Hopewell Ceremonial Earthworks (Mound City) | USA

This property is a series of eight monumental earthen enclosure complexes built between 2,000 and 1,600 years ago along the central tributaries of the Ohio River. They are the most representative surviving expressions of the Indigenous tradition now referred to as the Hopewell culture. Their scale and complexity are evidenced in precise geometric figures as well as hilltops sculpted to enclose vast, level plazas. There are alignments with the cycles of the Sun and the far more complex cycles of the Moon. These earthworks served as ceremonial centres and the sites have yielded finely crafted ritual objects fashioned from exotic raw materials obtained from distant places.

Natural System of Wrangel Island Reserve | Russia

Located well above the Arctic Circle, the site includes the mountainous Wrangel Island (7,608 km2), Herald Island (11 km2) and surrounding waters. Wrangel was not glaciated during the Quaternary Ice Age, resulting in exceptionally high levels of biodiversity for this region. The island boasts the world’s largest population of Pacific walrus and the highest density of ancestral polar bear dens. It is a major feeding ground for the grey whale migrating from Mexico and the northernmost nesting ground for 100 migratory bird species, many endangered. Currently, 417 species and subspecies of vascular plants have been identified on the island, double that of any other Arctic tundra territory of comparable size and more than any other Arctic island. Some species are derivative of widespread continental forms, others are the result of recent hybridization, and 23 are endemic.
