Valley Oak at sunset, North Table Mountain Ecological Reserve, near Oroville, California
After an afternoon of hiking in the North Table Mountain Ecological Reserve, near Oroville in northern California, we got back to our vehicle at sunset. Right next to the parking area was this beautiful valley oak, making a silhouette against the bright horizon. We've heard about this place for many years, but this was our first visit and it won't be our last. This visit was in January, so we plan to go back later in the spring when the wildflowers are in bloom.

El Capitan just after sunset, Yosemite National Park, California
El Capitan reflected in the Merced River in Yosemite Valley, Yosemite National Park. This picture was taken just after sunset with calm winds. We spent the afternoon cross-country skiing out of Badger Pass and went through part of the valley on our way out of the park. Right now, everyone has to leave the park by 5PM.
Settings were f1.7, 1/33 sec, ISO 244, 4.74mm, in a Motorola z4 smartphone.

Sunset in Yellowstone, lighting up Clepsydra Geyser
We arrived in Yellowstone on our 2019 trip around sunset. After setting up camp at the Madison Campground, we went to the Lower Geyser Basin, a.k.a. the Fountain Paint Pots, to look around before it got dark. We got to see Clepsydra Geyser in its nearly continuous state of eruption as the sun was turning red on the horizon. Clouds floating overhead helped reflect some of the sunlight back down. The way the western clouds were shaped made the fiery colors take on the shape of two prongs or maybe a duck. At least that's what it made me, Rick, think of. At this stop along the park road, this feature is the farthest out on the boardwalk.

Yosemite firefall with avalanche, El Capitan and Horsetail Falls
Yosemite has become famous for what's called the firefall effect. In mid to late February the setting sun's last rays of light turn red and shine on the eastern flank of El Capitan right on a spot where an ephemeral waterfall is flowing, provided there's enough runoff from its small 40-acre watershed. Of course, the effect also requires a clear horizon in the West.
This image, taken on February 16, 2019, shows the spot on El Capitan where the setting sun's reddening light shines during this time of year. Although the Horsetail Falls' watershed had lots of snow in it, the weather had been cold enough that not a lot of it was melting off and flowing into the waterfall. Some water was flowing in the fall, but there were also some spots where snow and ice was stuck on this cliff and would occasionally break off and avalanche. In the vertical stripe of red above, the separate dash of red on the right near the bottom is actually an avalanche catching the setting sun's burning light.
We didn't catch this image with our still cameras. This is actually a still frame from the video we shot of the firefall. We didn't see this avalanche when it happened, but we saw it on our video clips after we left. From our spot on the south side of the Merced River, we could hear an occasional avalanche, but by the time we heard them, they were done with, since the sound took so long to reach us.

Pigeon Point Lighthouse and beach
The Pigeon Point Lighthouse is fifty miles south of San Francisco along the central California coast near the town of Pescadero. At 115 feet tall, it's one of the tallest lighthouses in America. It was first lit in 1872 and, although the lighthouse tower is no longer active, the point is still an active Coast Guard station.
The lighthouse is in need of restoration and has been closed since 2001 when pieces of the brickwork near the top fell off. The grounds are still open, but the area around the base of the tower is fenced off. The park used to have an annual lighting of the historic lighthouse event in November to commemorate when the lighthouse was first lit, but discontinued the lighting in 2011. The historic lighting may resume after the restoration project on the tower is completed. The 2000 pound first order Fresnel lens that sat atop the tower and cast the lighthouse's light out to the sea is now sitting in the fog signal building. It's 16 feet tall, 6 feet in diameter, and consists of 1008 prisms fastened to a brass framework.
Bob took these photos of the lighthouse in 2010 on the day of the historic lighting event and posted his night time shot of the lighthouse lit up in an earlier posting.

El Capitan facing the sunset, Yosemite National Park
As a winter storm was clearing over the Sierra Nevada, in Yosemite National Park, the massive El Capitan faces the setting sun. This time of year, may people visit Yosemite in order to see the "firefall" of the red light of the setting sun causing the the waters of Horsetail Fall to glow and appear to be on fire. Unfortunately, there's no water in the waterfall this year due to a very dry winter. So in this image, we decided we should concentrate on El Capitan and the dramatic-looking sunset. We set ourselves up along the Four-Mile Trail on Yosemite Valley's south side for this picture. We had to leave the trail and go up a little bit of the slope to get a clear view.
This view might also illustrate why Horsetail Fall is a temporary waterfall. The drainage basin that supplies the water for the fall is just the eastern slope of El Capitan. You can see that basin at the upper right of this picture. So without much rainfall or melting snow to feed it, there is no waterfall.

Early Evening Sun with Smoke-filled sky near Canyon Village, Yellowstone National Park
This is the sun a short time before sunset near Canyon Village in Yellowstone National Park. A forest fire was raging north of the Madison River to the northwest from this spot and the smoke bloodied the sky.
We photographed this scene on August 16, 2016. During the day, we had driven along the Madison River and saw where the smoke was coming from, the Maple Fire which was caused by lightning.

Half Dome at sunset in Yosemite Valley
Sunset at Yosemite Valley with the magnificent Half Dome as the main subject. There's North Dome at the left in this view. We've posted a photo of Half Dome as seen from the top of North Dome in an earlier section of our blog. We've been to the top of Half Dome three times, and Rick has been to the top of North Dome twice. One thing about the angle that Half Dome's face has in relation to the sun is that it is very often in shadow in the morning and isn't fully lit until the afternoon. There are now people hiking to the top of Half Dome at all hours of the day. We've met people started their hike to the top of Half Dome late at night because they wanted to witness the sunrise from the top the next morning.
Camera settings were 1/125 sec. f/5.6, ISO 100, 32 mm focal length.

Rays of Light From the Setting Sun Create a Silver Lining in the Clouds Over the Teton Range, Wyoming
On August 10, 2016, we were in Grand Teton National Park. After spending some time photographing 4 bull moose along the Gros Ventre River, we drove north along the range and noticed that the sun was setting and creating a fringed look to the clouds. In this image, you can see the silhouette of the Teton range, parts of which still have snow. In the clouds, the lobes of the clouds were creating a light and dark pattern to the sunlight. The clouds themselves appeared to have a silver lining.
The image was taken with a Canon PowerShot SX530 HS, ISO 100, f8, 1/640 sec. zoomed at 65.4mm. Taken on August 10th, at 7:50PM from the Teton Park Road.

Sunset silhouette of the Teton Range in Grand Teton NP
A sunset profile of the Teton Range in Grand Teton National Park. The peak named Grand Teton is the highest peak, third from the right. The sun's rays are flaring over the southern end of the range. The highest peak under the rays is Buck Mountain and the canyon to the right that is the low point is Avalanche Canyon. The timing worked out for this image as Bob was driving back to camp and saw the effect the peaks were having on the light from the setting sun, so he used one of the turnouts along the main road through the park.

Point Bonita Lighthouse at sunset, San Francisco, CA
Two views of the Point Bonita Lighthouse at sunset. This lighthouse is in one of many units in the Golden Gate National Recreation Area in and around the San Francisco Bay area. This historic lighthouse is perched on a sea stack at the entrance to the Golden Gate and is still in operation. It requires a hike through a tunnel and over a bridge that looks like a miniature version of the Golden Gate Bridge to get to. These images show the sun setting over the Pacific Ocean and its light glinting in the lens of the lighthouse.
The lighthouse is only open to visitors this late in the day during Sunset/Full Moon guided tours given by the National Park Service.

Nearly full moon rising next to Half Dome, viewed from North Dome, July 11, 2014
After hiking about 4 and a half miles from Porcupine Flat to North Dome, I waited for the sun to set and the moon to rise. July 11th was the day before the full moon, so the scenery would still be lit by the sun, or at least still be bright, as the moon was rising. I had to reposition myself around North Dome until I saw the moon lined up the way I wanted it. I hoped to see the moon between Half Dome and the smaller high point to its left, called Sub Dome. Fortunately, that worked out. Then I hiked back out from 9PM to 11PM.
Getting the exposure on the moon and the landscape in the same image is very difficult. The moon at this phase is very bright, so a setting that properly exposes the landscape results in a washed-out moon. Properly exposing the moon results in a dark landscape with no detail. To solve this problem, you can take two images, one exposed for the landscape and the other exposed for the moon, then combine the moon from the one image into the washed-out moon in the other.
While atop North Dome, I decided to take a selfie with my smart phone as proof that I was there.

The picture shown below is the bench mark for the highest point of North Dome, at 7531 feet elevation. On topographic maps, you'll see these labeled as BM and a plus sign or crosshair on the map, so that when you see this marker on the land and find that mark on the map, you know exactly where you are.

Le Trois Teton - Grand, Middle, and South Teton as seen from Hurricane Pass, Grand Teton National Park, Wyoming.
In Grand Teton National Park, most visitors view the Teton Range from the east and look westward. In 1999, Bob and Rick backpacked nearly the length of the Teton Range on the west side. Along the way, we viewed the highest of the Teton Range: Grand, Middle, and South Teton to our east. Along this route, we crossed over Hurricane Pass in the afternoon and had the range illuminated from the west as we looked eastward.This trip took 5 days and we covered around 55 miles, ending at the Jackson Hole Resort and taking the tram down to the valley.

Bridalveil Falls and the Leaning Tower lit by the setting sun from across the Merced River, Yosemite National Park
On one of our trips to Yosemite, we were on the Northside Road heading out when we were struck by the light of the setting sun on the other side of the valley. The water of Bridalveil Falls glowed in the light of the setting sun, but the wall behind it appeared to be in shadow or was a darker granite. So the water really stood out from the wall during the brief time that the light came in at that angle. This image was taken in March, so there was still snow on the upper slopes. The Merced River was in shadow as well, so the brightly-lit cliff face and cloud are the brightest parts of the image. It has been cropped to an 8x10 ratio.

Sunset silhouette of Delicate Arch, Arches National Park, Utah
Delicate Arch is one of the most iconic of all the natural rock spans. It's not only the symbol of Arches National Park, but also appears on the license plates of many Utah motor vehicles. It was also shown on a postage stamp honoring Utah on the centennial of its statehood.
This photo shows the 65-foot tall arch in silhouette by the setting sun. It is one of the most visited arches in the park requiring only about a 2 mile hike to reach. It was formed out of Entrada sandstone and is a freestanding arch, which is what makes it so distinctive. To make it even more dramatic, it is also perched on the edge of a huge sandstone bowl on one side and a cliff on the other.

Sentinel Point, in Yosemite National Park, at sunset.
Sentinel Point towers over the south rim of Yosemite Valley. Not as famous as other features, like El Capitan or Half Dome, it can still offer some spectacular views. This image was taken as the sun was setting and Rick was looking for Horsetail Falls to the west of El Capitan picnic area. After gazing westward at the falls, Rick looked east and was surprised to see the moon rising near Sentinel Point, which is the left-most point of rock in this photo. The image was taken in February as the setting sun reflects from El Capitan's east flank, which only happens in November and February, each year. Because this was in February, you can see some patches of snow on the cliff.
So many people know about Horsetail Falls glowing red from the setting sun in February, that the Park Service has started closing off one lane for parking, so all the photographers can park and be close to the waterfall feature. We've tried several times to get Horsetail Falls lit up by the setting sun in February, but there are other features around Yosemite to keep an eye out for, so don't fixate on one thing to the exclusion of others.
