Water ouzel (dipper) in Silver Creek, Alpine County, California

 



Over the Labor Day weekend, we went to Alpine County, California, an area where Rick worked in the Toiyabe National Forest on the trail crew. There was a fire south of us in Slinkard Valley, so we couldn't stay overnight, but we did get a chance to look at the east fork Carson River where Silver Creek joins it. We found this water ouzel (dipper) bird that lives along river rapids and eats insects that live in the rapids. I happened to catch this image of the bird with an insect in its mouth. This species of bird walks around in the rapids with no apparent concern for its safety. It can even dip underwater when looking for its food and walk on the river bottom. We've even seen these birds dipping into the Merced River in Yosemite, during the winter. It doesn't get cold because it has so much oil in its feathers, it doesn't get wet.

Upper end of Yosemite Valley from the Four Mile Trail, July 22, 2020

 



Here's a photo taken in Yosemite National Park showing Tenaya Canyon to the left and the Merced River Canyon to the right with Half Dome in the center. On the right, you can see Vernal Fall and Nevada Fall. Rick took this photo from the Four Mile Trail during what he calls his "Overnight Day Trip." He was able to get to Yosemite from Fresno by taking the YARTS bus. He didn't have the chance to get a day-use permit or an overnight permit, but you can still get into Yosemite if you arrive on the YARTS bus. The Four Mile Trail to Glacier Point is actually about 4 and a half miles long. The view opens up to the east after 3 to 4 miles up what is a relentlessly uphill climb. This was Rick's first time on this trail despite all the times he's been to Yosemite over the years (more than 180 visits). He expects to hike this trail again soon. He accidentally got his shadow in the picture at the lower right. It was after 6 pm and the sun was getting low enough in the sky to make that happen.

This image is the result of two images being merged together. Each image was taken with a Motorola z4 smartphone, merged, and then processed for brightness and contrast in Digikam on a Linux computer.

Comet NEOWISE over Old Sacramento, California




It might be hard to make out in the first photo, but Comet NEOWISE is in the right upper center of this image between the building and the flag pole on the bow of the riverboat. This image is from Old Sacramento State Historic Park in Sacramento, California. The riverboat in the foreground is the Delta King, which acts as a floating hotel and is permanently moored at its dock. The building in this image is on the other side of the Sacramento River in West Sacramento.

Bob took these photos on the evening of July 17, 2020.  In the first photo the lights on the riverboat were so bright that it produced a sharp contrast with the night sky where the comet was.  To reduce the contrast he used a graduated neutral density filter to tone down the riverboat lights.

The second photo is a zoom-in showing the comet and its position relative to the building in the first photo.

Comet NeEOWISE and the Big Dipper over Yosemite Valley



Here's a photo showing a slowly fading Comet NEOWISE C/2020 f3 below the Big Dipper. I was in Yosemite on the south rim next to Sentinel Creek with a clear view of the sky. I was hoping to get a view of the comet floating above El Capitan, but the moon was just past new and was setting so there was no light for the landscape. So I turned my attention to getting pictures of the comet with the Big Dipper so it would have recognizable stars around it. It's above two stars in the constellation Leo Minor. It's closest to the earth on this night, but farther from the sun so it's not as brighter as before.

ISO 6400, 30-second exposure, f4, focal length 20mm. This image was cropped to high light the constellation and comet below.

Comet NEOWISE over Sacramento, California






These photos are of Comet NEOWISE, aka C/2020 F3, taken at about 4:39 AM Sacramento time on July 12, 2020. I, Bob, had driven to the west end of the Yolo Bypass, which is between the cities of West Sacramento and Davis, California. I was looking northeasterly when I took this shot.  Other photographers were out in these predawn hours to get photos of it, like I was. The horizon is the Sierra foothills.

At this point Comet NEOWISE is on the outbound part of its orbit after already whipping past the sun. The tails of comets are created by and directed by solar radiation, which means they always point away from the sun. The sun is below the horizon in this view and the tail is pointing away from it.

While I was getting shots of the comet, a freight train passed by me on the nearby tracks.

Great Fountain Geyser and forest fire smoke, Yellowstone National Park, Wyoming



This is a photo of the Great Fountain Geyser along the Firehole Lake Drive in Yellowstone National Park. This was taken on August 15, 2016 while a forest fire was raging on the horizon.  The smoke extends from the setting sun to the upper right corner.

Great Fountain Geyser is one of the geysers that the rangers can predict when it will erupt, but the window of time that it might erupt is plus or minus two hours. When it's building toward an eruption, the vent and surrounding terraces will fill with water to overflowing and the column of water will shoot up out of the pooling water, as opposed to geysers like Old Faithful Geyser that erupt out of a cone.

Remember, it's not just a picture, it's a story.

Female common mergansers resting on a log, American River Parkway, Sacramento, California



We were out paddling around the American River Parkway in Sacramento, California when we encountered these female common mergansers resting on this log that had fallen across this channel.  This is just downstream from the Watt Avenue Bridge.

The merganser in the middle had its mouth open, while the merganser on the right was giving us the eye while trying to get some sleep.  Mergansers are also known as fish ducks, since they feed on small fish by diving underwater and swimming after their prey.

Grotto Geyser erupting, Yellowstone National Park




Grotto Geyser always makes me think of a sea turtle.  If you imagine the rounded feature in the middle as the turtle's head, then the other two rounded features on either side look like flippers. Grotto Geyser is in the Upper Geyser Basin, which includes Old Faithful Geyser, in Yellowstone National Park.

Grotto may actually be a unique example of natural arch formation.  Scientists believe that the two "flippers" may have been formed by geyser mineral deposits over tree trunks which created two arches, since each flipper is an arc of rock over openings.

Half Dome at sunset with a bright moon in front of its face



Here's a full moon rising next to Half Dome, Yosemite National Park. I, Rick, was actually leaving Yosemite after a day visit and decided to stop at the Tunnel View for one last look at the valley. Some people off to the left were pointing somewhat excitedly, but I couldn't figure out why, at first. Then I saw the moon rising, so I rushed to a spot where I could get the best angle. The red light of the setting sun contrasted well with the bright moon.

I did some adjusting of brightness and contrast and worked specifically on the area within the moon to bring out the details, but nothing was repositioned or added to the image.

Delicate Arch and a sandstone amphitheater, Arches National Park, Utah


Delicate Arch in Arches National Park, Utah sits on the rim of an amphitheater.  This panoramic shot shows that amphitheater plus Delicate Arch.  This arch is at the end of a trail that makes for a 3 mile round trip hike and gains 480 feet from the trailhead to the arch.

Delicate Arch is the symbol of Arches National Park and is such an iconic symbol of Utah that it appears on many of the state's vehicle license plates.

We visited Delicate Arch during a spring break in 2017 and hiked almost all the way around the rim of this amphitheater to get this shot.  This panorama is a combination of 18 bracketed images.

Yosemite Falls with a moonbow in the lower fall, Yosemite Nat'l Park


This image of Yosemite Falls, with the upper and lower fall visible, is lit up by moonlight. You can see stars in the sky above the falls. The rainbow in the mist of the lower falls is caused by moonlight, not sunlight. When we viewed this scene with our own eyes, we couldn't see the colors, but the camera picks them through a long exposure of 30 seconds, ISO 800. We were just at the falls getting moonbow pictures in the lower fall, but as we were leaving, we decided to look back at the whole waterfall and see if the moonbow was visible from this other perspective.

This natural event can happen 2-3 days around the full moon in the spring and early summer in Yosemite Valley, especially when there's enough water flow.

Half Dome from the Merced River After Passing Under Sentinel Bridge


I, Rick, used to have an inflatable kayak. In January 1997, Yosemite experienced record flooding. People were trapped inside the valley due to the floodwater. A few months later, in May, I took my inflatable kayak on the shuttle bus and traveled as far upstream as the bus would take me, Happy Isles. Then I carried my kayak to the shore of the Merced River and inflated it. I shoved off and traveled downstream to view some of the damage caused by the flooding, including picnic tables in the middle of the river. Along the way, I passed under Sentinel Bridge and looked back at Half Dome. A lot of people like to get a picture of Half Dome from the bridge, but here I had the opportunity to include the bridge in the picture. That was the first and so far only time I've paddled on the Merced River. Must do that again soon.

Half Dome approach from the east


Here's Bob posing at the western end of the Sub Dome before we start on our way up to the top of Half Dome. You can see the famous cables going up the eastern side of Half Dome that give people a secure way to make it to the top. From this side of Half Dome, you can clearly see the way that granite erodes. The process is called exfoliation, which means that granite slabs flake off and eventually fall down the cliff.

Bob and I backpacked into the Little Yosemite Valley the day before, then finished the trip to the top on this day. Before hiking to the top of Half Dome, you have to climb to the top of the Sub Dome, which is very steep and a little scary. Then you drop down a little bit to a notch between the two domes. That's the spot behind Bob, where a couple of people are walking. Farther along, you reach the base of the cables. Sometimes, the Park Service leaves a basket full of gloves for hikers to use if they didn't bring their own. You can see people about half way up to the top, using the cables to make the ascent.
