PAINTED DESERT (3)

A shaft of light hits a big piece of petrified wood, while the shadow of the mountain behind me hides the surrounding area and makes the subject stand out.

So, how about the petrified wood in the National Park? In a nutshell, the process of per-mineralization of the wood was accomplished by silicification, meaning that the wood was replaced by silica long time ago. That’s interesting, but beside the scientific facts there are other reasons to point the lens at these gems in the desert.

Erosion produces the look how we can see the fossilized trunks in the park. Many are still buried under layers of soil and rock.

Different minerals have produced the colors we can find in the petrified wood today.

EDUCATIONAL VALUE

On the exhibition floor during DUBUQUE BALD EAGLE WATCH 2020

I have another photo of the Dubuque Bald Eagle Watch event from last Saturday for you. This picture tells a good story about the educational value the attendees were able to experience. The Jackson County Conservation had a turtle and this Milk Snake on display and visitors were able to touch or even handle them. Beside the birds of prey during the presentation of the University of Minnesota Raptor Center, this snake was the real star of the event. Many people came to see it and get a hands on experience with the harmless reptile. Not everybody was as brave as this little girl, who had no fear to pick up the snake and let it move around arms and fingers. I guess at the end of the day the snake was a little bit stressed but hopefully a lot more people had a new appreciation about some wildlife that surrounds us.

32ND ANNUAL BALD EAGLE WATCH IN DUBUQUE

Bald Eagle

Dubuque, Iowa had its 32nd annual BALD EAGLE WATCH in the Grand River Center yesterday. I was again a member of the team at the information table of the Dubuque Camera Club. All the local nature resource agencies and organizations were present with educational displays and information. I always enjoy networking with park rangers, other nature enthusiasts, and photographers and it was again a day well spent.

I told you in my last blog post about the snow storm that hit our area and big parts of the Midwest the day and night before. To my surprise the event on Saturday had a very good attendance, despite not so ideal road conditions. Many people of all ages came for the educational programs with live birds of prey.

American Kestrel

The young lady of the University of Minnesota Raptor Center (I’m sorry, I didn’t catch her name) did an awesome job educating the public about four different species of birds she brought with her to Dubuque. I think she answered every possible question that came up during her presentation and you could tell she had a lot of passion about these birds and how to care for them. Very enjoyable! All birds on display had an injury in the past and were unable to live in the wild on their own.

Red-tailed Hawk

The photography was again a bit of a challenge. Very little light in the conference room required very high ISO settings in camera. Flash is not an option with these birds of prey. The presenter moved around most of the time, so everybody in the audience was able to see them pretty good. On the down side it made it difficult to obtain focus and produce a sharp image. As during the last two years at this event I used it as an opportunity to practice handholding of the D750 with the Nikkor 70-200, f/4 attached. The number of misses was of course much higher than usual with this camera / lens combination out in the open country.

FIRST ONE OF 2020

National Mississippi River Museum and Aquarium, Dubuque, Iowa

I hope you were able to start the new year with something interesting and exciting. When our grandkids are in town a visit of the National Mississippi River Museum and Aquarium in Dubuque, Iowa is always on the agenda. It is one of the best places for education and entertainment, and this is valid for every age.

This first photo of the year was made at 70 mm, 1/320 s, f/4, and ISO 6400 through the thick glass of one of the seawater aquariums. Not my usual kind of photography but it always powers me if light and colors have something to offer. I hope 2020 will be a good year for all of us. I look forward to see your pictures and share visual stories with you again.

OUR WOODPECKER TREE #1

Male Yellow-shafted Northern Flicker at “Woodpecker tree #1”

Nature is always in a state of change. We were out of town over the weekend and when we came home yesterday we found one of the elm trees in our front yard on the ground. We knew this would happen one of these days. The tree was heavily effected by the Dutch elm disease, had more and more bare branches every year, and eventually the roots died.

This elm was an important tree for my photography. I always called it “Woodpecker tree #1”. Its location was perfect for shooting six of the seven woodpecker species that spend time in our woods but many other birds used it as well for approaching the bird feeders in the front yard.

Well, it’s not the end of the world, although I’m a little sad. A young oak tree nearby is growing fast since a few years and may take over the role as the new “Woodpecker tree #1” 😊

AUTUMN IN MINNESOTA #13

Sunset at the St. Louis River, just outside of Duluth, Minnesota

Jay Cooke State Park was the last campsite for one night at the end of our journey through the Northwoods of Minnesota. We had some snow and rain during the trip and shooting pictures of fast flowing water just seems to be a logic consequence. Well, I love to make photos of creeks and rivers. It is never boring and always a challenge.

I have talked here in the blog some time ago about a technique to make these kind of pictures without the use of a neutral density filter. There are sometimes situations where combining multiple exposures in one image, right in camera, is a valid solution. In particular at narrow and busy places, like famous waterfalls, with lots of visitors. Observation decks for example often vibrate and make any effort with a long exposure useless.

For this photo things were just great. At this time of the year, mid October, the low sun covers the river and the surrounding rocks with warm light for quite some time before it disappears behind the trees. With the Nikon D750 on a solid tripod I used the BREAKTHROUGH X4, 6-stop ND filter in front of the Nikon Nikkor 70-200, f/4 lens. For the final image a 5 second exposure at f/18, ISO 100 was used. Sure, some people like to see the water even silkier, it’s an unfortunate trend at the moment, but the wild St. Louis River, with its waterfalls and cascades, is not smooth at all at this place. The story of that evening was the combination of soft and warm light with the fast flow and turbulences of the river. If weather allows Joan and I will be back in the Duluth area very soon. Can you sense my excitement…? 😊

AUTUMN IN MINNESOTA #9

Looking out the window and seeing the snow that came down last night makes me want to think about something different. This was already the fourth time this season and with temperatures forecasted at -15º C (5º F) for tonight, it is a save bet to say, winter has arrived. About a month ago, back in Itasca State Park, Minnesota, fall colors were at their best. Alright, let’s wallow a little bit with those colors for now…

AUTUMN IN MINNESOTA #4

Mississippi River, only a few yards after the headwaters

Itasca State Park is the oldest state park in Minnesota, established 1891, and was created to protect the forest and waters around the headwaters of the Mississippi River. Its landscape was shaped by glaciers and it contains over 100 lakes and large tracks of Minnesota’s remaining old-growth red and white pine forest. It is a fantastic place to be in the fall, not just for photography.

Here is it where it all starts. The water from Lake Itasca flows over a simple rock barrier and the Mississippi River starts its 2,552 mile (4107 km) journey to the Gulf of Mexico.

The polarizing filter in front of the Nikkor 70-200 eliminates some of the glare on the water and led to a four second exposure at f/18. Enough to indicate the flow of the water with a silky look.

Stand of tamaracks, Lake Itasca, Minnesota

Itasca has beautiful red and white pines, spruce, fir, birch, aspen, maple, and others, but beside the colorful leaves one particular tree tells the story of fall the best. Larix laricina, better known as tamarack (German: Lärche), is a deciduous conifer. Its needles turn bright yellow in autumn and tell the story about the changing season. We found them at many locations in northern Minnesota during our trip. 

All three photos were made at or around the headwaters of the Mississippi River.

EARLY SNOW

Gorgeous light shortly after sunrise but most of the snow melted away during the day.

What’s going on? We still have daylight savings time (Sommerzeit) but last night a few hours of snow fall changed everything. It’s the first snow of the season for our woods here in eastern Iowa, but up in northern Minnesota Joan and I had already a white morning earlier this month.

AUTUMN IN MINNESOTA #3

Fall colors, Itasca State Park, Minnesota

When you go in October to the Northwoods the colors of autumn will probably be on your mind. We definitely wanted to be amongst the leaves and suck up every drop of light pouring through them. Two ingredients, a wet spring and a cold snap, are necessary for a good fall color show. When we left Iowa it was very warm but we were hoping to find colors further north in Minnesota.

Already at our second camp, in Itasca State Park, we found what we were looking for. Fall is a great time at Lake Itasca, at the headwaters of the Mississippi River (more about this in a later post). We hit the peak, while later, further north, more trees had already lost their leaves. I hope you enjoy this photo and some more that will follow in the next time…

 

FALL LIGHT, UNBEATABLE…

Bankston County Park, Middle Fork Little Maquoketa River, Iowa

It’s definitely fall, the leaves started to come down, but we don’t have really the fall colors yet. It needs a cold snap to make that happen but at the other hand we are not unhappy that temperatures are still in the “summer range”.

I love autumn, its colors, and the quality of light that follows the haze of summer days. Bankston County Park is located in a lovely valley along the Middle Fork Little Maquoketa River and was the destination for a short hike with the dog this evening. Every location where the rocks are exposed here in eastern Iowa reminds us that this was once just the bottom of a shallow sea millions of years ago. Just before the sun disappeared behind the ridge a shaft of “killer light” hit the layered rocks on the other side of the small river.

I underexposed by 2/3 of a stop. This hides some of the debris from recent flooding and brings out the colors of the rocks. An easy click that put a smile in my face…

COLLECTING FOSSILS (YEP, LEGALLY!)

If you look at the second photo first, I don’t blame you if you ask me, have you been back in Badlands National Park, South Dakota again? No, not at all. Joan and I stopped on our way home from Pilot Knob State Park last Monday at the incredible Fossil & Prairie Park Preserve in Floyd County, Iowa, located just a few miles west of Rockford, Iowa. The park includes an abandoned shale pit, preserved kilns, and a large area of native prairie. Our time was limited and so we just explored the former shale pit.

Shale pit at Fossil & Prairie Park Preserve, Rockford, Iowa

The rocks in the park are Devonian formations and about 375 million years old. At that time Iowa was still located near the equator and seas covered most of the land. As a result we can find many small fossils between the relatively soft limestones and shales. And here is the cool thing, fossil collecting is encouraged within the park. And that’s what we did and enjoyed (beside making a few clicks with the camera). I found mostly Brachiopods as you can see in the first photo, but Joan had also some Gastropods, little snails that scavenged the ancient sea floor.

If fossils and rocks are not “your thing”, well, the native prairie area with some wetlands and a pond looked very promising. Unfortunately time was too short to explore all of it, but we definitely “bookmarked” this area in our brains for another visit sometime.

RESTORED PRAIRIE

Three photos from our hike through Proving Grounds Recreation Area near Dubuque yesterday evening. I don’t know how this all looked when it was still a testing ground for excavators, bulldozers, and other heavy duty machinery built by John Deere Works, but the open areas have been nicely restored as a prairie and the variety of wildflowers, grasses, and other plants is really great. John Deere Works donated this land to the Dubuque County Conservation Board in 2018.

It was a little windy, which was good for keeping the mosquitos down in the grass, but less helpful for closeup photography of insects or wildflowers. Nevertheless, a few sharp pictures emerged.

NATURE CLICKS #434 - TIGER SWALLOWTAILS

Male Tiger Swallowtail, Little Maquoketa River Valley, Iowa

It has been a good year so far with the butterfly population in our woods here on top of the bluffs above the Little Maquoketa River Valley. We see a nice variety and overall numbers are better than during some other years. The stars of the bunch are always the three different species of swallowtails.

Female Tiger Swallowtail, black form

Friday night I saw a male Tiger Swallowtail interacting with another black looking swallowtail. First I thought he was fighting with a Black Swallowtail, a species we see here as well, but after it landed on one off our house plants it became clear that it was a female Tiger Swallowtail. I guess love was in the air. Males are always yellow while the females can be yellow or black. The yellow form is pretty common while black females are found more southwards according to my books. The last time I had one in front of the lens was 2015.

Both photos were made with the long lens at 600 mm (SIGMA 150-600 Sport), because I was actually on the hunt for hummingbirds. Like with my other wildlife photography I prefer to make an environmental portrait. Though I feel it is not so important to count every little hair, the insect still has to be sharp.
