Two more photos from 3 years ago

Hoar Frost seen here among the trees of the Golf Course, Baker City, Oregon
What happened three years ago on this day here in Baker City was too beautiful and spectacular not to share with you at least two more photos of that amazing nature display that was as unique as it was rare. I've been here in Oregon for 9 years now and that was the only time I saw the hoar frost covering every square inch of the Baker Valley. So my conclusion is that it must be a rare event. Enjoy the photos, praise God and for those who are a little bit more scientifically and metereologically minded, here is some more information about why this phenomena happens.

According to nature encyclopedias, Frost is the solid deposition of water vapor from saturated air. It is formed when solid surfaces are cooled to below the dew point of the adjacent air as well as below the freezing point of water. Hoar frost (also called radiation frost or hoarfrost or pruina) refers to the white ice crystals, loosely deposited on the ground or exposed objects, that form on cold clear nights when heat losses into the open skies cause objects to become colder than the surrounding air. A related effect is flood frost which occurs when air cooled by ground-level radiation losses travels downhill to form pockets of very cold air in depressions, valleys, and hollows. Hoar frost can form in these areas even when the air temperature a few feet above ground is well above freezing. Nonetheless the frost itself will be at or below the freezing temperature of water.
