The Grand Canyon, Mount Everest and Loch Ness will vie with over 200 other spectacular places in the next phase of the global competition for the New 7 Wonders of Nature, organizers said.

The 261 nominees from 222 countries include some of the most famous mountain peaks, lakes, and other attractions, such as the Great Barrier Reef and Niagara Falls.

Over a billion voters are expected to join in online voting that will nominate 77 semifinalists for the top natural wonders, which will share in the glory already enjoyed by the seven man-made wonders chosen 18 months ago.

“We are calling on people all over the world to actively show their appreciation for our … natural world by joining together to celebrate the most extraordinary sites on our planet,” said Tia Viering, spokeswoman of the New 7 Wonders campaign.

The Swiss-based nonprofit foundation collected 441 nominations over the Internet since it opened the selection process in 2007.

The foundation then chose the top vote-getter from each country, making a list of 222 sites. The overall list rose to 261 with the inclusion of sites shared by two or more countries - such as Niagara Falls and Lake Superior between Canada and the United States and the Matterhorn, between Switzerland and Italy.

Voting for the 77 semifinalists will run through July 7. Registration on the website aims to prevent people from voting twice.
