Fascinating winter phenomenon – Snow rollers

A snow roller is a rare meteorological phenomenon in which large snowballs are formed naturally as chunks of snow are blown along the ground by wind, picking up material along the way, in much the same way that the large snowballs used in snowmen are made. Unlike snowballs made by people, snow rollers are typically cylindrical in shape, and are often hollow since the inner layers, which are the first layers to form, are weak and thin compared to the outer layers and can easily be blown away, leaving what looks like a doughnut or Swiss roll.

Oregon’s ‘Lost Lake’ disappearing through lava tubes

Image source

Oregon is home to the towering Cascades, a range of mountains and active volcanoes. The Lost Lake likely formed about 3,000 years ago, when lava flowing from a volcanic vent blocked a river channel and created the lake. The lake bed begins to fill in the late fall, when the amount of rain coming in starts exceeding the ability of the lava tubes to drain off the water. But during the dry months, the lake vanishes and turns into meadow. The reason? Two hollow lava tubes at the bottom of the lake are constantly draining the lake dry, much like a bathtub left unplugged. It’s not entirely clear where the water goes, but it possibly seeps into the porous subsurface underground. There have been numerous attempts to plug the leak, those endeavors, however, would only result in the lake flooding. Continue reading Oregon’s ‘Lost Lake’ disappearing through lava tubes

Morning Glory Cloud over Lake Michigan

The Morning Glory cloud is a rare meteorological phenomenon consisting of a low-level atmospheric solitary wave and associated cloud, occasionally observed in different locations around the world. The wave often occurs as an amplitude-ordered series of waves forming bands of roll clouds. The cloud often travels at the rate of 10 to 20 meters per second, sometimes as a single cloud, and sometimes in sets of up to eight clouds.

Dr. Zander’s Victorian-Era Exercise Machines

Swedish physician Dr. Gustav Zander  helped pioneer mechanotherapy, or the promotion of health and healing through exercise apparatus. Incorporating machinery allowed for less exertion, opening up therapeutic movement to those with injuries, deformities, and those just not in good enough shape. Zander constructed several devices which enabled constant and regular movement of individual parts of the human body, as well as certain devices that replaced the manual massage. He started his first institute in Stockholm in 1865 and gained international fame by exhibiting his devices at the International Exhibitions in Brussels and Philadelphia in 1876. By the time he released his book, Dr. G. Zander’s medico-mechanische Gymnastik in 1892, the Zander Institutes had gone worldwide and his machines were available in health spas across the globe.

Crown Shyness – A Phenomenon Where Trees Avoid Touching

Crown shyness (also canopy disengagement) is a phenomenon observed in some tree species, in which the crowns of fully stocked trees do not touch each other, forming a canopy with channel-like gaps. The phenomenon is most prevalent among trees of the same species, but also occurs between trees of different species. There exist many hypotheses as to why crown shyness is an adaptive behavior, and the most prominent theory, is that the gaps prevent the proliferation of invasive insects.

A fascinating golden bait trap

Russian artist Roman Booteen has created this Hobo nickel, which he titled “THE TRAP with GOLDEN BAIT.” A carved Morgan dollar, featuring a 1945 gold 2-peso coin from Mexico serving as “bait” in the middle. The coin also features a mouth of teeth that act as a trap jaw. The trap jaws are triggered when the gold coin is pressed.
