The caves in the depths of the glacier
Ice caves are noteworthy for many reasons, but primarily because they have done in the snow and ice, and not in the mountain rocks. Rout water in the glacier, these caves are very unstable. When glacier moves, the same thing happens with the tunnels and caverns inside it. Researcher Brendt McGregor and forester Eddie Cartaya 3 documented caves Rout in Sandy Glacier, Oregon that is located on the mountain.
Take a look at some of the proposed McGregor photos taken to preserve the beauty of these amazing caves. Because soon they will disappear from the face of the Earth.
The first expedition
This photo was taken in January 2012, when MacGregor Cartaya and conducted the first large-scale study of the cave Snow Dragon. Entrance about 600 meters wide at that time sealed the winter snow, creating a wall height of 9 meters. If the researchers even came a week later, it is quite possible that the entrance was blocked completely. The dark bands in the ice a bit like the annual rings on trees, but in fact it freezes for centuries in the ice rocks.
The expedition members Cascadia - Brett Gallagher and Tyler Debudt - photographed at the entrance to the Snow Dragon a few minutes before sunset in July 2013. According to McGregor, he would not be surprised if the cave in 2016 will be completely destroyed: the holes, so-called "roof windows" in the walls of the cave create a draft, gnawing away at the underground passage.
The light show
In this photo Amelia Templeton of Oregon Public Television stands in the fiery rays of the July sunset. Exposure to sunlight makes the dripping water from the ceiling like a laser show. On the ceiling of the cave can be seen what is called firnizirovanny snow.
The cave is pure fiction
In this photo captures the cave pure fiction, one of the three caves that found McGregor in 2011, the expedition. Thinning ice has facilitated access to the caves, but researchers always have to be on guard, because Sandy is constantly moving.
The upper cave entrance
The upper entrance to Fudge is a vertical hole, and the title McGregor Cartaya "Cerberus". This passage does not look big enough to photograph, taken in November 2013, but in fact has a diameter of about 24 meters. Everything looks pretty serene at first glance, if you do not know what's inside is very noisy, due to the current through the water cave.
Panorama from inside the
The photo was taken about an hour the night in November 2013. Prominent on the horizon Portland illuminated electric glow. The cone at the left edge of the entrance to the cave was created by the snow falling through the upper hole in the cave. In the center of the exhibition - snowshoes McGregor.
The lower passage
The lower entrance to the pure invention, taken outside the cave in November 2013. This photo shows where underground passage begins in the upper left corner you can see the edge of the glacier.
Glacier Changes are inevitable
There captured researcher John Waller, standing at the entrance to the cave Snow Dragon. In the creation of ice on the walls of the gear engaged flows of warm air, walking on the grotto. According to McGregor, 2014 was the year when the glacier just changed rapidly. Snow Dragon then completely gutted. This is one of the last photographs in which the cave is still in good condition.
Frozen waterfall about 30 meters high, was filmed in December 2013 within a pure fiction. It was formed from water, which seeped through cracks in the ice until the formed hole with a diameter of about 6 meters. According to McGregor, this hole will grow to 60 meters in the summer of 2015 and will lead to the collapse of the cave entrance.
The highest of these stalagmite reaches a height of 35 cm. The stones on the left in the background can be seen the orange labels used for the application ice maze at stake. McGregor and Kartayay who first mapped the cave system, which reached a length of two kilometers. Unfortunately, every year it is reduced to 30 meters due to the movement of the glacier and avalanches.
A farewell glance
made in January 2015, this photo is the last view of the entrance to the Pure fiction. And by the way, the entrance has expanded considerably over the years. "Whoever coined the phrase" moves with the speed of the glacier "just did not see the glacier Sandy" - jokes McGregor.
