1 Earlier this week, I awoke to a dense fog covering the farm. Here I was at my boxwood allee looking across the south paddock - you can see my home in the distance.
2 Fog is made up of millions of tiny droplets of water floating in the air. It forms when the surface air is cooler than the air passing above. This happens often when the earth radiates heat at night or in the early morning. Since I live near the Cross River Reservoir, where there is additional moisture, when the air is cooled, and the vapor starts to condense, patches of fog emerge.
3 Fog reduces visibility to less than one-kilometer, or six-tenths of a mile. It can really impair driving or even walking.
4 Look at the thick fog across the paddock, shielding much of my house from view. The foggiest place in the world is the Grand Banks off the island of Newfoundland, Canada. It gets more than 200-days of fog per year.
5 The fog drifts over and between the horse paddocks and this of allee trees. The foggiest place in the United States is Point Reyes, California, which also sees about 200-days of fog annually.
6 Fog typically dissipates as the morning progresses. I captured the sun's rays beating down through the fog as I drove along the boxwood looking toward the American beech tree grove.
7 Here is another view of the fog from the boxwood allee.
8 The fog appeared to cover everything. The thicker the fog, the longer it takes to dissipate. The tall white pines can be seen above the fog on the right.
9 Don't confuse fog with mist - mist is actually easier to see through. Visibility is at least one-kilometer with mist. Visibility below this is fog.
10 As I turned toward my equipment shed, the fog could be seen in the southeast paddock on the right.
11 Here, the fog covered one of the lower fields - the majestic weeping willows were barely visible. Some areas, including parts of northern New England, the Appalachians, and the Pacific Northwest are more prone to fog. How much fog do you get where you live?
12 Another look across the lower field at the weeping willows. Some describe fog to be "as thick as pea soup". This was originally used to describe the dingy yellow smog from burning soft coal common in Europe. Such fogs occurred in London until the Clean Air Act of 1956.
13 Here is another view of the thick fog in the lower field.
14 Dense fog is when visibility is at least one-quarter mile or lower. And, when fog mixes with air pollution, it's called smog.
15 Here is the boxwood allee in the opposite direction - the fog is in front of the stable.
16 The fog looked to be dissipating just a little through the lawn towards my six weeping hornbeams.
17 This is my clematis pergola.
18 More fog in the distance as seen through the south paddock from my Gravenstein apple espalier.
19 Look at all the beautiful red apples in this Gravenstein apple espalier - they are ready for the picking.

22 The fog was also over the miniature donkey paddock.
23 Fog during the summer will only happen with clear skies and 100-percent humidity. We've had a lot of clear days - in fact, we really need some rain.
24 The fog looked very thick across the paddock as I neared the stable.

26 The boxwood allee as seen from my stable - the large rock on the left is one of three mounting blocks I use to get on and off my dear Friesians.
27 The entrance to the horse paddock - my home is hard to see through the thick fog, but it is there.
28 As I neared the end of my tour around the farm on this early morning, the fog lifted to clear, blue skies.
