How Trees Survive
As glaciers grow, they essentially crush everything that gets in their way. They do, however, gather up dirt and rocks as they go. This type of silt is referred to as a moraine by scientists. This moraine can provide as a cushion for some of the material that would otherwise be crushed by the glacier. This is also true for certain old forests. Rather than uprooting and damaging forest trees as the glacier moves, the moraine allows a layer of non-abrasive material to buffer the flow. When glaciers recede, you can find complete woods in some places, such as this one in Alaska.

Ice As A Preservative
The huge question on everyone’s mind is how ice can keep these things so well. The solution appears to be that the climatic conditions prevent bacteria and decomposers from functioning normally. In the Arctic, a lack of oxygen also causes bacterial decomposers to cease operating. They will operate at a much slower rate than usual, if at all. Because of this, scientists may analyze well-preserved sacrifices, woolly creatures, and other fascinating things. Isn’t it spellbinding?
