- Messier 100 (Wikipedia)
Messier 100 (also known as NGC 4321 or the Mirror Galaxy) is a grand design intermediate spiral galaxy in the southern part of the mildly northern Coma Berenices. It is one of the brightest and largest galaxies in the Virgo Cluster and is approximately 55 million light-years from our galaxy, its diameter being 107,000 light years, and being about 60% as large. It was discovered by Pierre Méchain in 1781 and 29 days later seen again and entered by Charles Messier in his catalogue “of nebulae and star clusters”. It was one of the first spiral galaxies to be discovered, and was listed as one of fourteen spiral nebulae by Lord William Parsons of Rosse in 1850. NGC 4323 and NGC 4328 are satellite galaxies of M100; the former is connected with it by a bridge of luminous matter.
- Mount Saint Helens (summitpost.org)
Even before May 18, 1980 when Mt. St. Helens blew its top sky-high while vaporizing a vast area to its north, it was the smallest of Washington’s 5 volcanoes at 9677 ft (2950 m). The blast removed far more than that 1312 feet from the height of the mountain. It left a mere shell of what had been a beautifully symmetrical cone. The melting of several glaciers contributed to the massive floods. Sliding earth buried wonderful stands of virgin forest and recreational facilities and killed untold wildlife. A beautiful tree-lined lake was dammed to a higher level and filled with heat-stripped logs. Condensed rock vapor was carried on the wind to be deposited up to thousands of miles away. For seven years recreational climbing was banned on Mt. St. Helens. Then in May 1987 it was reopened. Only the south routes are still allowed. Access to the crater is strictly forbidden. On clear mornings I can see the mountain as I drive out of my neighborhood to work. That view is a constant reminder of the power of nature. I have always regretted that I had moved from Vancouver, WA to Juneau, AK only three months before the eruption. I returned two years after the eruption, but I missed out on all the excitement. When the mountain blew its top, a part of me went with it.
