Desert bighorn sheep – Part 1

Ancestors of the desert bighorn sheep (Ovis canadensis nelsoni) once roamed the mountains and valleys of Iran, Afghanistan, China, Mongolia, and Siberia before crossing on ice and land bridges during interglacial periods across what is now the Bering Sea into the Western Hemisphere, says Marc Jorgensen* in his comprehensive book, Desert Bighorn Sheep: Wilderness Icon.  My first close-up encounter and photo shoot with the desert bighorn sheep occurred five years ago and is documented in my posts, “Peninsular Bighorn Sheep” and “Bighorn Sheep revisited.”  My second close encounter occurred last month and is seen below and in a following post.

Coming out of the restroom in Agua Caliente Regional Park in the Anza-Borrego Desert region, I spotted desert bighorn sheep on a nearby hill just above the campsites.  Their color and size blends in well with the landscape.

This herd consisted of 14 sheep that often positioned themselves in different positions to look for danger such as mountain lions, coyotes, and humans that have been seen here.  I slowly and quietly hiked in their direction as they moved down the slope to the lush greenery around the campsites.

They first had a good look at me on the road just as they were about to cross into the campground and had to make a decision on proceeding to food or to safety.

DSC_0177_2 Decision time

I believe some recognized me from the previous encounter and others perceived I was not a threat, so they continued on toward their brunch.

DSC_0182 Crossing into campground

They enjoyed their picnic by the campsites…

until oblivious and noisy campers cut through the sites on their way to soak in the nearby spa and pools.*

So the sheep crossed back to relax in their own “day use area”…

and then settled down to relax and sunbathe.

I shared in the warmth and happiness of the moment and heard “Sunshine on my shoulders makes me happy“.*

Desert dreams of rain and flowers

I woke up from my dreams to grab my Nikon camera to catch the sun before it bore down on the Airstream Safari trailer, flowers, and bighorn sheep, as a heat wave broke over the San Diego area.

DSC_0307 Heat before sunrise

It was already warm even before the sun pierced the horizon of the Anza-Borrego Desert.

DSC_0321 Burning desert sunrise

Ocotillo leaves and flowers were shriveling up while back at camp, the trailer was making a valiant effort to keep cool by flying its sails and having all windows and vents open and numerous fans running. (See “Desert heat“)

DSC_0149 Airstream sails flying

By early morning an important decision was made to close up the Safari and turn on the air conditioning for our and our corgis’ safety and comfort.  Dogs can get hyperthermia easily as we found out when our corgi Tasha vomited several times late one afternoon, but quickly recovered the next day (See signs of heat exhaustion).

Before it got too hot, we chatted with our neighbors, Bev and George, who were thrilled to see a mother quail and four chicks again this spring (as they had in previous years).

DSC_0446 Quail and 4 chicks

George delighted in showing me the Desert Willow,* Chilopsis linearis ssp. arcuata, flowers frequented by hummingbirds.

The spring desert wildflower season is now winding down, but the Desert Agave, Agave deserti, looked triumphant with its yellow flowers on tall spikes, as I hiked the Moonlight Canyon Trail.*

DSC_0051 Desert Agave flowers

Although bighorn sheep are known to eat agave and other cacti such as hedgehog cactus, they seem to prefer to eat softer textured plants when available.  As the desert vegetation begins to dry up, the bighorn sheep have been seen coming down off the nearby protective mountains and hills in search of food near the campsites.

After their campground picnic,* they retreated to a nearby hill to rest and talk.

As I gently, quietly, and slowly approached, some of them seemed to recognize me from my first closeup encounter with them five years ago.  The 14 sheep in this herd, positioned themselves to detect danger from any direction, yet seemed perfectly relaxed during my 40-minute photo shoot.

For me, it was like a dream… and a fitting way to say “Goodbye” until we return next season when the cooler air, rains, and flowers return.  I waved to them as I left them to dream of rain and flowers in the desert sand.*

Happiness in the blooming desert

Happiness is spreading in the Anza-Borrego Desert along with the wildflowers*, so we returned to our desert home away from home and were greeted by abundant sunshine, flowers and friends, such as Ann from historic Julian, California,* who gave us a beautiful display of poet’s daffodils,* Narcissus poeticus in a mason jar before returning home.  Julian’s daffodil lady, Sally Snipes, began planting bulbs to honor her father in 1990, and now millions bloom every March.  We’ll return here with our Airstream Safari in May.

We arrived in Agua Caliente County Park* on the first day of spring, the spring equinox,* and enjoyed the longer daylight to set up camp, while bathed with warm, early evening breezes and a waxing moon.  Three evenings later, the Full Worm Moon* rose, along with a penumbral eclipse.*

DSC_0198 Full Worm Moon 2016

A happy sun looked down upon hamantaschen* that I made and brought from home to celebrate Purim.*

DSC_0016 Hamantaschen for Purim

Like all days of celebration, Purim is a wonderful time to get together with friends, so we visited Bert and Janie (and their Classic Airstream trailer) in Borrego Springs and shared cha siu bao* and hamantaschen.

DSC_0192 Bert, Janie, Larry & Bill

Most of our time in the desert was spent exploring and admiring the Anza-Borrego spring flowers.  Larry found a coyote gourd.*

DSC_0021 Larry & coyote gourd

A nearby palo verde tree, Parkinsonia florida, was exploding with yellow flowers that peaked during our stay!

DSC_0131 Flowering palo verde

Also nearby, was a wash where Larry was thrilled to find a large mound of Krameria bicolor, aka Krameria grayi, in full bloom.  The close-up shows the flowers and its barbed fruit.

Nearby this Krameria were two clumps of strawberry hedgehog cactus, Echinocereus engelmannii, with profuse blooms that closed at night and opened during the day. (See Bert Gildart’s “Botanical Adaptions to the Desert“.)

Also making the point in the area is Gander’s Cholla, Cilindropuntia ganderi.

And when the sun set, the moon bloomed and the stars danced with happiness!*

Monkey business under the Hunger Moon

The Hunger Moon* was rising as we unhitched our Airstream Safari in the California desert, which marked the conclusion of the 15-day celebration of the Chinese New Year, the Year of the Monkey.*

DSC_0038 Hunger Moon 2016

This moon is also called the Snow Moon* because it usually occurs during the snowiest month of the year, but in San Diego, we just had the hottest February since records began in 1874.  Here in the desert, we experienced comfortably warm, sunny days, and cool, clear nights that were perfect for celebrating the Chinese Lantern Festival* as we did last year at this site, except this time, we suspended a large paper Chinese lantern with string attached to a long bamboo stick from our garden.

DSC_0049 Chinese Lantern Festival Full Moon

Evening breezes made low light photography of this large paper Chinese lantern challenging until I held on to it…

while our Chinese lucky lion* looked on and laughed (perhaps regarding the Year of the Monkey political predictions)!

DSC_0065 Chinese lantern festival lion

The Chinese New Year* is also known as the Spring Festival,* and this year, it felt like spring arrived early at our campsite, especially with freshly cut Freesia flowers that Larry brought from home.

DSC_0007 Spring Year of the Monkey

Larry also brought a pork and mushroom mixture that was placed in dumpling wrappers to make siu mai,* which were then steamed.

Recent rain and warmer temperatures have brought new growth and flowers to Agua Caliente’s Moonlight Canyon flora.

DSC_0097 Moonlight Canyon

Swaths of red were seen across the desert due to prolific chuparosa, Justicia californica, blooms.

DSC_0106 Agua Caliente chuparosa

And a beautiful and fragrant Cattleya bloom greeted us upon arrival home and seemed to announce the arrival of spring!

“Winter is gone, the mountains are clear, and water sparkles… Spring comes, birds sing, and flowers fragrant.” (A Chinese Spring Festival – New Year’s couplet,* Chun lian.)

Tire pressure monitoring system II

Special Trailer (ST) tires have a maximum speed rating of 65 mph,* and if exceeded or if the tires are under-inflated, the tire temperatures increase, causing a weakening of the tire structure, which can lead to a shortening of the life expectancy of the tire and/or a catastrophic accident.* We have learned the importance of continuously monitoring the tire pressures (and our speed) from preflight to our arrival and midway during our stay and during our return trip home.    To facilitate this, we have relied on a tire pressure monitoring system (TPMS) since 2008, first with Doran, and then with PressurePro since 2011 (See “TPMS-Update“)

DSC_0005 PressurePro monitor

Typically, two or three days before departure, I install the sensors on the tires and adjust the tire pressure to be as close as possible to the specified maximum 50 PSI cold for our ST 215/75R14 Goodyear Marathon tires for the expected temperature at the time of departure.  (Our tow vehicle’s truck tires also get the sensors and have a cold PSI of 60 for front and 75 for rear tires.)

DSC_0200 ST Tire, PSI spec- cold 50

I keep a running log of the pressures and temperatures for each trip, which is started at the beginning of our trailer trip prep week and detailed in my post “Airstream Safari trip notes.”

DSC_0123 Tire pressure logOn the left is the log for our December trip.  The sensors were installed on Thursday and I noticed that the street-side rear sensor pressure reading was lower than the other sensors, which may indicate a slow tire or sensor leak.  I added air to this tire on the following day.  Early Saturday morning, the outside air temperature was 40°, and I noticed that the rear curbside sensor was not transmitting a pressure reading until it warmed up to 50°.  We departed Sunday afternoon and when we arrived at our campsite, I discovered a 1″ washer head machine screw embedded in our rear curbside tire as I was covering it for the night.  The next day, our PressurePro monitor confirmed my fear that the screw had penetrated the inner tire.  I replaced this tire with the spare and documented this in my post, “A Marathon tire repair.”

DSC_0015 I" machine screw in tireWasher head machine screws, commonly used on automobiles and motorcycles, are often encountered on highways and back roads, and I suspect that the washer head, when run over, causes the opposite end to rise towards the tire and puncture it straight on.

We find the most screws and nails in campgrounds, often brought in with firewood by campers, as seen in my post, “Nailing it… A TPMS encore.”

This camping season, our PressurePro TPMS sensors became 5 years old and were showing their age.  As seen in the log above, one was not transmitting a pressure reading in the early morning cold and another was very slowly leaking air, confirmed by temporarily putting another sensor in its place.  I contacted PressurePro and they sent me 4 new sensors for my trailer at a discounted rate, along with a Sensor Seal/Installation Tool Kit, that I will use to upgrade the truck’s sensors.

DSC_0012 New PressurePro sensor

An obvious improvement in the new sensors is that each sensor has a unique green identification number displayed on its side, which decreases the chances of placing a sensor on the wrong location.  (Each sensor is programmed for each tire location and I place each sensor in a zip lock bag assigned for each tire location when not in use, thus prolonging the battery life.  See how to set up the PressurePro tire pressure monitoring system in the video, “Protect Your RV with a TPMS“*)

A less obvious, but more important improvement is that the new PressurePro sensors now have a new Sensor Seal, a two-piece valve system that uses a hard plastic depressor to more fully depress the valve and yet, provides a hard stop during installation, protecting the seal. (Older sensors were often over tightened, resulting in damage to the O-ring seal.)  Older sensors with the one-piece seal can be upgraded by using PressurePro’s Sensor Seal/Installation Tool Kit that contains 10 sensor seals and a seal installation tool.

A tire pressure monitoring system adds to our peace of mind while on our safaris, where we’d rather come face to face with a coyote than with tire trouble!  (See Author’s update below regarding high temperature alerts and other PressurePro improvements.)
