Emotions Run High

This was a very special and emotion packed day. We were headed to Mt. St Helens and, finally, the sun was out. Even the few clouds in the area gave way. As we approached the blast area, the signs began to read “monument”. This entire area is not a state park or national forest any more. In fact, more than 27 years later much of the area is still buried under many feet of ash, pumice and mud. We arrived at Johnston Ridge Observatory which is approximately five miles from the mountain. The ridge got it’s name from a vulcanologist named David Johnston who was checking instruments on the morning of May 18, 1980 when the entire side of the mountain was jarred loose by a 5.1 magnitude earthquake which triggered the ultimate eruption. He died just seconds after alerting Vancouver about the eruption. From the Observatory, we looked directly into the horseshoe shaped crater formed by the blast. A new lava dome called “the Bulge” is forming and scientists believe this new dome may eventually replace the more than 2,000 vertical feet that was dislodged with the blast. The area before us was almost completely devoid of life. Not a single tree remained. Behind us was evidence of what was once a lush old growth forest that spread out over rugged terrain for more than 17 miles; all gone in seconds. The trees were either incinerated, uprooted or flattened by the pyroclastic flow. Huge stumps and pieces of two foot diameter logs still remain. It was truly an awe inspiring landscape. David Johnston wasn’t the only person to loose his life that day. In all, twenty two people were lost. It could have been much worse. A light plume of steam came from the top of the bulge; evidence that St Helens is still uneasy and should be respected. Click here for an up to date web cam image taken from Johnston Ridge.
