Moon

When the moon is out I’m usually sleeping or without my camera on a morning walk, but I got these shots late in October.  The moon is just as fascinating as the sun.  More so in many ways.

We always see the same side when we see the moon in the sky.  The moon’s shine comes from the sun reflecting its light off it.  

The phases we see the moon go through occur when the moon is orbiting around the earth.  The earth is what blocks the sun’s light from reflecting off the moon.  So as the earth and moon rotate around the sun and each other we see different phases of the moon. 

From a photographers point of view the full moon is the best and maybe the easiest to photograph but every different phase has its own beauty.  The brightness of a full moon to the darkness of a new moon.  Each makes the nighttime sky different every night.  I would not have thought of that.

Pack out what you pack in.

Rangers

I always stop at the ranger station when I hike in a state park.  Sadly, budget cuts don’t allow for enough rangers to man all stations all the time.  There are four reasons why it’s important for me to talk to a ranger before I go for a hike.

Reason number four – I need to buy a parking pass.  I don’t visit the state parks enough to make an annual pass pay for itself and I never have the correct change to purchase a parking pass at the self-pay station.

Reason number three – The rangers know the trail conditions on that day.  I do a lot of hiking in the winter.  Trail conditions change daily sometimes hourly.

One sunny, warm February day I drove up to the Kettle Moraine State Park – Northern Unit.  I wanted to hike the Parnell trail.  The ranger told me that trail was icy.  I didn’t bring my cleats so the ranger recommended the Butler Lake trail.  It was a wonderful hike.  I made a point to thank her for that suggestion.

Reason number two – It’s good to let somebody know where you’re hiking.  I often make last minute decisions to go hiking and my cell stays in the car.  The point of the hike is to get away.  Luckily, I’ve never had anything bad happen on a hike but it’s good to know that somebody knows where I am in case anything does.

Reason number one for stopping in at a ranger’s station when I visit a state park -  Heated Bathrooms.

Pack out what you pack in.

To Meadows


To Meadows
Robert Herrick
1591-1674


Ye have been fresh and green,
            Ye have been filled with flowers;
And ye the walks have been
            Where maids have spent their hours.

 You have beheld how they
With wicker arks did come,
To kiss and bear away
The richer cowslips home.

 Ye’ve heard them sweetly sing,
And seen them in a round;
Each virgin, like a spring,
With honeysuckles crowned.

But now, we see none here
Whose silvery feet did tread,
And with disheveled hair
Adorned this smoother mead.

Like unthrifts, having spent
Your stock, and needy grown,
Ye’re left here to lament
Your poor estates, alone.

Wind Creation

Wind is a constant.  Wind moves all the time.  Sometimes it moves fast and sometimes slow.  It depends on the atmosphere and the sun above.

The sun warms the air.  That warm air rises, the cold air sinks – creating wind.  The weather guys call this feud between warm and cold air fronts.  High pressure comes in on a warm front that moves about 15 miles per hour.   Low pressure follows a cold front.  They move at 30 miles an hour or so.  Wind always moves from high pressure to low.
 
The earth’s surface creates friction with wind and the friction slows the wind down.  Prairies, deserts, and parking lots don’t create as much friction as forests, mountains, and buildings.  Mountains and high rise buildings cause wind to move up but otherwise wind moves horizontally across the earth.

Cities do funny things to wind.  The buildings and asphalt collects heat from the sun during the day.  The city releases that heat slowly at night or on a cloudy day, creating thermals or updrafts of wind.  Birds love soaring on thermals.  Watch them.

Wind can also carry things.  Dust from Africa can be the basis for a snowflake in Wisconsin.  Wind can be damaging, too.  Straight line or tornado or hurricane-force all wreaking havoc on the things humans build.  It’s important to know what’s coming so you can get out of its way.

Pack out what you pack in.
