the eruption occured. Starting in March of 1980 there were lots of earthquakes under the volcano and a small vent formed.

At 8:32 a.m. the north face of the mountain began to slide downhill.

The eruption began with a massive landslide (debris avalanche) that buried 14 miles of river valley to an average depth of 150'.

The landslide released trapped magma and gas, producing a sideways explosion (lateral blast) of hot rocks and ash killing trees up to 17 miles north of the volcano.

The eruption leveled 230 square miles of forest in less than 10 minutes.

A vertial ash eruption rose to a height of 15 miles above the crater and continued for 9 hours. Ash drifted to the northeast.

Cement-like slurries of glacial melt water and boulders called lahars scoured and buried streams draining the volcano. Fiery avalanches of pumice and hot gasses called pyroclastic flows flowed into the valley north of the crater.

Fifty-seven people died because of the eruption. One of the most memorable was a man called Harry R. Truman who had a lodge on Spirit Lake. He refused to leave and stayed with his 16 cats. He did not survive. Others were NFS volcano watchers or people not in the restricted area around the volcano. The mudflows down the river valleys swept away homes.

The massive landslide that triggered the eruption buried 14 miles of river valley and created 150 new lakes, ponds and wetlands. This new habitat has powered a rapid resurgence of life - creating the most biologically-rich landscape in the monument. It is home to a diverse array of amphibians, birds, insects and at least 140 plant species.

Predators such as hawks, owls, coyotes, bobcats and weasels search the 230 square mile blast area for small mammals. Small mammals play a vital role in ecosystem recovery by feeding on plants, creating burrows, dispersing seeds and concentrating nutrients in their droppings.

Fish populations rapidly rebounded in steep mountain streams that were smothered by volcanic ash. Rapidly flowing water flushed ash from channels exposing cobbles and gravels that are important for spawning and aquatic insects -- a primary food source. Fish have also benefited from pools and riffles formed by blown-down trees and pleantiful food in the open sunny, blast area.

Large herbivores like elk and deer are modifying plant communities around the volcano. By selectively and heavily over browsing some plant species verses others, and through their trampling and ground disturbance, elk are profoundly influencing plant succession at Mount St. Helens.

This is the Blast Zone.

Although the blast area is untouched by humans as an experiment to see how nature recovers on its own, much of the rest of the land affected by the eruption was owned and used by lumber companies.

One ridge where the trees on the south side were blown over and the trees on the north side were killed by the hot air. The trees closer to the eruption were snapped from their trunks and became part of the debris carried in the lateral blast.

We found this little fellow along a trail. He sat about 5' from us and calmly ate his flower. The only other wildlife we saw was a snake on a different trail.

The stumps left after the blast.

Noble fir that were planted after the blast. I just thought they looked like an oil painting.

Wenatchee to Mossyrock

Our first stop on the third day of our trip was Liberty Orchards in Cashmere, WA. They make candy and have tours.

The tour was real short and started in the baking room where they were making Aplets. This is an apple candy. First it is poured out into pans about 3/4" deep.

After cooling the candy sheets are ran through this machine where it is cut into pieces and then rolled in powdered sugar before falling into a tub.
The tubs are put in front of people that pack the candies into the boxes.

A gal at the end was putting on the box tops.

Each box was inspected before being put into packing boxes.

Here Nolan models the hair nets we had to wear while on the tour.

We wandered around the gift shop/store where I found what I wanted. But they were kinda pricy so I left them on the shelve.

The box of pecan carmel clusters that Nolan wanted cost $20 so he was greatly disappointed.

Next we headed south on Hwy 97. It runs though the Wenatchee National Forest so there was plenty of green and nice curvy roads.

At Ellensburg we got on I-90 for a short distance before getting on SR 821 which runs through a canyon down to Yakima. In this photo you can see I-82 which parallels SR 821.

Along SR 821 we found some hop fields.

After Wenatchee we got on Hwy 12 and headed west. They had to hold back the rocks at this spot.

This is the upper falls.

And the lower falls.

Saw these interesting flowers at this stop but I haven't identified them yet.
This one is further open.

An information panel told us a story

What we were supposed to look at...

What we could really see. It was raining so visibility was terrible.

A vertical stream across the canyon.

Where Clear Creek goes after the falls.

Look at the rock pile at the bottom of the cliff. They look flat like they are slate but I don't know what they are.

At this viewpoint it was raining hard so we didn't even get out of the car.

Got photos anyway. We'll have to go back when the weather is nicer.
