Redwood Sorrel in bloom in in the Sinkyone Wilderness



During a trip to the Redwood Coast of California in August, 2014, the Redwood Sorrel flowers were in bloom. You sometimes see another type of sorrel growing in people's yards which you can recognize by the leaves, but this one is a wild species native to California. It grows in shady places under the big trees and up the coast into Washington state. This flower has 5 petals with purple veins and 10 stamens. Plants in the sorrel family, including Oxalis, have sour sap.

This Redwood Sorrel was blooming in the Sinkyone Wilderness State Park. We saw it during an overnight backpack trip where we camped near a beach. This part of California's coastline is the most remote coast in the state, even though the area used to have a large lumber operation that ceased operating many decades ago.

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.

Coyote near Sentinel Dome in Yosemite National Park in winter




On one of our many cross country ski trips along the Glacier Point Road in Yosemite National Park, we camped near Sentinel Dome late at night and didn't awaken until late the next morning.  As we were lying in our tent, we heard an animal trotting through the snow around us.  We looked outside and saw this coyote approach us as though he was expecting us to give him a handout.  Eventually he moved in closer and laid down in the snow and waited to see what we would do.  He was only about ten feet away.  While he waited, a second coyote bounded in and the two of them chased each other around until they both ran off.

 Actually we were a little concerned that the coyote might run off with a piece of our gear.  The night before as we were skiing in we encountered a couple of skiers heading out at about 3 A.M.  They told us that they had encountered a coyote a couple of hours earlier when they had stopped for a rest break.  The coyote was trying to get some food from them and they responded by throwing snowballs at him to shoo him away.  Eventually the coyote gave up, but not before grabbing one of their ski poles and running off with it.  The two skiers who told us this story asked us to keep an eye out for their friend who was trailing behind them.  As we continued skiing in, we encountered the other skier, who was using a roadside marker as a not-very-effective replacement ski pole, about twenty minutes later.  We let him know how far behind his friends he was and he thanked us and then said that he would do that coyote in, if he ever caught him.

Salt Creek pupfish, an endangered species in Death Valley National Park, Spring 2012




During the spring, the endangered Salt Creek pupfish males set up territories in Salt Creek as if flows from a spring south to the below sea level section of Death Valley National Park. The pupfish are considered the remnants of fish that once inhabited Lake Manly which filled what is now Death Valley during the last ice age. As the water level receded as the ice age ended, the water became saltier and now only a few springs persist and provide the only habitat for this species. Besides the saltiness, this creek experiences flash floods, nearly drying out, and temperatures from near freezing to over 40°C. (104°F.)

This image was taken by hiking along the boardwalk of the Salt Creek Interpretive Trail, a short turnoff from Highway 190, between Stovepipe Wells and Furnace Creek, the two main developed areas within Death Valley. Rick got down on his belly and waited for a male to swim near the shore to get this shot. You can tell it's a male because of how colorful the front is and by the bluish dorsal fin. Females are better camoflouged and blend in with the grainy creek bottom.

Bull elk in velvet along the trail in the Sinkyone Wilderness State Park, California. 2014-08-08



We encountered this bull elk along the trail in the Sinkyone Wilderness State Park, California, while heading back to the trailhead during a backpacking trip. In early August, the elk's antlers would still be growing with the furry-skinned velvet covering them as they're growing. Later, when the antlers are finished growing, the velvet will die and slough off. Sometimes, the elk will get an itchy feeling from the whithering velvet and feel the need to rub the antlers against a tree or shrub to get the velvet to come off faster.

This particular elk didn't seem to have any problem with our presence and was actually lying down when we first came across him. Another bull elk headed downslope off the trail at a leisurely pace and got his antlers caught in grape vines.

Skiing near Mount Lassen, Lassen Volcanic National Park, CA


Richard Robinson poses in front of Mount Lassen in Lassen Volcanic National Park at the end of a two-night ski-packing trip.  The Lassen National Park Highway is closed through the park during the winter making it available for cross country skiers and snowshoers.

Sagebrush Mariposa Lily with a small insect inside from Lava Beds National Monument, CA


This is a Sagebrush Mariposa Lily (Calochortus macrocarpus) with a small insect inside.  It was blooming in Lava Beds National Monument in northeastern California.  This park is famous for its numerous lava flows that have produced hundreds of lava caves, some of which are easy to explore.

Honey Bee in Blackberry flowers along the California north coast




During a trip to the north coast of California to see the Redwoods National Park, Rick and his wife spent some time enjoying the blackberries. For a couple of hours, they turned into grazers and kept finding one good patch after another. The blackberry bushes had ripe fruit, but were also flowering. This honey bee was busily flitting from one flower to another. Rick had to use a fast shutter speed and multiple shots to get one where the bee had settled onto a flower and the wings were still. The honey bee isn't native to North America, but was brought from Europe and has spread across the entire continent. But something is threatening these highly important pollinators with a condition called Colony Collapse Disorder. Losing the pollination services of bees would be a huge disaster for us humans.

Cape Mendocino and the Sugarloaf Island on an overcast day




Cape Mendocino with the Sugarloaf Island just off the coast of California during an overcast day.This is perhaps California's most remote coastal area to which you can drive. The drive here involves winding 2-lane roads that often look in dire need of maintenance. The area is also mainly private land, so there are only a few places where you can stop and take in the scenery. The Sugarloaf Island really stood out because of how white it appears, even on this overcast day it appeared bright.

This image is the result of two images merged together to create a wider final product. I made sure not to include the breaking waves in the right image, so that only the left image had the waves, so that merging the two images wouldn't end up with blurred waves in the final image.

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.

Sequoia-Kings Canyon's Crystal Cave showing cave drapery




This image was taken while on a tour of Crystal Cave in Sequoia National Park. Caves of this type form underground by water that has become weakly acidic by absorbing carbon dioxide, then dissolving away limestone or marble to create a cavity in the earth. The original rocks of the cave wall are collectively called speleogen. This type of cave is called a solution cave, due to the way it forms. After forming, the water continues dissolving minerals underground and dripping down through the cave. When the drops dry up, the calcium carbonate mineral is left behind, forming the cave features most people associate with caves. These formations are normally white, but may be tinged with orange or reddish streaks if the minerals have iron mixed in. These features that form after the cave walls, speleogen, are called speleothems. These particular kinds of speleothems are called cave draperies.

Photographically, the white calcium carbonate makes for a challenge since it can end up washed out by the flash. Having the light bright, but diffused, helps create an even lighting across the surface of the features instead of having a bright spot where the light from the flash ends up being too concentrated. A simple technique for achieving this effect is to move farther away from the features and use the telephoto zoom lens in combination with the flash, which is how this image was made. Not only will the light be softer, but cave drapery and other bright cave features to the side will reflect the light soften the shadows.

Yosemite's Half Dome with a nearly full moon rising during the winter





During a winter cross-country skiing trip, we were out during the time that the full moon wold be coming up alittle before the sun would set completely. That's what made this shot possible. To have the foreground lit up with the moon in the distance, you have to be out one or two days before the full moon. The Glacier Point Road is closed to cars during the winter, so one has to ski, snowshoe, or snow boot travel from Badger Pass to Glacier Point, a distance of about 10 and a half miles, one way. We camped out in the snow for one night, before heading back to Badger Pass.

In this image, you can see Half Dome, the Clark Range to the right, with Tenaya Canyon and North Dome to the left. The image is the result of merging 4 separate images together to get more detail.

Yosemite's "Gateway" from the west to east from Tunnel View area



Yosemite Valley's "Gateway" is the Cathedral Rocks to the south and El Capitan to the north. This view was taken from the Tunnel View looking eastward from above the valley floor. Below the Cathedral Rocks is Bridalveil Falls. Beyond them is Sentinel Dome, in this photo it is covered in snow and showing above the lowest of the Cathedral Rocks. Beyond Sentinel Dome, is Half Dome, Yosemite's most famous land mark. Then, beyond Half Dome, in the center of the photo, is Clouds Rest. It's covered in snow and has a long north-facing slope. Clouds Rest is actually 1000 feet higher in elevation than Half Dome.

We drove to Yosemite from Fresno, California and parked at the popular Tunnel View turnout. However, Rick knows some locations around there that the typical tourist doesn't go to, allowing for a view that's not so common. This image is the combination of 4 images combined in the computer to get much more resolution, as well. The day was sunny despite being in February.
