Shortly after the lateral blast a second vertical explosion occurred at the summit of the volcano sending a mushroom cloud of ash and gases more than 12 miles into the air.
The cloud of ash darkened the skies causing streetlights to come on as far away as Spokane Wash. more than 300 miles (480 km) away.
Ash continued to erupt for more than nine hours. Ultimately an estimated 540 million tons (490000 kilotons) of ash drifted up to 2200 square miles (5700 square km) settling over seven states.
As the north face was blown apart the heat instantly vaporized glacial ice and snow around the remaining parts of the mountain.

The Bald cypress forest was buried under ocean sediments protected in an oxygen-free environment for more than 50000 years
The forest contains trees so well-preserved that when they are cut they still smell like fresh Cypress sap Raines said.
The stumps of the Cypress trees span an area of at least 0. 5 square miles (1. 3 square kilometers) several miles from the coast of Mobile Ala
and sit about 60 feet (18 meters) below the surface of the Gulf of mexico. Despite its discovery only recently the underwater landscape has just a few years to be explored before wood-burrowing marine animals destroy the ancient forest. 8 of the World's Most Endangered Places Closely guarded secret Raines was talking with a friend who owned a dive shop

#Red cedar Trees Rebounded After Clean Air Act A species of old trees in the Appalachian mountains is growing faster than expected in the wake of clean-air controls implemented decades ago a new study shows.
The research on eastern red cedar trees all between 120 and 500 years old also showed changes in the types of carbon
and sulfur in their tree rings a few years after the Clean Air Act was enacted in 1970.
The first thing that got us interested was how these old trees are doing and what are some of the physiological mechanisms that allow the old trees to stay alive Richard Thomas a biology researcher at the University of West virginia told Livescience.
When we saw all this change in growth and the change in isotopes in the early 1980s the research went into a different direction...
The effects were clear in core samples taken from the trees: sulfur isotopes (variations of an element with a different number of neutrons) pointed to pollution
and carbon isotopes showed that the trees'stomata (the pores that are opened and closed to regulate the exchange of carbon dioxide
Photosynthesis and the growth of the trees also accelerated. Meanwhile sulfur isotopes in the wood of tree rings approached levels not seen since the preindustrial age.
Results from the 1930s the Great depression era were almost identical to the results from post-1980 Thomas said.
The suppressed economy during the Great depression led to reduced fossil fuel emissions Tree rings from the 1930s showed improved tree growth and physiology.
Thomas and his team now aim to broaden their search to more species of trees and a wider geographic area.
In Yosemite national park campgrounds and giant sequoia groves that closed while flames raged nearby have reopened along with many main roads.
In the 1920s they mapped every tree on ten acre plots so we know the sizes
and species of the trees Skinner said. Scrubs and grasses were mapped also extensively so well in fact that researchers today know how dense the vegetation on the forest floor used to be.
In fire-prone areas the big trees that survived the fire have thick bark and high branches that protected them Skinner said.
We have seen tremendous change in the forest it has become much denser with three to four times more trees Skinner said.
what we're finding at the base of the diatom tree are things that are long and tubular much like the tube inside of a paper towel roll said Edward Theriot professor of molecular evolution at The University of Texas at Austin and director of its Texas Natural science
what the tree is telling us. To come to this conclusion the researchers analyzed ribosomal and chloroplast genes of more than 200 diatoms and Bolidomonas (a closely related genus). They wanted to test the prevailing understanding of where certain diatoms fall on the evolutionary tree
and included species used as models in genomic studies and diatoms whose placement in the diatom phylogeny has been problematic or controversial.
Sometimes the best tree from molecular data looks radically different from what morphology tells us to expect Theriot explained.
With Ranger we can redirect our time away from just finding the best tree for a dataset towards asking how different that best tree is from
Using a statistical comparative approach the researchers arrived at a different tree of diatom evolution than traditionally conceived and a different point of origin.
which grows on a cacao tree. The tree needs just the right weather conditions to produce the cacao pods.
Cacao trees grow best in the shade. A constant temperature of 77 degrees F is ideal for the production of cocoa beans.
Rainfall is another factor that determines how well the trees produce the beans. Ideally the trees should have between 40-80 inches of rainfall per year.
When all of the weather factors work out a surplus of cocoa beans can be exported and the price of chocolate is kept low.
If just one of the weather factors is not normal the chocolate industry suffers and prices increase.

and seen in several areas through the Northwest was caused byâ mountain pine beetles. His program also detected a similar pattern of damage caused by the western spruce budworm.
Outbreaks of pine beetles have occurred in several areas according to the release including near Mount Hood in the 1980s an outbreak that peaked in 1992
Another outbreak near Mount Rainier lasted 10 years from its onset in 1994 until the insects killed all the trees
 Pine beetles still pose a huge threatâ to forests throughout the West. Kennedy's program also recognized a subtler decline of forests near these two mountains.
These insects eat the needles off of spruce trees This won't kill trees immediately but will if the insects return in following years NASA reported.
Make sure to collect some dirt from around the base of a tree. You might also include some potting soil from the garden store. 2. Place each sample of dirt in a separate plastic bag.
oehow is the dirt from under the tree the same as the potting soil? oehow is the garden dirt different from the sand?

In the new study the FDA analyzed dietary supplements that were labeled as containing Acacia rigidula a shrub native to Texas. Products
whose labels claim to contain Acacia rigidula are marketed commonly for weight loss supposedly by suppressing appetite and burning fat.
Illegal ingredient It's not clear how long manufacturers have been using Acacia rigidula in supplements (or labeling their supplements as containing the ingredient) Cohen said.
At least six products sold at the nutrition retailer GNC contain Acacia rigidula according to a search of the company's online store.
Cohen said that it's important to note that Acacia rigidula has never been used in herbal medicine or herbal remedies.
In addition the FDA analysis found many supplements labeled as containing Acacia rigidula didn't actually include this plant as an ingredient.
The researchers compared the composition of dietary supplements labeled as containing Acacia rigidula with that of the plant itself.
None of the dietary supplements resembled Acacia rigidula in terms of their chemical composition. For example nearly all of the supplements had high levels of a compound called phenethylamine
Basically the label'Acacia rigidula'is being used as a cover for introducing a brand new synthetic drug similar to amphetamine Cohen said.
In light of the new findings people should avoid supplements with Acacia rigidula and if they experience side effects from supplements with this ingredient they should notify their doctor as well as the FDA Cohen said.
Even trees and plants fizz with the sound of tiny air bubbles bursting in their plumbing.
And bark beetles may pick up the air bubble pops inside a plant a hint that trees are experiencing drought stress.
But researchers who eavesdrop on plant hydraulics are discovering that certain species like pine trees and Douglas firs can repair the damage on a daily
or even an hourly basis. These cycles of embolism formation and refilling are just something that happens every single day.

and an expert on how trees respond to wind. How many times have sat you next to someone who has their car stereo at full blast?
Trees perceive and respond to touch like wind or an animal passing on a trail.
In fact a tree needs wind to grow Telewski said. If you stake down a seedling you do it a little bit of disservice
because a tree needs to perceive motion. It's like physical therapy for the tree. If you stake it too tight it does not allow the plant to produce stronger tissues.
But Telewski is open to the idea of plant communication by sound. He said in the last few years researchers in China have shown they can increase plant yields by broadcasting sound waves of certain frequencies.

Property owners in Maine have reported a startling increase in the theft of maple sap the sweet liquid that's used to make maple syrup the Montreal Gazette reports.
I don't think it makes a lot of sense you need a certain amount of trees to make this worth it
Not only are thieves skulking around private property to steal the sap they're also destroying old sugar maple trees by boring three
or four holes into them as large as 7/8-inch wide leaving the tree susceptible to disease.
Most tree tappers use just one or two 5/16-inch bores to tap a tree.
Drilling into the first board the lower part of the tree damages potential lumber and diminishes the value of that tree.
Costly though it may be the tapping of maple trees on private property pales in comparison to last year's heist of $18 million worth of refined maple syrup from a Quebec warehouse according to the New york times. The theft dealt a crushing
blow to Canada's strategic maple syrup reserve. Yes Canada has a strategic reserve of maple syrup
