More than half the world's geysers are in Yellowstone National Park. VOA

January 2, 2018: When you think about America’s national parks, what probably comes to mind first is America’s first national park – Yellowstone. It’s also the first national park in the world, established by Congress in 1872, even before the National Park Service was set up.

Yellowstone sits on an active volcano, the source of the more than 10,000 geothermal features in the park, including more than half the world’s geysers. National Parks traveler Mikah Meyer made sure he caught the eruption of the best-known of its 500 geysers – Old Faithful, which shoots a column of superheated water up to 42 meters into the air, every 60 to 110 minutes.

“They have geysers that range from Old Faithful to these geysers that are basically holes in the ground that give a glimpse into what the bubbling boiling earth underneath is like.”

And some of what bubbles up is mud. Mikah describes these ‘mudpots’ as a witch’s cauldron. “They look like some sort of witch’s concoction because you’re just walking along this boardwalk and suddenly to your left and your right you’ve got these giant mud pools that are bubbling up in random spots, and so it really is a place where you can see the earth’s underbelly.”

He noted a constant feature of the park — steam. “Anywhere you are in the park it always seems like somewhere in your 360° view you’ll see some steam rising out of the ground.” These fumaroles, or steam vents, are the hottest hydrothermal features in the park, with temperatures as high as 138°Celsius.

Yellowstone is also home to thermophile microbes, which thrive in the hot springs. Trillions of these microorganisms are grouped together, so they appear as masses of color. Since different types of thermophiles live at different temperatures within a hot spring, they produce what looks like a rainbow in the water.

And it’s not just hot water shooting up… Yellowstone also has 350 identified waterfalls that tumble down more than 4 1/2 meters. The Lower Falls of the Yellowstone River is the tallest cascade in the park. At 94 meters, it’s twice as high as Niagara Falls.

An abundance of wildlife

Many of the more than 4 million visitors to Yellowstone each year come to see one of the symbols of the American West. Yellowstone is the only place in the United States where bison have lived continuously since prehistoric times, and the park’s herd of 4,000 to 5,000 animals represents the last-known wild bison population in the world.

Mikah said they really catch visitors’ eyes. “I have this video of what I call a Yellowstone traffic jam which is basically anytime there’s any sort of animal on the side of the road, everyone seems to stop their car and take pictures or pull over and it’s an instant traffic jam!”

But bison aren’t the only iconic animals in the park. Yellowstone is home to the largest concentration of mammals in the lower 48 states, including predators like grey wolves and bears, and large herbivores, like big horn sheep, elk and moose.

Two decades ago, 41 wild gray wolves from Canada and northwest Montana were released in Yellowstone National Park to start a recovery effort. Today, the park is home to more than 100 animals in eleven packs. (NPS/Jim Peaco). VOA

There are nearly 300 species of birds, 16 species of fish, five species of amphibians, and six species of reptiles.

But the main draw remains the regular eruption of Old Faithful. “If you’re on the hunt for geysers,” Mikah concludes, “you really can’t do much better than Yellowstone National Park.” (VOA)

Pickles bottled in various combinations

India is known for its pickles, popularly called 'Achaar', even across the world. But who thought about the idea of pickles in the first place? Apparently, the idea of making pickles first came from the ancient civilisation of Mesopotamia, where archaeologists have found evidence of cucumbers being soaked in vinegar. This was done to preserve it, but the practice has spread all over the world today, that pickles mean so much more than just preserved vegetables.

In India, the idea of pickle has nothing to do with preservation, rather pickle is a side dish that adds flavour and taste to almost anything. In Punjab, parathas are served with pickle; in the south, pickle and curd rice is a household favourite, and in Andhra, it is a staple, eaten with everything. The flavour profile of pickles in each state is naturally different, suited to each cuisine's taste. Pickles are soaked in oil and salt for at least a month, mixed with spices and stored all year round. Mango season is often synonymous with pickle season as a majority of Indians love mango pickle. In the coastal cities, pickles are even made out of fish and prawns.

Spiral bound notebooks allow writers to easily access each part of the page

It is impossible to detail the history of bookbinding without understanding the need for it. A very useful, and yet simple invention, spiral coils that hold books together and allow mobile access to the user came about just before WWII, but much before that, paper underwent a massive change in production technique.

Beginning in China, paper was made of bamboo sticks slit open and flattened. In Egypt, papyrus was made from the reeds that grew in the Nile. In India, long, rectangular strips of palm leaves were stitched together to form legible documents. When monasteries were established, scrolls came into being. Parchment paper, or animal hide, also known as vellum, were used to copy out texts periodically to preserve them. Prior to all this, clay tablets were used to record important events, and in some cases, rock edicts were made.

To keep the value and quality of what you offer, whether it's a romantic breakfast in bed or a royal wedding gift that will be remembered for years. The concept of gift-giving has taken on a number of shapes in today's society. Devina Singhania, the Founder of 'LE JAHAAN', a local home and decor accessories company, explains how the gifting paradigm has shifted.

Q: What do consumers expect from the gifting business and packaging designers these days?

A: Today's consumers are expecting more minimal sustainable products, designs and mediums. They are now more conscious about how their purchase affects the environment. Considering this shift in consumer buying, it's extremely important for companies to increase their commitments to responsible business practices and design products that are meant to be reused or recycled.
