Moonbow in Upper Mesa Falls, Mesa Falls Scenic Byway, Caribou-Targhee National Forest, Idaho
After our successful photo trip to Shoshone Falls to see a moonbow in its mist (see the previous post), we headed to the Mesa Falls Scenic Byway to see if we could photograph a moonbow in Upper Mesa Falls along the Mesa Falls Scenic Byway in the Caribou-Targhee National Forest in eastern Idaho. We had heard from a forest supervisor about a year ago that she already knew that someone had photographed a moonbow in Upper Mesa Falls, so we knew it could happen.
We hadn't modeled the terrain and moon's path ahead of time, so we didn't know where the best vantage point was or when it might happen. We headed to the main observation platform the night of the full moon, Monday, July 3rd. The moon was rising behind a cloud bank along the eastern horizon. As soon as the moon cleared the clouds, its light shot up the canyon making the whole streamcourse glow up to and beyond the Upper Mesa Falls. We saw this moonbow almost as soon as the moonlight set the canyon aglow around midnight. It appeared fairly close to the waterfall itself and progressed toward the waterfall as the moon rose. It soon seemed that the moonbow would be drowned out by the waterfall itself.
We moved to another observation platform to our left and caught sight of another moonbow and watched it as it progressed to the right, toward the waterfall, just like the previous one had done. We left around 2 AM with that moonbow still visible, but getting very close to the waterfall and we presumed that it was about to disappear.
The photo above is of that initial moonbow sighting and is a vertical in order to show the stars in the sky to prove that it was taken at night.

Phantom Fall with rainbow, North Table Mountain Ecological Reserve, California
Phantom Fall gets its name because it's seasonal and might not appear at all in dry years. We hiked out to see it the first week of April in 2023. We arrived just at the right time to see this rainbow form in its mist. The North Table Mountain Ecological Reserve, where the fall is located, is north of Oroville, California. The reserve protects a volcanic tableland that is level for the most part, but streams cut deep gorges in some parts. The water drops along the rock wall, then free falls in front of an alcove. There's a steep trail down to the base of the fall and we saw people walking behind the water.

Ravine Falls, North Table Mountain Ecological Reserve, near Oroville, California
A followup to our previous posting. We went back to the North Table Mountain Ecological Reserve on April 5th, 2023 to take in the wildflowers as well as visiting Ravine and Phantom Falls again.
In January 2023 California was hit with a series of storms and it has been in the media that the seasonal waterfalls at the North Table Mountain Ecological Reserve in northern California were flush with water. This reserve is northeast of Oroville, California.

Rainbow Fall, Devils Postpile NM, taken at night
During a July visit to Devil's Postpile National Monument, Rick visited Rainbow Fall at night to see if he could get moonlit shots of the waterfall. Except for the top quarter, the rest of the fall was in moonshadow. The shadows of the trees along the left wall are from moonlight. You can see stars in the sky. Using a very bright flashlight, he lit the water during a long exposure and got this image.

Burney Falls, after midnight, light painting
Burney Falls is a waterfall famous for its unique geology. The stream, Burney Creek, flows over the brink after being split into two streams that fall to the pool below. The rest of the cliff face has springs gushing from it that make it look like a very wide waterfall. The estimated amount of water flowing from this cliff is 100 million gallons per day. We visited McArthur-Burney Falls State Park during spring break 2021.
In a way, Burney Falls is challenging to photograph in that it is north-facing and doesn't receive direct sunlight. We managed to get a better image of the falls than usual by taking this picture after midnight and using a flashlight combined with a long exposure time to light the scene in a way that couldn't happen during the daytime. This image was actually taken around 12:43am with a 30-second exposure, ISO 800, f5.6, and a focal length of 18mm. It needed a wide-angle setting on the lens to get all of the falls in the frame, plus we wanted to be physically closer so the flashlight could be more effective. This process of using a flashlight (or torch as the British call it) to light the scene is called light painting. It appears to bring out the colors of the ferns better than a daytime photo when the cliff is in shadow.

Illilouette Fall as seen from Sierra Point in Yosemite National Park
This is a view of Illilouette Fall from the Sierra Point viewpoint in Yosemite National Park. See our YouTube video about Sierra Point and how to get there. You can also get a similar view of this waterfall from the Mist Trail hiking from the Happy Isles Nature Center to Vernal Falls.
The canyon that this waterfall falls into runs roughly south to north and is a relatively short boulder-strewn gorge before Illilouette Creek flows into the Merced River after that river flows over Nevada and Vernal Falls. This photo was taken in June 2016 when snowmelt had swollen the creek's flow.
Remember, it's a story, not just a picture.

Yosemite Falls on a sunny day in February, 2020
Here's Yosemite Falls on a sunny day in February, 2020. The winter season is shaping up to be another dry one, unfortunately. Yosemite Falls can be viewed from Cooks Meadow. The spot I, Rick, chose in the meadow allows for a clear view of the upper and lower falls. The trees at the bottom block your view of the water except at this spot. There's a little used climb to the top of the lower falls along the level ledge with some trees to the right of the lower falls. As I was setting up for this shot, I saw some one or a small group of people moving at the left edge of that ledge. It made me feel like trying it myself sometime. Also, Alex Honnold was on that ledge during the "Free Solo" movie.

Cave Falls from downstream, southeastern corner of Yellowstone National Park
We finally visited the harder-to-get-to southeastern corner of Yellowstone National Park known as the Bechler Region in August 2019. Because of the many waterfalls and cascades in this corner of Yellowstone, it's also called Cascade Corner.
The highlight for us was visiting Cave Falls along the Fall River. We posted an image earlier of the view of Cave Falls from the brink. This view is from downstream. The boulders on the left margin just below the falls are from the collapse of the alcove that gave Cave Falls its name. So, these falls got its name from an alcove and not a true cave. The characteristic that distinguishes this waterfall is that they are the widest waterfall of all of Yellowstone's many waterfalls at 250 feet across.

Grizzly Creek in Kings Canyon, 3 merged images
On the way to Kings Canyon National Park through the National Forest part of the Kings Canyon, we stopped off Highway 180 to look at Grizzly Creek Falls. You can hear it and see parts of it from the road, but the closer look is clearly better. From the trail I took, I had to cross the creek to get this full top-to-bottom view of the fall. It's on the north side of the Kings River and has a small parking area travelers can use to park their cars clear of the main road. It's only about another mile (1.6 km) to the boundary of Kings Canyon NP approaching the Cedar Grove area.
This image is the result of merging 3 separate images together. I took photos of the upper, middle, and lower part of the fall in order to get more detail and because I couldn't the entire waterfall in one shot since I was so close.

Roaring River Fall, in Kings Canyon NP, plus a huge boulder
In Kings Canyon National Park, there aren't as many waterfalls as in Yosemite Valley, but this one is in a special setting. Roaring River Fall gets its name because of how loud the water is as it drops down the canyon. The shape of the canyon at this point actually helps to amplify the sound. Also in this image is a huge erratic boulder that was left behind after the glaciers melted during the last ice age. You can get to this feature by parking along the main road and walking a short distance. During the spring, you'll be able to hear it. This image was taken in September after a very wet winter earlier in the year. So there was still a lot of water in the river. During the spring, though, the water can be as high as the whitish line of the rock face that you can see to the right of the waterfall.

Cave Falls in southwestern Yellowstone, long exposure.
We visited the southwestern corner of Yellowstone for the first time in early August 2019. The highlight of the visit to this part of the park called the Bechler Region was Cave Falls. It's also called the Cascade Corner because of the great number of cascades and waterfalls. The river that forms these falls is the Falls River. You can guess why. This is the least developed part of Yellowstone and requires driving on dirt roads to reach.
Even though this waterfall is only thought to be 20 feet high, we've read that it's considered to be the widest of all the waterfalls in Yellowstone at 250 feet.
This photo was from the established overlook for visitors. The "cave" that gave the falls its name was actually an alcove, the roof of which has collapsed. The boulder field from that collapse is visible in the right middle of this image. This boulder field is now marked as off-limits by the park in case additional rocks collapse onto the pile.
We visited the Bechler Region at the end of our trip to see the Steamboat Geyser erupt, so, after visiting Yellowstone for a few decades, we still got to experience things there that we had never experienced before.

Silver Strand Fall in Yosemite Valley's west end, above Tunnel View

One of the famous viewpoints in the world is the Tunnel View in Yosemite National Park. If you're at this view point earlier in the year, spring and early summer, you should also make a point of turning to your right (south) and looking for this waterfall, Silver Strand Fall. It drops about 574 feet (175 m), according to the wikipedia entry, though the topographic map shows it as 400 ft (123m). The creek flows under the road farther downhill and eventually joins the Merced River. Since it's fed by melting snow, it's usually gone by midsummer, but this year, 2019, was an especially wet year in California, so it was still flowing well in mid-June, when this picture was taken.
It's easy for people to get caught up in looking at the Valley, but with a little extra looking around, you can find this gem.

Little Gibbon Falls, in Yellowstone NP, along the Gibbon River
We were hiking out from Wolf Lake in Yellowstone and saw a sign for a side trail to Little Gibbon Falls, along the Gibbon River. We figured it would be worth the time to go take a look and we weren't disappointed. This image is the view from the trail, which has a steep dropoff in this area. The water falls over rocks that have a stair-step pattern, which matches the sedimentary rock layers in the cliff face next to them.
We spent quite a bit of time here and were joined by dayhikers. We discovered from the map, that this waterfall is only about two miles from the road. But we were approaching it from the wilderness area, having backpacked in to Wolf Lake the night before. We also realized that we could've hike in to Wolf Lake from the main road on this trail and would've had less distance to cover. Backpacking in from the Ice Lake trailhead was a little bit longer. Something to keep in mind for next time!

Cascade along Grouse Lake Creek in Yosemite's backcountry, Wawona area
On the second night of a three-day backpacking loop trip in the backcountry of southern Yosemite National Park, we camped near this cascade along a tributary of Chilnualna Creek. This tributary flows out of Grouse Lake. This was just a hint of what was ahead of us as we looped back to Wawona and followed Chilnualna Creek back down the slope. Chilnualna Creek forms a number of cascades and waterfalls before forming the biggest drop Chilnualna Falls, a 240 foot drop into a cataract.
We enjoyed this little cascade as our dining spot not far from where we camped in our hammocks. Getting an image with the feathery effect is accomplished by using a slow shutter speed. The shutter speed for this image was 2 seconds with an ISO of 50 and f/stop of 22.

Granite arch in Yosemite, along Chilnualna Creek, Wawona area
This was the third day of a loop backpacking trip we took along the Alder Creek trail and looping clockwise to come out by the Chilnualna Falls and cascades, which are dramatic in their own right. We really took our time in this area, almost 4 hours, before heading down the trail which loses about 2000 feet (610 meters) in elevation to the trailhead where we parked the car.
