兴趣爱好The Greenland Iceberg is an iceberg that stands at a record height of almost 47 miles. It is also the highest freestanding structure on Earth. It is a fascinating place to visit and a challenge for explorers. The challenge, it seems, starts when you try to get into the ice. This can be problematic because if you try to get in, you will first have to scale a part of the ice that is underwater. This means that you will have to travel hundreds of miles through the ice to reach land you otherwise wouldn't be able.
