Some of the photos -
Summer wildflowers radiate colour in the sunset shadow of Mount Rainier, set in its own national park 54 miles from Seattle, Washington state. The 4,392-metre monster is an active volcano considered to be one of the most dangerous in the western hemisphere. It is a sister volcano to Mount St Helens (which famously erupted in 1980) in the Cascade range.

A bristlecone pine tree in Great Basin national park, close to the 4,000-metre Wheeler Peak in eastern Nevada. The trees grow on rocky glacial moraines and can live for 5,000 years. The area boasts some of the darkest night skies in the US, so is ideal for stargazing.

Monument Canyon, in the Colorado national monument, near Grand Junction city. The park, high on the Colorado plateau, preserves some of the classic landscapes associated with the American West. It contains a number of paths, such as the Serpent Trail and the shorter Devil’s Kitchen.

A moose grazes while keeping an eye open for danger in Denali national park, Alaska. Usually the animals stay hidden in the park’s forests, which offer some protection to them from predators such as wolves. Alaskan moose form a subspecies, often referred to as giant moose, which ranges between the US state and western Yukon.

Bison in Yellowstone national park, one of the last nearly intact ecosystems in the world’s temperate zones. The park’s bison herd is descended from a remnant population of 23 individual bison that survived the mass slaughter of the 19th century by hiding out in Yellowstone’s remote Pelican Valley.
