Dad's Last Photos
May 4, 6:15 PMBroken Bow, Nebraska
Barb (Zierlein) and Dahl Jungren, and Rich, family of Everett Zierlein in Broken Bow Nebraska, along with the Webers from Arnold.
Barb, maybe you can describe who is who here.
Monday, May 5, 6:28 PMCody Wyoming: family of Leonard Zierlein.
Frank and Glenda (ZierLein) Willis, Uncle Leonard and Aunt Carol, Dad and Uncle Bob.
Monday, May 6, 12:56 AMCody Wyoming: more family of Leonard Zierlein.
Dad, Kim, baby Toby, Auggie, Louis, Aunt Carol, Uncle Bob, Uncle Leonard
Obviously, Dad's camera clock is about six hours off. The first two photos were taken near noon, judging by the angle of the Sun, so the third was probably taken sometime around 6:00 PM.
UPDATE: The third photo was taken at about 8:30 PM on May 5.

Beaver Relocated
For the past several years I have seen signs of beaver along the Cedar River. Last winter he started really attacking some gigantic Cottonwood trees, cutting one down altogether, and killing three or four more by girdling them (chewing off all the bark, all the way around. Today I walked over to see how he was doing and discovered that the Parks Department has cut down the dead trees and put wire mesh around the remaining trees to stop the chewing. I also heard a rumor that they had trapped 9 beavers, or trapped one beaver 9 times, and relocated him upstream. Maybe this is the last we'll see of the beaver for a while.
Here in this first photo you can see three stumps, all that remains of three awesome Cottonwood trees.
This second photo shows the freshly chewed wood over the top of the dark brown older chewing marks. The whole trunk is now surrounded by 1/4 inch wire mesh.
This third photo shows the tree the beaver successfully cut down and then stripped of all of its bark. Notice that the beaver only had to chew away the outer layer of wood since the Cottonwood's heartwood was already rotten and was unable to support the weight of the tree.
This last photo shows a close up of the teeth marks on the log that had been laying in the river. You may have to download the full size photo and zoom in to see the teeth marks.

Comet ISON Approach
Comet ISON has the potential to be one of the most amazing comets of a lifetime. It's orbital trajectory has it passing so close to the Sun that it may evaporate into a gigantic cloud of dust and debris that would be visible with a naked eye in daylight. Today the comet is 1/3 the distance from the Sun as the Earth and it is still descending toward perihelion.There are multiple images being posted on the Internet and they frequently generate the question, "which way is up?" This posting might help to show which way things are moving, and which way is "up" from the perspective of a person standing on the ground, on the planet Earth.
This first excellent photo was taken from the ground, likely with telephoto magnification. Except for the magnification this is the way the comet would have appeared if you were to see it with the naked eye or with binoculars. The Sun is below the horizon to the left, and the comet's tail is extended up and to the right, away from the Sun.
Here is an image from my SkyMap software, showing the positioning of these objects before dawn this morning, looking southeast from my house. The horizon is the border between the blue and grey backgrounds. The white line is the ecliptic, the apparent path of the Sun caused by the orbit of the planet Earth around the Sun. The Sun is shown as a hollow yellow circle on the ecliptic below the horizon. Notice the angle of the ecliptic, up and to the right, generally in the same direction as the photo above.There are two comets showing on the map, comet Encke and comet ISON. Planet Mercury (and Saturn very much farther away) is also lined up near the comets. Encke and Saturn are not very bright so I will not make much note of them.
Here is the really interesting photo, taken from a spacecraft designed to watch the Sun. The objects are labeled but their relative positions are confusing. Where is the spacecraft positioned so it could capture this image? How can the planet Earth be in the image along with the comets and Mercury all at the same time? Which way are things moving?Professional astronomers have looked at so many images where orientation is rearranged that they don't even notice when it looks odd like this. So they didn't bother to explain this one.
The answer is easily demonstrated by flipping the image horizontally. Extend a line from the Sun (on the left) through the planet Earth to represent the ecliptic. Note that Mercury is above the line and the two comets are below the line. This matches the SkyMap image very well. Rotate the photograph by 47 degrees and it will look even more like the SkyMap image.Now you can see that the north pole is up, Earth is in the foreground, moving toward Mercury and the comets, and rotating in that same direction. So when you are facing toward the comets, Mercury, and the rising Sun, the spacecraft that took this photo is behind you.

Comice Pear Harvest 2013
Today we decided it was time to take the Comice pears off the tree. They're not ripe but we've been losing so many of them to the raccoons and the birds that we decided it was time to cut our losses.
About half of the pears have either fallen off or been picked off by raccoons. They were all from the lower branches, leaving only the highest pears still on the tree where they were ravaged by birds.
This second photo shows what we managed to salvage from the upper branches. We've had so many fruit flies around here lately that the pears will not last sitting on the counter, so we'll have to eat them or make something with them while they're still not quite ripe.
As green as they are, they're still very sweet. They taste sort of like a Red Delicious apple.

New Bat Photo
Last week Bugsy the bat was hanging from the window screen rather than the bamboo shade. So this time he was facing the camera. It's still not a very good photo but you can see his ears, and it is definitely a bat in this photo.
Why doesn't he like the nice new bat house I built for him? It's much more private, and it's located right over the flower beds so his little bat droppings won't fall on our window sill. Best of all, the bat house doesn't roll up at night. When that happens, he still hangs out between the roll of bamboo and the outer flap covering the pulley and pull string locking hardware.
Sometimes he doesn't return in the morning. We suspect he may have a girlfriend.

STP 2013
Last Saturday, July 13, Lief rode his bike with his friend Tim from Seattle to Portland, participating in the annual "STP" bicycle ride.
They left the University of Washington campus in Seattle at 4:45 AM and I waved them by at 5:41 AM in Renton. Then I packed up my car and headed south on the freeway, to catch up with them in Centralia. They picked up three friends along the way, so there were five of them when I found them in Centralia. Notice Tim, in the blue and black kit on the left, still wearing his leg warmers in 75 degree weather.
The next photo shows them across the Columbia River from Longview. Tim is still wearing his leg warmers, but when they stopped here to take advantage of the spare water I was carrying, he finally took them off. The temperature was 85 degrees.
The bike in the foreground is not part of their group, but unfortunately by this time they had left two of their new friends behind. The one remaining new friend is Adam.
In this photo you can see Tim is still leading the group, with his leg warmers off. Another thing you can see here is Tim's strategy to keep the group going as fast as possible. He would push the pace a bit faster, then when they began falling behind, as in this photo, he would back off and let them catch up again. In this photo they were cruising at about 27 MPH with a tailwind.
Except for the shuffling of traffic lights, all three would have arrived at the finish line at the same time. Here is Lief just prior to entering the finish line gate. If I had a faster camera I could have also captured a photo of Tim and Adam.
Finally, after crossing the finish line the three intrepid cyclists posed for a photo together. Notice the lighting of a late afternoon (6:00 PM) rather than an evening twilight (8:00 PM) photo like it was when I rode that route. Their average speed, while moving, was more than 20 MPH.
Not included in this collection, are photos of salt encrusted shirts and wind blown hair both on heads and on legs.

The Bat is Back
After all my work building a nice house for bats, that crazy little creature decided to come back to the bamboo shade outside our living room window this summer. The bat house is empty.
Those bamboo slats measure about 3/8" and if you don't count the one leg stretched out that he's hanging from, he measures about four slats from the tip of his rear end to the tip of his ears. I measured four slats on another shade and found four of them measure 1-5/8" so he's just a tiny little guy.
Maybe as the days progress, and he moves from one place to another for maximum sleeping comfort, he may still find the bat house I made for him. Then maybe he will bring some friends to stay with him, or maybe move the rest of his family in with him.
Monya seems to be taking it well this year. Last summer she nearly freaked out about having rabies or something, until we did some research and found out that they don't really cause any problems at all, and they eat their weight in bugs each night.
What I find most interesting is that I can hold the camera right up to the glass and take a flash photo of him. That doesn't bother him in the least. He must be blind as a bat. Probably if the glass wasn't there he could hear me approaching and then he would fly away. This photo was taken through dual pane glass and an insect screen. Without the window glare captured by the camera you can see his claws and watch him wriggle and stretch his wings.

Graduation Party
Last week my nephew Ian graduated from high school so we hosted a celebration picnic at our house.
We had a graduation cake provided by The Frosting Angel featuring the Hazen High School colors of blue, green and yellow.
