Pluto and its satellite

With the help of modern systems of observation and astrological investigation astronomers managed to notice the possible active geysers similar to geysers of Saturn satellite.
Nowadays there are no photos of geysers. But the way glaciers are situated on the surface of the space object proves the existence of these geysers. In opinion of scientists the explanation of this fact is connected with discharge of the water mixed with ammonia that gets to the cold surface of the space satellite.
The period of geyser's activity may last from several hours to several days. And the substance released by the geyser may cover all the surface of the satellite with ice with the thickness 1 millimetre during 100 thousand years.
But in such case the question appears: "Where did this water come from if the temperature of the satellite is very law?" According to scientist the answer to this question is very simple, as ammonia plays the role of antifreeze.
