Asphalt Lakes And The Secrets in Their Depths

Some of the world’s strangest lakes are filled not with water but with asphalt, also known bitumen, the same material that roads are paved with.

The great majority of asphalt that is used today is derived from petroleum, but asphalt is also found in concentrated form in nature. Sometimes they seep from the ground and create large puddles known as tar pits or asphalt lakes. At other times, they are found soaked in sands, as in Athabasca oil sands in northeastern Alberta, Canada, which is the world’s largest deposit of natural bitumen. Asphalt is also known to erupt in underwater volcanoes, but these are relatively rare and were discovered only in 2003.
There are only a few known large asphalt lakes around the world. The largest of these is located in the village of La Brea in southwest Trinidad, and is called the Pitch Lake. The lake covers about 40 hectares and is reported to be 75 meters deep. The liquid asphalt is so thick and viscous, that the surface can be walked upon. But if you stand on the surface for too long, you will slowly sink into it. Although the lake appears quiescent the asphalt is slowly moving and you can see flow lines on the surface. As the tar moves, sometimes prehistoric trees and other objects that had fallen into the lake appears, then disappears and then reappears again.

The lake was created thousands of years ago by the process of subduction when the Caribbean continental plate was forced under another plate. This opened fault lines that allowed crude oil from deep underground deposits to rise to the surface, where it collected in a volcanic crater. The air caused lighter elements of the oil to evaporate, leaving behind the heavy asphalt, a mix of oil, clay and water.

The lake was discovered in 1595, and has been commercially mined since 1867. An estimated 10 million tons of asphalt has been extracted from the Pitch Lake so far. About 6 million tons of asphalt is still left.

The La Brea Pitch Lake is also a tourist attraction and brings about 20,000 visitors annually. Sometimes people swim in the waters of the pitch lake because they believe it has therapeutic properties.









Soldiers’ Field Rations From Around The World (9 pics)

Italy
The Italian ration pack contains a breakfast shot of 40% alcohol cordiale, a powdered cappuccino, lots of biscotti, and a disposable camping stove for heating parts of the meal, including a pasta and bean soup, canned turkey and a rice salad. Dessert is a power sport bar, canned fruit salad or a muesli chocolate bar.

United Kingdom
The British pack is dotted with familiar brands from Kenco coffee and Typhoo tea to a mini bottle of Tabasco. The main courses include the British favourite, chicken tikka masala, and a vegetarian pasta. There’s also pork and beans for breakfast, and lots of sweets and snacks from trail mix to an apple “fruit pocket” that looks like it might not be out of place in a school lunchbox. Plus packets of Polos and, of course, plenty of teabags.

United States

Almond poppy seed pound cake, cranberries, spiced apple cider (the hot US non-alcoholic drink) and peanut butter and crackers make up this very American meal package. The main – pasta with vegetable “crumbles” in spicy tomato sauce – is less traditional, but the “flameless heater” shows off American tech skills – just add water to the powder in a plastic bag and it heats up enough to warm the plastic meal pouch.

 Australia
The Australian ration pack has more small treats than any of the others. Most of it is packaged by the military, from a serving of love-it-or-hate-it Vegemite to jam sandwich biscuits and a tube of sweetened condensed milk. The bag includes a can-opener-cum-spoon for getting at the Fonterra processed cheddar cheese, and main meals of meatballs and chilli tuna pasta. There are lots of sweets and soft drinks, and two unappetising-looking bars labelled “chocolate ration”.

Spain
The Spanish lunch pack has cans of green beans with ham, squid in vegetable oil, and pate. There is also a sachet of powdered vegetable soup, peach in syrup for dessert and crackers handed out to go with the meal in place of bread (not shown). There is a disposable heater with matches and fuel tabs, as well as lots of tablets: Vitamin C, glucose, water purification, and rehydration.

Canada
While there are Bear Paws snacks in the Canadian ration pack, there’s the shocking omission of maple syrup. You have the choice of salmon fillet with Tuscan sauce or vegetarian couscous for the main meal. There is also the makings of a peanut butter and jelly (raspberry jam) sandwich for breakfast.

Norway
The Norwegian pack has American technology (the flameless heater) but British tastes. There is Earl Grey tea, beans and bacon in tomato sauce, a golden oatie biscuit and Rowntree’s Tooty Frooties.

Germany
The German ration pack contains several sachets of grapefruit and exotic juice powder to add to water, and Italian biscotti, but also more familiar treats such as liver-sausage spread and rye bread, goulash with potatoes, and for breakfast sour cherry and apricot jams.

Estonia
Stuffed peppers, chicken-meat pâté, smoked sprats, and liver sausage with potatoes make an eclectic menu here. Plus, crispbreads on the side, and halva with vanilla for dessert. Breakfast is muesli, a fruit pocket and honey.

What 2,000 Calories Of Our Favorite Foods Look Like (8 pics)

2,000 calories is the average number that the average person should consume per day. But this number may seem a bit abstract. So, let’s take a look at how these 2,000 calories actually look like.

A Whopper — with lettuce, tomatoes, ketchup, mayonnaise, and pickles — from Burger King contains 630 calories, so it would take three of them to reach 2,000 calories.
A large fry from McDonald's has 510 calories, so it would take four of them.

A slice of a large Domino's pizza is 290 calories, so it would take 6.9 slices.

A can of Coca-Cola contains 140 calories, so it would take just over 14 of them.

An average apple has about 126 calories, so it would take roughly 16 of them.

Each Reese's Peanut Butter Cup has 110 calories, so it would take 18 of them.

A regular-size banana has 112 calories, so you'd have to eat 18 of them to reach 2,000.

A large carrot has only 30 calories, so it would take 67 of them.
