A tidal bore is a rare natural phenomenon in which an incoming tide creates a wave of water that travels up along a river or a narrow bay causing water to flow against the river’s current.

Tidal bores occur in relatively few locations worldwide. In fact, for bores to occur, there are a few conditions that has to be met: the river must be shallow, must have a narrow outlet to the sea and a broad funnel-shaped bay. The bay must also have large tidal range - typically more than 6 meters between high and low water. The funnel-like shape not only increases the tidal range, but it can also decrease the duration of the flood tide, down to a point where the flood appears as a sudden increase in the water level.

A pingo, also called a hydrolaccolith, is a mound of earth with a core of ice found in the Arctic and subarctic regions, that can reach up to 70 meters in height and up to 600 meters in diameter. Pingos are formed as a result of what is called a “closed” system of unfrozen soil developing within an area of permanently frozen ground. Pingos usually grow a few centimeters per year, and the largest take decades or even centuries to form. Pingos eventually break down and collapse. Evidence of collapsed pingos in an area suggests that there was once permafrost.

Tuktoyaktuk in the Mackenzie Delta of the Northwest Territories in Canada has one of the highest concentrations of pingos, with some 1,350 examples. Pingo National Landmark protects eight of these features. Two of the most famous pingos are Ibyuk and Split. Ibyuk is about 50 meters high and is the tallest pingo in Canada and the second tallest in the world. It is the world’s largest growing pingo, and continues to grow at a rate of about 2 centimeters per year. Ibyuk is estimated to be more than 1,000 years old. Other pingos in the landmark range in height from 5 to 36 meters and represent various stages of pingo development.

A rare weather phenomenon that affects the area only about once a decade, filled the Grand Canyon in the U.S. with a dense, white fog at the end of November. The phenomenon, known as "temperature inversion," happens when the temperature profile of the atmosphere is inverted from its usual state, and cooler air is trapped at the earth's surface by warmer air above.

Typically, the temperature of air in the atmosphere falls the higher up in altitude you go. This is because most of the suns energy is converted into heat at the ground, which in turn warms the air at the surface. The warm air rises in the atmosphere, where it expands and cools. When temperature inversion occurs, the temperature of air actually increases with height. The warm air above cooler air acts like a lid, trapping the cooler air and fog at the surface and preventing it from rising.

California poppies bloom all over the state, but the western side of Antelope Valley in northern Los Angeles County is the most consistent poppy-bearing land, protected from grazing and other human interference. Each spring, this desert like area comes alive with millions of bright orange poppy flowers. The wildflower season generally lasts from as early as mid-February through late May, and depends on the amount of rainfall during the winter to early spring seasons. This area is now protected and called the Antelope Valley California Poppy Reserve.

OMG--that has to be one of the sweetest kisses ever! LOOK at that baby's face! Tears are running down my cheeks from laughing and going, "ahhhhhhhhhhhhhh!!!!!!"
