On May 18th, 1980, thirty years ago today, at 8:32 a.m., the ground shook beneath Mount St. Helens in Washington state as a magnitude 5.1 earthquake struck, setting off one of the largest landslides in recorded history - the entire north slope of the volcano slid away. As the land moved, it exposed the superheated core of the volcano setting off gigantic explosions and eruptions of steam, ash and rock debris. The blast was heard hundreds of miles away, the pressure wave flattened entire forests, the heat melted glaciers and set off destructive mudflows, and 57 people lost their lives. The erupting ash column shot up 80,000 feet into the atmosphere for over 10 hours, depositing ash across Eastern Washington and 10 other states. Collected here are photos of the volcano and its fateful 1980 eruption. -- The Big Picture
The finest, clearest days in Seattle are those when the inhabitants remark, "The Mountain is out." The Mountain is Mount Rainier, a peak so looming and solitary on the edge of the Puget Sound basin that it makes its own weather. Here's a peek at the mountain I took last week from I-5 inside Seattle city limits.
Continued...I heard they exploded,
The underground blast,
What they say's gonna happen,
Gonna happen at last,
That's the way it appears.
They tell me the fault line
Runs right through here.

PERHAPS GEOGRAPHY IS DESTINY AFTER ALL, as the subtext for this otherwise bland caption for a startling image indicates:
The Sinai Peninsula, located between Africa and Asia, is a result of those two continents pulling apart from each other. Earth's crust is cracking, stretching, and lowering along the two northern branches of the Red Sea, namely the Gulf of Suez, seen here on the west (left), and the Gulf of Aqaba, seen to the east (right).-- From NASA's Shuttle Radar Topography Mission

Unnamed Lake
"The refuge is so remote and untamed that many peaks, valleys, and lakes are still without names and shall remain that way. Marsh fleabane cluster along the lakeshore, while Nichenthraw Mountain and spruce trees are reflected on the calm water of early morning."

Geology of the Conterminous United States at 1:2,500,000 Scale
The present Geologic Map of the United States follows the same format as the preceding Geologic Map of the United States of 1932. Ideally, both have been designed to represent the geological features that the user could find if he should visit any locality within its limits, that is, the bedrock formations that lie at the surface at that locality. In many parts of the country, especially in the arid regions of the Southwest, this is literally true. In other parts of the country there are lesser or greater departures from this ideal, owing mainly to concealment of the bedrock by surficial material.
James M. Clash's Forbes article Namibian Giant, is not about some future draftee for the Celtics. It's a fascinating item about taking on a pile of sand so vast it can hardly be imagined.
Wait 30 million years and you get Big Daddy, one of the oldest sand dunes on the planet and thought to be the biggest. A ziggurat of red sand, Big Daddy rises 1,200 feet from the parched African earth of the Namib Desert. Above is the deepest of blue desert skies; at its base is a sea of golden, talc-like clay. The sharp contrast of the three colors reminds one of a giant Rothko painting.Climbing Big Daddy, however, is not like climbing a Rothko, which would be a great deal easier. First you've got to get yourself to Namibia, in southwest Africa, sandwiched between Angola and South Africa. We flew 15 hours nonstop from New York to Johannesburg, connecting there to a two-hour flight to Windhoek, Namibia's capital. From Windhoek it's still another hour in a small charter plane to Sossusvlei, but the ride, with the sea of dunes undulating below, is supernaturally beautiful.
