Crater Lake  
Look here for more info!

 

Crater Lake is a famous caldera national park in Oregon and it is definitely worth visiting it.
The lake lies in a caldera (produced when the center of the volcano caved in upon itself) 6600 years ago, with the destruction of formerly 3600 [m] high Mt Mazama.
A cinder cone, Wizard Island, raised in the lake at about 230 [m] over the surface of the lake.
Water is supplied only by snow and rain.
Little story: At the beginning of color pictures processing, Kodak was sending excuses to people who shot Crater Lake, saying that they were sorry about the color of the lake,
and that they probably should have goofed the products at process time: the lake is too blue.
But the lake is really that blue!
Sept. 1994

 

Mt.St.Helens

Mt St Helens global view. This volcano erupted for the last time on Aug. 18, 1980, and blew 1312 ft (400 m)
off the summit in a lateral blast, NE of the volcano, searing and flattening the forest.
The bulb you can see in the crater is the lava dome.
Also these pictures show how the trees were flattened by the lateral blast.
Of course, all the trees indicate the direction of the blast!

A trip along the ridge of the crater, and the top of crater.Juli 96


More pictures of what happened to the forests around the volcano.


The first two pictures show that Spirit Lake has been submerged by the huge deposits of the pyroclastic
flow in 1980 and is now higher in elevation than it used to be.
The white parts on the top of the lakes are destroyed floating logs.

 
A lot of lakes have appeared in the region. All the life you can find in them was brought by birds.

 

Devil's Tower, Wyoming




Devil's Tower is a wonderful example of basaltic columns. The place has been used as the meeting point in the Close Encounters movie. September 1999

 

Geyser Basin, Wyoming



Biscuit Basin, WY with sulfuric water. (First picture at 1659x445) - September 1999


Water dripping at the top of Canary Spring.
The white and yellow colors of the deposited travertine (which is a white mineral) indicates this section is near
a hot runoff channel. A little below this section the water cools a bit, allowing bacteria and algae to grow
in the pools of water. Those pools will then appear as orange, green, brown, etc.
September 1999


Geyser Basin hosts a lot of natural steamed volcanic phonomenons.
You'll find a lot of crystal clear basins, geysers, sulfic areas.
The first 2 pictures are Old Faithful Geyser. September 1999

 

Devil's Postpile, California



Devil's Postpile formation is similar to the Devil's Tower, Wyoming one shown above.
When you reach the summit, you'll have an opportunity to see the hexagonal columns in cross section.
The cutest husky in the world, Ninotchka, gives the scale. September 1999

 

Ubehebe, California


Ubehebe crater northwest of Death Valley in eastern California.
This is one of the biggest explosion craters on the Earth. Overheated ground water and magmatic gasses create
such craters in a single enormous explosion. This one at Ubehebe took place about 7000 years ago.
Prehistoric native Americans may witnessed it.

Black Point, California

 
This is a 13,000 years old underwater volcano, which erupted near the end of the last ice age. Cool waters of, at that time huge, Mono Lake cooled it rapidly
and during this process the top of the volcano broke and formed several hundred meters long cracks. March 1996 Pictures by Dr Amadej Trnkoczy

 

Sierra Nevada, California
