Shining like Klondike gold

On August 16, 1896, two prospectors had their hopes literally pan out when they found a large deposit of gold along the banks of what would soon be known as the Bonanza River in the Klondike. And with that, Skookum Jim Mason (aka Keish) and his American brother-in-law George Carmack set in motion the Klondike Gold Rush—the richest gold strike in North American history. Because of the remoteness of the find, it would be over 11 months before the world found out. And it did so in the most dramatic fashion, when the steamers Portland and Excelsior pulled into Seattle’s harbor carrying over one ton of gold (worth over $1 billion in today's dollars).

The news reached the rest of the United States and Canada during a prolonged economic depression, which may help to explain why over 100,000 people quit their jobs (including the mayor of Seattle) and set out for the Yukon with dreams of striking pay dirt. But the trip was harrowing and arduous, and less than half of those who set out for the Klondike in Canada’s Yukon Territory wound up making it there. But the sudden influx of those who did complete the journey briefly turned Dawson City into the second largest city in Canada...and certainly the most expensive. Eggs cost $3 apiece (the equivalent of $81 today) and salt was literally worth its weight in gold. In the saloons of the boom town, a profit could be made by simply sweeping the floor and collecting spilled gold dust. Most who came lost everything. Today, Dawson City has a population of just under 1,400, making it the second largest city in the Yukon.

It's surströmming time

The historic wooden pier of Smögen, Sweden will be busy—and pungent—today. The third Thursday in August means one thing: surströmming season has arrived and all over Sweden, brave residents stand at the ready with can-openers in hand. If you've never taken part in a surströmmingsskiva, the Swedish word for this particular event, you're going to need a bucket of water, some side dishes, and a strong constitution.

In April and May, freshly caught herring from the Baltic Sea is quickly brined in just enough salt to keep the fish from rotting. In July, the rapidly fermenting fish is canned and then, come this day every summer, the cans are opened—outdoors and often submerged in a bucket of water to reduce the smell—and eaten with flat bread, potatoes, and usually a chaser of strong alcohol or beer. Some say sour herring, aka surströmming, is one of the most putrid smelling foods on Earth. Others say it's delicious.

An ice cap-puccino

No, that's not a new frozen coffee drink from Starbucks; it's the southern polar ice cap on Mars. Mars is the only other planet in the Solar System with a visible ice cap, though it differs from Earth’s because it is comprised of both water ice and frozen carbon dioxide. The ice cap looks smooth here, but its surface is pockmarked with swiss cheese-like depressions caused by the seasonal freezing and melting of the Martian winters and summers. While Mars has been observed by humanity for thousands of years, it was only on August 13, 1642, that Dutch astronomer Christiaan Huygens observed the ice cap using the most powerful telescope of the day. The giant of science designed the 50x magnification telescope himself, and with his brother, produced the lenses as well.

Storm rolls over the Badlands

Today's image of a thunderstorm moving over grasslands in the Theodore Roosevelt National Park shows the power of nature and the power of conservation. In 1883, Teddy Roosevelt, then a New York State Assemblyman, traveled to the North Dakota Badlands to hunt bison. During this trip, Roosevelt fell in love with the cowboy lifestyle and the freedom he experienced. Before heading back east, he became part owner of the Maltese Cross Ranch. A year later he was back in North Dakota and had built Elkhorn Ranch. Life in the west inspired Roosevelt, who began writing books and articles about it. He would go on to establish six national parks and 18 national monuments, greatly increasing the size of the National Park System.

At the Theodore Roosevelt National Park, the only US national park named after a person, you can see some of the places that helped inspire Roosevelt's conservation efforts. In the park's Elkhorn Ranch Unit, the location of his 'home ranch,' you can experience the same remoteness that he craved. At the South Unit Visitor Center you can see the cabin he used as his home during his first trips to the Badlands, now restored to its original state. And if that's not enough, hours of scenic drives, hiking trails with dramatic views, and wildlife watching are sure to make a visit to the area memorable for any visitor.

In the Supertree Grove

Every August 9, the streets of Singapore fill with revelers celebrating the anniversary of the city-state's independence from Malaysia. Like patriotic events in other nations, there are parades, speeches from political leaders, and fireworks. This year also marks the 200th anniversary of the first British colonial outpost in what would become modern-day Singapore.

We're joining in the fun by sharing this photo of the Supertree Grove—part of the Gardens by the Bay, one of Singapore's most ambitious and interesting public attractions. The entire park is designed to bring more nature into Singapore's dense, urban environment, and to show off some of the ecologically friendly construction ideas that concentrate on conservation and preservation. The 'supertree' structures in this grove collect rainwater, harness solar power, and even vent air into and out of nearby greenhouses.

Seville celebrates first world tour

Today in 1519, Ferdinand Magellan departed from Seville on his quest for a western passage to the Spice Islands. He sailed five ships and a crew of more than 230 men down the Guadalquivir, the river in today's image. The Triana Bridge, the oldest in Seville, was built 330 years after the expedition's return to the city in 1522. While successful in finding a western route to the Pacific Ocean and returning with valuable spices, it came at great cost. Only one ship, under the command of Juan Sebastián Elcano, and 17 other crew members completed the global circumnavigation. Magellan didn't. He was killed on April 27, 1521, at the Battle of Mactan in the Philippines.

Seville and other Andalusian cities will celebrate these milestone anniversaries as part of the 'V Centenario.' For the next three years—the same amount of time it took Magellan's fleet to sail around the world—there will be a slate of activities, including academic conferences, museum exhibits, nautical tours, educational events, and much more, to recognize, detail, and celebrate various aspects of this historic voyage.

Nubble Island's only industry

Cape Neddick Light sits on a tiny island called Nubble Island, or 'the Nub'—just 100 yards from the mainland of the cape. It's on Maine's southern shore and is one of just eight lighthouses in Maine that still use a Fresnel lens to amplify the light. The island isn't accessible to the public, but because it's so close, many visitors come to Sohier Park on the cape for the view of the lighthouse. Why August 7 for Lighthouse Day? Because it was this day in 1789 the US government placed all lighthouses under federal control to make sure these important safety signals were all built, supported, and maintained equally.

Storks ready for take-off

It's migration season for white storks, shown here tending to a nest at Los Barruecos Natural Monument in Central Spain. This destination is known for large, granite boulders intermixed with sculptures created by local artists—and it's a favorite stork nesting spot. In August and September, white storks depart their nests for a 25-day trip south to their African wintering grounds, where they gather in large flocks. The species returns to Europe again nine months later—hence its unique role in folklore, giving parents a low-stress way to answer the question ‘where do babies come from?'

A ‘Superior' paddle

The Apostle Islands National Lakeshore off the northern tip of Wisconsin is a paradise for kayakers and campers, and those who like to combine the two. The park includes 21 islands which, if you're willing to transport your own gear, offer uncrowded camp sites because, well, they're islands. Once you're in a kayak, you can explore some of the red sandstone sea caves, which are best appreciated from the water.

And yet, like many wild and rugged places that offer superlative views, be warned before venturing out. This is Lake Superior, the largest, deepest, roughest, and coldest of the five Great Lakes. Even on warm summer days, the water barely rises above 50 degrees, and the winds can be as fierce as any sea. So if you plan to kayak the Apostles, take care. Enjoy the adventure but make sure you check the weather report and prepare before paddling away.
