A crisp sunrise at Moraine Lake and the Valley of the Ten Peaks. Moraine Lake sits at an elevation of 1,885 m (6,183 ft) in Banff National Park. The iconic colour of the lake is due to light scattering from fine particles of glacial rock flour.
Mt St. Helens and Mt Adams seen from the air while flying over the Cascade Ranges in the US Pacific Northwest. Mt St. Helens (also known as Lawetlat'la to Cowlitz people, and Loowit to the Klickitat people) is a stratovolcano that erupted spectacularly in 1980 after a century of dormancy. The collapse of its northern flank after an earthquake measuring 5.1 on the Richter scale sent the explosion out from the north rather than the typical eruption from the top and created the 1.6km (1 mile) wide horseshoe-shaped crater that you see in this photo. The eruption killed fifty-seven people, destroyed 250 homes, 47 bridges, 24km (15 miles) of railways, and 298km (185 miles) of highway, and reduced the elevation of the mountain's summit from 2,950m (9,677 ft) to 2,549m (8,363 ft). Mt Adams 3,743 m (12,281 ft), seen in the background, has not erupted in more than 1,000 years however is not considered extinct. Cascade Volcanic Arc, Washington State, USA.
A full Easter moon rises at sunset over a lonely tree perched atop one of the salty hills the make up the Lake Mungo Lunette. Known as the Walls of China, the lunette is formed by wind blowing over the dry lakebed for thousands of years. It is found on the eastern edge of Lake Mungo which dried up some 14,000 years ago.
