Angel Falls drop nearly a kilometer (about 979 m) from a table-top mountain. The water seems to be dropping straight out of the clouds.

They have to make sure they do not fall down any of the big holes in the ice. They have to make sure they do not get lost. The winter months are very cold and dangerous. It is dark all the time. The winds blow strongly. Snow is picked up and blown around. The scientists often cannot see where they are going. They have to work inside the research stations too. The scientists study nature to understand more about our world. They learn more about the gases in the air. They find out how the weather changes over the years. They look at the ice and how it moves. The scientists also study the stars and space. All this helps us prepare for the future. No planes can reach them to bring food and medicines.
