Five days after my eastern Sierra Nevada snowstorm photography road trip, I was back on the road for more fall leaf work but on the west side of the range. Weather forecasts for days ahead showed the southern tail end of a front primarily moving through the Northwest would provide a mostly cloudy day with light breezes on Wednesday, with some periods of minor rain that is necessary for my focus stack blending post-processing. Temperatures were expected to be relatively mild, so no threat of snow. This was to Calaveras Big Trees State Park, famous for its giant sequoia trees, which is our largest grove north of Kings Canyon. The park's main facilities are at the 4680 foot elevation along highway SR4, with the main fall leaf species, Pacific dogwood, which changes to a range of bright colors. So, a mid-forest elevation, a bit below average winter storm snow levels.
I have worked the park a few falls in the past; however, most of that work was early November view camera 4x5 film work, so it is not something I can add to my website since drum scanning is at least $80 a transparency. Thus, early Tuesday afternoon, October 21, 2025, well before commute traffic, I drove the 3+ hours and 160 miles to Calaveras Big Trees State Park. Paid for a $35 campsite at site #3 but would be sleeping comfortably in the back bed of my 2023 Trailblazer LS. I get plenty of tent time each year and prefer sleeping in the car during fall and winter. Had enough time to walk both the 1.5-mile North Grove Loop Trail, which showed my timing was perfect for peak Pacific dogwood, aka mountain dogwood, Cornus nuttallii, leaf color. In fact, dogwood fall leaf color was the best I've yet seen there. The official state park brochure webpage:

I also hiked the South Grove Trail that was a dozen miles away. That remote grove is supposed to have about 3000 big trees; however, most are scattered about landscapes beyond views from the trails or fire roads. With the long night hours at this time of year, I was asleep early during the evening. In the wee hours, looking out my window, I happily noted the stars had finally disappeared behind forecast moving clouds. During the night, I usually sleep for 1 to 3 hours at a stretch while dreaming 100% of the time. So I was awake early at dawn to set up my car and gear for a day of foul weather photography.

By 7:15am PST Wednesday afternoon October 22, 2025, I was working my first subject. I decided to start by taking the Overlook Grove Trail that provides better views down into the forest, versus the much more popular North Grove Loop Trail that is rather level, with incremental natural science information viewpoints. And at 7:33am PST, I worked the second subject shown above, a 3-column, 40-shot focus stack stitch blend using my Sigma 30mm prime at F5.0. Indeed, at least early, I had an optimal overcast sky plus dead calm. The above image shows the kind of colorful understory below most of the forest trees.
Unlike our related species, coastal redwoods, which tend to dominate their forests, giant sequoia, Sequoiadendron giganteum, grows scattered in mixed mid-elevation forests with many other species. In the above, besides 3 giant sequoias, are also sugar pine, Pinus lambertiana, ponderosa pine, Pinus ponderosa, and incense cedar, Calocedrus decurrens. Occasionally, the park, during especially cold fronts, receives snowfalls in early November, adding that aesthetic photography bonus. But by that time, the dogwood will be near its late leaf color stages, less colorful.

The next image above is a 3-column, 1-row, 3-frame 25-shot focus stack stitch blend that was shot at 7:55am PST. It also includes some white fir, Abies concolor, which, when young, makes ideal Christmas trees. Notice the sequoia has only a single branch showing within this frame, as limbs of mature trees tend to be up high, above the level of any past wildfires burning their understories. The park has done an excellent job using controlled burns to clear areas of the forest, especially around these large trees. To the right of the sequoia is a barkless snag and to its right, somewhat obscured, is another large sequoia.

Another perspective of the same sequoia shot at 7:58am PST. The other background sequoia is now more visible, as well as 2 others. The 2 trees at frame right are sugar pine, while the third tree is an incense cedar that has somewhat similar foliage and sometimes has a similar reddish-brown bark color. The way to tell the two apart is that the cedar's foliage is flat. Another smaller conifer species at the lower frame right edge is the uncommon Pacific yew that has red berries. Several may be found right beside the south section of the North Grove Trail.

The above is a single vertical frame shot at 8:19am PST that shows part of the North Grove Loop Trail above where it passes by two sequoias. A burnt sugar pine trunk is on the right side of the frame that was quite alive with foliage higher up. Note the yellow sap flowing down its trunk, which the fire caused. Given its thick bark, giant sequoias are among the most resistant to burning conifers. Looking at the enlarged vertical slice view, one can see some of its fallen pine cones, which are the largest in the world. The shrub with still very green leaves in the lower frame left foreground is also a dogwood, which shows the varied range in changing leaf color cycle even among near zone trees.
With many more good subjects on my list, a large area of blue sky, not in the forecast, ominously for my purposes, moved over the park. A minor breeze also developed that would crimp further work. After waiting a couple of hours at a particularly spectacular part of the grove with its largest group of big trees, I gave up and began driving home. But after just driving west about 8 miles, I had a better open view of the sky that showed the blue sky was just in this region, with clouds beyond in all directions. Given reception, I was also now able to use my old Moto G smartphone to look at weather sites that showed the blue sky would pass, with an afternoon that would cloud back up with some storms. Thus, turned around and drove back into the park. Modern electronic technology to the rescue! From there, I drove back out to the South Grove, where I explored some areas I had not yet seen, including the quite nice and fall-leaf-colorful Beaver Creek picnic area, which I'll highly recommend during fall. And indeed, by 11am clouds began moving in. Not only clouds, but I could hear plenty of thunder further east at higher elevations that were blanketed in stormy clouds.

The sequoias grow near the north rim of the North Fork of the Stanislaus River, which is 1000 feet lower at 3.6k feet. Another species with fall leaf color is black oaks, Quercus kelloggii. Leaves of most black oaks only change to yellow, while a few trees also sport oranges and reds. At 11:39am PST, I worked the above oak leaf color along the river. Because the park forest has been protected for many decades and never logged, its forest conifers are some of the largest in the range, as this view upriver readily shows. Looking at the enlarged vertical slice view, one can see a fisherman standing by a right-side river pool. And his partner's rod is that dark line across the nearby bright granite boulder. Because the slight breeze jostled the oak leaves, post-processing required about 6 hours of tedious manual Zerene Stacker work to fix the misregistrations. There are several fine subjects along the river I hope to work on in the future.

At midday at 1:09pm PST, as sprinkles enveloped the area while wearing rain gear, I worked parts of the North Grove Loop Trail. The above subject, using my 19mm lens, shows parts of the boardwalk in the area of the densest big trees in the grove. In the lower right of the frame are thimbleberry, Rubus parviflorus, whose fall leaves turn to a fine yellow and contain sparse, delicious red berries that taste a bit like raspberries. Beside my legs are some drying bracken fern, Pteridium aquilinum, that turn a light pastel yellow-brown. These well-constructed wood boardwalks cover short sections of the trail where water, during wetter times of year, covers expanses of this mid-forest elevation basin.

The above strong subject was one I had patiently waited near during the morning for at least an hour before giving up due to lack of clouds for diffuse skylight. But in the afternoon, between some significant showers that dropped about 1/3 inch of rain, at 1:37pm PST, I was back with my camera and able to capture, with my 30mm lens, the 3-column stitch blend of 38 focus shots. There was some breeze that caused enough misregistrations between focus stack shots that I spent about 5 hours tediously, manually fixing the result of dogwood leaf movement with Zerene Stacker. Time well spent with the bright dogwood leaf foreground in front of 9 giant sequoias in the background. Such dense groups of large sequoias are common in Sequoia National Park groves, far to the south but uncommon elsewhere in the north. The small conifer at the center-right of the frame bottom is a white fir. And to be clear, it is only when these forests are under this kind of diffuse cloud light that the color leaf undergrowth has such a magical quality. So no, don't visit during fall under much more common, harsh, contrasty, sunny conditions, as the photographic images do not lie.
At page top I worked my last subject at 2:05pm PST, the same large sequoia as 2 other shots above. To the left of the big tree, in the distance, one can see the distinctive crowns of 3 other sequoias. The small tree at frame lower right is a ponderosa pine, Pinus ponderosa, also called western yellow pine, that has been in several of the above frames. The large tree at frame left is a white fir. Behind the dead snag are several giant sequoias, and rising above each of those in the misty, cool, humid air is a sugar pine that shows some of its long, hanging pine cones.
Over the day, I had only had usable diffuse cloud skylight for a couple of hours, so I was frustrated leaving significant numbers of good subjects I just never had a chance for. But that just means I am certain to return during some future fall.
On the periphery of a storm further north, given diffuse cloud sky light and near-calm breezes, late morning Wednesday, November 12, 2025, I visited Stevens Creek County Park, which is only 8 miles from where I live, for fall leaf work along Stevens Creek. That was primarily bigleaf maple trees, whose leaves are the only common coastal region tree species with prominent fall leaf color. The young, relatively low Santa Cruz Mountains only rise to a bit above 3000 feet, but because of orographic rainfall from the adjacent Pacific Ocean, they receive considerably more rainfall than near sea-level San Francisco Bay urban areas, which supports cool, shady, mixed woodland and redwood forests. Areas east of the shielding range crest like this are much less foggy.

At this fall time of year along coastal California mountains, many deciduous trees entering dormancy have lost their leaves while herbs' above-ground growth has died away, drying. Balancing that loss of green, especially close to streams and in shady northern exposures, are mosses, fungi, and small annual herbs rising from seed. This creates a more visually open woodland forest, with dense areas of bare branches. Although I identify some plant species in the text below, there are other herbs and shrubs in each image I have not yet been able to that is primarily a matter of leaf shapes and arrangements. Our coastal region also has over 100 species of bryophytes that include mosses and over 700 species of fungi that require considerable training to identify.

A bit before noon, I worked on this first modest subject above, a 2-column, 2-row, 4-frame stitch blend of 48 focus stacked shots. Stevens Creek, with a small bigleaf maple, Acer macrophyllum tree and many of its fallen, drying, turned orange-brown leaves below. Also in the background are tanbark oak, Notholithocarpus densiflorus, and California bay laurel, Umbellularia californica. In the foreground, lower right, are coastal wood fern, Dryopteris arguta, and moss-covered rocks with a fallen branch with greenshield lichen, Flavoparmelia caperata. In the background are blackberry, Rubus sp., which are common everywhere along the stream. Note how the fallen dry bigleaf maple leaves are a more aesthetic orange-brown instead of a boring dry brown that most plant leaves become. Stream rocks are sedimentary sandstone and mudstone, often with a darker, dried organic surface. This type of complex winter woodland subject works best using a camera/lens system capable of great detail.

My second subject above, also a 2-column by 2-row 4-frame stitch blend of 7300 by 9400 pixels, was the strongest image of the day with bigleaf maple leaves at peak fall color. In the foreground are blackberries. The left-of-center moss-covered tree, showing a few green leaves at the top, is a box elder, Acer negundo, and the tree with mushrooms and fungi is probably too. That fast-growing, easily attacked by fungi, species only lives for about 75 years maximum. Also at frame top are leaves of an evergreen California bay laurel whose strong leaf fragrance tends to dominate these landscapes. At frame right above the stream are dense, bare tangled branches of a California buckeye, Aesculus californica, with a few of its buckeye fruiting balls still showing.

Another Stevens Creek subject with bigleaf maple, California bay laurel, blackberry, thimbleberry, Rubus parviflorus, and snowberry, Symphoricarpos albus. Again, most fallen leaves are from bigleaf maples. The box elder at frame right center has coastal wood ferns growing out of its trunk, which is common. Notice how smooth boulders within the stream channel lack moss, while those a bit higher above frequent flood-eroding levels are green.

And another Steven Creek quiet reflecting pool with the same species. The plants framing mid-left are a mix of lighter thimbleberry and darker blackberry. To reach this area requires walking along the creek bed in shallow water.

This reflection pool just above where the creek enters Stevens Creek Reservoir was my last subject on this increasingly cloudy day with mist falling. At frame right are red ozier dogwood that are common in the area. Interestingly, few show colorful fall leaf colors like their same-species Sierra Nevada shrubs. This is within the city of Cupertino, where I went to kindergarten and first ever fished in the reservoir.
Early morning Friday, November 15, 2025, on a day with increasing light rain showers, I drove 40 miles south to Mount Madonna County Park in the Santa Cruz Mountains, which I had never visited before, in order to explore for some more bigleaf maple with fall leaves subjects.

For the first time, I hiked with my new free-standing umbrella that has a back harness. Landscapes had similar plants to those of the previous section on Stevens Creek. The above landscape along small Bodfish Creek had bigleaf maple, coast redwood, Sequoia sempervirens, California bay laurel, black cottonwood, Populus trichocarpa, sword fern, and coastal wood fern. Streambed area boulders were quite slippery when walking about.

Near the bottom of the Ridge Trail, I worked the above 30mm lens single-frame image with bigleaf maple, coast live oak, Quercus agrifolia, California bay laurel, blackberry, snowberry, and coastal wood fern. Note the raindrops' rings in the stream pool and the wet look of dry leaves.

Along the Ridge Trail where it meets Blackhawk Canyon, worked the above with a frame right, toyon, Heteromeles arbutifolia, and its red berries, plus bigleaf maple, coast redwood down in the shadows, California bay laurel, tanbark oak, coastal wood fern. The light green, wet, new grass growth has a whitish cast.

Another shrub/tree with red berries and smooth orange bark, Pacific madrone, Arbutus menziesii, plus coastal wood fern, snowberry, and greenshield lichen. Have not ID'd the two plants in the foreground, including the one with blooming white flowers, or the probable willow species in the upper left frame with much greenshield lichen. The two frame-right trees with lace lichen, Ramalina menziesii, are tanbark oaks. Oddly, poison oak was uncommon in this zone, though traveling through trailless areas would require constantly barging through dense thickets. In open areas, there were numerous fresh soil mounds from gophers.

My final subject this day, about 1pm, was the above bolete family mushroom rising up from damp, decaying leaf matter, showing its vast world of micro-organisms at work during this damp, wet season time of year. Note the resting fly with a rusty red head.
