St. Patrick's Day
Get ready for shamrocks, parades, and all things green, because today is St. Patrick's Day. Many countries around the world recognize the holiday, but the first celebration was in Ireland more than 1,000 years ago. St. Patrick's Day, also known as the Feast of Saint Patrick, is both a cultural and religious celebration recognizing Saint Patrick himself, an Irish, 5th century Christian missionary and bishop.
This view is of Copper Coast Geopark, a UNESCO Global Geopark on the southeast coast of Ireland. The area also boasts a rich cultural heritage, and is dotted with numerous historical sites, including Iron Age forts, inscribed stones, and ruins of medieval churches. This magnificent stretch of undulating cliffs and sandy coves is named after the 19th century copper mines that once operated there.

Waimea Canyon and Waipo'o Falls, Kauai, Hawaii
Waimea Canyon, sometimes referred to as the Grand Canyon of the Pacific, is home to the picturesque Waipo'o Falls. The water that flows through the falls and canyon descends from Mount Wai'ale'ale, one of the rainiest places on Earth. Around 4 million years ago, a portion of the volcanic Kaua'i collapsed, creating a depression that the Waimea River has further eroded into today's canyon. If you want to see the true variety of Kauai, leave the beach behind and take winding State Route 550 into the mountains. Along the way you will see stunning views of the shore and the canyon before arriving at the lookout for Waipo'o Falls.
The rainbow connection
April showers bring rainbows, and on April 3, the celebration of Find a Rainbow Day. The rainbow shown here is at Victoria Falls in southern Africa on the Zambezi River, on the border between Zambia and Zimbabwe. Scottish explorer David Livingstone named the falls in honor of Britain's Queen Victoria, though it's also still called by its indigenous Lozi language name, Mosi-oa-Tunya, which means 'the smoke that thunders.' According to some historical records, local villagers described the falls to Livingstone as 'Seongo' or 'Chongwe,' which means 'The Place of the Rainbow,' since rainbows usually appear in the fall's constant spray. Under a bright moon, the falls will produce a 'moonbow.'
French philosopher and scientist René Descartes did some of the first studies of optics and rainbows around 1637--but no one at the time understood where the colors came from. In 1666, Isaac Newton explained that sunlight is really a mixture of the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet.
