The recent cold temperatures have created some beautiful frost around the area. Photos from Lem Marsh in Grinnell, Kansas show two different types of frost.
They include hoar frost, or white frost, caused by a deposit of interlocking ice crystals formed by direct contact with objects, usually those of small diameter freely exposed to the air, such as tree branches.
Frost on windows, as pictured below, is caused when moist indoor air encounters glass exposed to freezing temperatures from the outside.
During cold winter days, it is wise to be aware of the temperature and the wind chill to avoid frostbite and hypothermia. While the best way to avoid hypothermia and frostbite is to stay warm and dry indoors, when you must go outside, dress appropriately. Wear several layers of loose-fitting, lightweight, warm clothing. Trapped air between the layers will insulate you. Remove layers to avoid sweating and subsequent chill.
Outer garments should be tightly woven, water repellent, and hooded. Wear a hat, because half of your body heat can be lost from your head. Cover your mouth to protect your lungs from extreme cold. Mittens, snug at the wrist, are better than gloves. Try to stay dry and out of the wind. For more information check out the following web pages:
