The narrow, 220 km wide Khatanga gulf is believed to hold 9.5 billion tons of geological reserves. Despite being one of the least accessible areas in the Russian Arctic, with the nearest 2.500 population Khatanga town 350 km away, oil industry development of the area is being considered.

Bear Glacier, the largest glacier in Kenai Fjords National Park, Alaska, is separated from the ocean by a large terminal moraine forming a proglacial lake which attracts numerous sea kayaking enthusiasts. The 20 km long glacier has two remarkable medial moraines, formed by joining ice streams. These moraines contrast with the brighter ice and appear clearly in Sentinel-2 images. However, the stunning features of the glacier may not be observable for long: a recent study has shown that Bear Glacier has been dramatically retreating (237 m per year) over the two last decades.
A stunning glacier Grey located in Chilean Torres Del Paine National Park is 6 km wide and over 30 meters high at the glacier's front. Its various shades of grey and blue, clearly visible even from space, attract many visitors each year. In 2017 a huge (380 m x 350 m) iceberg ruptured from the glacier with the cause unknown. Such events are very rare, with the last one occurring in the early 1990's. Due to its diverse plants and wildlife, glaciers, rivers, lakes and pampas, the park became protected as a UNESCO Biosphere reserve in 1978.
An ice tongue is a natural phenomenon, which occurs when a valley glacier moves very rapidly out into he sea or a lake. The Erebus ice tongue glacier in Antarctica comes down from Mt. Erebus and protrudes off the coast of Ross Island, forming an 11-12 km long ice tongue—a long and narrow sheet of ice projecting out from the coastline. When the sea ice in McMurdo Sound thaws in the summer, the ice tongue floats on the water without thawing. It also calves off in places forming icebergs. The Erebus Ice Tongue is only about 10 meters high, so its icebergs are small. When the ice around the tongue melts in the summer, waves of sea water constantly batter the edges of the tongue, carving very elaborate structures in the ice, sometimes producing deep caves at the margins. In the winter, the sea freezes once more around these new shapes.

Byrd Glacier is one of the largest fast-flowing glaciers in Antarctica. Ice flows from the East Antarctic plateau into the Ross ice shelf at a rate of ~800 m per year along the centre line of this ~20 km wide and ~100 km long glacier. Distinct longitudinal flow stripes are clearly visible from space where the ice is funnelled between the Transantarctic Mountains. Similarly to other Antarctic glaciers, Byrd Glacier is vulnerable to warming temperatures that lead to an acceleration of the ice flow, with disastrous effects on sea-level rise.

A winter landscape of the Christina Lake Oil Sands Factory. The factory uses specialized technology to drill and pump the oil from 375 meters deep underground. The project is expected to last for more than 30 years and produces 210.000 barrels of oil per day. In winter, the lakes are covered by snow, giving them a surreal white color.
