Great Basin national park in east-central Nevada near the Utah border is a relatively new member (established in 1986) of the national park system. Named for its unique hydrology as a collection bowl that only drains internally: i.e., water flows into the Great Basin, pools briefly, then drains through the crust or evaporates, with no flow leaving the basin.
But, Lehman cave was what we came to this park to see. The cave was discovered in the 1880s, was privately owned for a while, made into a national monument in 1922, and then incorporated into the much larger national park. Some of the most unique of all cave formations are found in abundance here —
“Lehman Caves has such familiar cave formations as stalactites, stalagmites, columns, draperies, flowstone and soda straws. There are also some rarities such as shields, which consist of two roughly circular plates fastened together like fattened clam shells, often with graceful stalactites and draperies hanging from their lower plate. Lehman Caves is most famous for its abundance of shields.A shield called the Parachute and other formations make touring Lehman Caves an unusual and rewarding experience. Delicate helictites, small branching formations that defy gravity, and anthodites, small needle-like crystals of aragonite, are also found throughout the caves. Cave popcorn resembling the edible variety, adorns many walls.” (https://www.desertusa.com/grb/lehman.html)
No flash photography is allowed in the cave, but the formations are well lit so that a camera phone can capture their beauty. Passageways are very narrow, with delicate formations right in the middle of the path that we had to carefully walk around without touching. The formations are wet, and water drips continuously from the ceiling, so the path is slippery in some places. Needless to say, our visit here was one of the highlights of the “road trip-2022”.
The two youngest grandsons accompanied us from California back to Minnesota at the conclusion of the annual Sierra backpacking trip. Of course, it’s standard practice to stop at various geographic and geological wonders along the way to educate and entertain the youngsters (both teen-agers now). This sometimes results in ”misadventures” instead of just adventures, but there were no flat tires on this trip, unlike the previous summer’s trifecta of blown rubber.
Once again over the crest of the Sierras, we traveled on Hwy 50 (“the loneliest road in America”) across Nevada. Although most people avoid driving this road because of its supposedly monotonous features, we always find plenty to look at.
The park is located near the once-booming, mining town of Berlin, 20 miles east of Gabbs, NV, in the foothills of the Shoshone Mountains. More than a ton of gold was mined here,- valued at $850,000 in 1890 prices ($20/ounce). The thriving town of about 300 miners, merchants, etc. was deserted when the ore vein ran out, but it never burned, so many of the original buildings and some of the equipment used still remain.
I should have posted this composite image of White-winged Doves coming to and leaving a perch yesterday — when it was National Pigeon/Dove day. Oh well….hence, the title of the post.
These doves are native to central America and Mexico, but expand northward into southern most CA, AZ, NM, and TX during their breeding season. They time their arrival with the blooming and fruiting of the saguaro cactus, feasting on its nectar, pollen, flowers, and seeds. In fact, the tiny seeds of the saguaro are the only ones the doves will consume, because they are so easy to pick out of the cup-shaped fruit.
Many dove species are particularly successful in hot, dry desert environments — they are the only birds that can pump or suck up water with their bills immersed so they can rehydrate quickly, and they are strong flyers that can search for waterholes within a wide radius of their nest. Once well hydrated doves can evaporatively cool themselves by panting, even at air temperatures in excess of 120 degrees F (50 degrees C). Amazing survivors!
Our morning photography sessions in the Alan Murphy Arizona photography workshop began at 4:30 a.m. with a drive into a canyon in the foothills southeast of Green Valley, AZ. A short hike down a steep hill brought us to an almost flat spot where we set up our cameras in a tent blind while workshop leader Alan Murphy and assistant Dano Grayson “decorated” the site with branches, flowers, and perches and loaded them with bird treats.
As any fan of morning cartoons from the 1950s knows, Roadrunners are very fast runners (more than twice as a fast as the average human), and they use that leg speed to run down and capture slower moving prey. We had a demonstration of that late one afternoon in our Alan Murphy photography workshop near Green Valley, AZ.
Lizards don’t usually perch this high on a dead cholla trunk, but they do climb into the middle of bushes or align themselves vertically on a bare stem in the middle of the day to avoid the direct solar radiation. However, in this case, the lizard is more or less a “sitting duck” on this high perch.
Down on the ground, the Roadrunner definitely has an advantage. They can sprint at top speeds of 26 mph, but are also capable of chasing over long distances at just under 20 mph (note: the average “fit” human can run a mile at 6-8 mph).
Roadrunners are opportunistic in their hunting; they can capture (and eat) a wide variety of animals such as grasshoppers and tarantula hawk wasps, tarantulas, scorpions, lizards (even venomous ones), snakes (even small rattlesnakes), small birds and nestlings, small mammals, some fruits and seeds from cactus and sumac. It is one of the few predators that can consume venomous prey!
While watching hummingbirds at a feeder last year in Portal, AZ, we saw a Roadrunner dash up to the feeder, leap into the air, and snatch a hummingbird while it was hovering. Needless to say, Roadrunners are amazingly quick!
We set up for our late afternoon photography sessions with Alan Murphy at a private home site about 13 miles south of Green Valley AZ, where a man-made pond drew in the wildlife as the heat of the day finally waned.
Water is not required for the survival of some desert animals: many lizard and bird species can save water by making a concentrated urinary-fecal paste instead of losing water as urine; and some desert mammals can make a highly concentrated urine that minimizes their water loss from that avenue. But most animal species will utilize fresh water for bathing and drinking if they have access to it.
After sunset, we set up our cameras to capture photos of bats flying across the pond by focusing on a particular spot, and then shooting continuous 20-sec exposures for the duration of the night (that’s 3 shots per minute, 60 minutes per hour, for about 12 hours = about 2000 shots). Bats flying across the pond would trigger a strobe light that provided the illumination for the images, and on the first night we tried this, I managed to get 63 images with bats, or parts of bats, in them. Not bad for a first try.
We had numerous opportunities to photograph birds in flight at Alan Murphy’s Bird photography workshop outside of Green Valley, Arizona this past week. There were so many good opportunities that I wanted to capture their flight in just one composited image. In case you’re not familiar with this technique, I overlaid successive images taken of their flight onto the image of the right-most bird in the photo — in this case using the double exposure tool in SnapSeed.
Alan has perfected the set-up for capturing birds in flight by placing entry points to feeding sites, so that birds fly directly across in front of us from one perch to another on the same focal plane. With cameras set at 1/1000-1/2000 second with a capture rate of 20-24 frames per second, we can capture 6-10 decent images of flight.
And just for fun, I tried my luck capturing the take-off of the golden paper wasp from the small pond in front of our blind…and luck it really was because I only managed to do it once.
We sit quietly in chairs placed strategically near bird feeders, waiting expectantly with cameras on laps and binoculars glued to eyes, searching for that iconic shot of some new bird we’ve never seen before, or a better shot of a bird we have seen many times before. When we’ve exhausted the possibilities at one site, we get in the car and move on to the next one. It’s such hard work…(not). But it’s the thrill of the hunt for the best shot that keeps us going from place to place.
In Portal, Arizona, in the foothills of the Chiricahua mountains, you are welcome to visit the backyards of the local residents to sit and photograph the birds that visit their feeders. At this particular backyard, a Roadrunner (lower left of the photo) walked through the backyard looking for an unwary bird to capture. It made a half-hearted attempt to lunge at a hummer on one of the feeders in the photo above, but gave up and moved on. We heard it had grabbed and eaten a Cactus Wren just a half hour before.
What can you see in just a couple hours time in the Sonoran desert north of Tucson? Quite a lot it turns out! We bagged (photo-wise) a badger and a roadrunner in the first 15 minutes after getting out of the car at Catalina State Park, and thought we were off to a good start finding animals we hadn’t yet seen on the trip.
Crossing the dry wash and climbing the adjacent hill we found a few old friends:
