A FOREST IN THE DESERT





Joshua Trees




So named as early Mormon emigrants saw, in the shape of some of these large yuccas, Joshua with his arms thrown to the heavens. Ranchers and miners used the sharp pointed leaves as fencing and the trunks for burnable fuel for early ore smelters. Even earlier inhabitants, Indians, used the leaves to make woven baskets and sandals. The seeds are edible.



Though not what you and I might typically call a forest, they do grow in groves. Healthy trees can often last 100 years and some have been found that are 1,000 years old. Root systems can spread 30 to 40 feet outward. Though there were no big yuccas visible here, they can grow to almost 50' tall.

FLATTER THAN FLAT





Racetrack Playa









Tiny as ants, these visitors are out on Racetrack Playa. Though "playa" is Spanish for beach, in geology it means the flattest possible natural surface. This is also a near-permanently dry lake.


What the surface of Racetrack looks like up close.




In the middle of this 2.5 mile long oval is this excretion of rock called, what else but, "The Grandstand." The day I visited I was surprised to find rock climbers tethered to a boulder or two. 



There is only a 1.5 inch differential over the playa's entire 3 square mile surface. You may have read about "mystery rocks" that move and leave tracks across the playa without human intervention. Best educated guess comes from NASA. Winds are very strong in this narrow valley. When an infrequent rain hits the playa, it turns the hard pan into shallow silt. Stiff winds follow and can move the stones across the surface and cause the weight of the rock to carve its path on the playa.

SO THAT'S WHERE THE NAME CAME FROM





Teakettle Junction




This colorful bit of remote humor is in nice relief from the starkness that is Death Valley. 
Teakettle Junction is on the way to the Racetrack - which is the next stop on the blog too.

UBEHEBE CRATER





Death Valley's Volcanic Past



No matter where you stand it is difficult to convey the size of the bowl that is Ubehebe Crater. 
This volcanic eruption is relatively new - just 2,000 years old!



The crater does show its age in a different way. 
Pronounced as it looks, U be he be, each layer of rock represents several millions of years in the building of the earth's crust.




This Google Earth screen capture conveys a little bit better the size. 
It is one-half mile wide and over 700 feet deep. Other volcanic eruptions are visible as well.

MOSAIC CANYON





Marbleous!



Like a multilayered wedding cake, Mosaic Canyon is a confection but one made of stone.



In places the rock looks rough and brittle. Adjacent deposits though are hard and as beautiful as some of finest Roman marble. 900 million years ago magnesium rich limestone deposits (called "Noonday Dolomite") were laid down then buried deep. The depth also produced great pressures and temperatures that caused the limestone to metamorphose into marble. Tectonic forces pushed this remade material to the surface and you can see this unique layer in the canyon.


It doesn't take long to hike up Mosaic Canyon to see its wonders. 
The trip back down features a different beauty as the distant desert floor commands your view.


Inhospitable as this dry canyon first appears, there are pockets of hardy greenery. Spiny and waxy, this Rock Nettle somehow thrives and survives. Despite its thorny appearance, blossoms are pleasingly fragrant.

SCOTTY'S OTHER "CASTLE"





Where Legends Really Reside



A man's home is his castle, or so it is said. Not for Walter Scott, the "Scotty" in Scotty's Castle. When the gates were closed, Scotty didn't bunk down here if he could avoid it. For many years Scotty was whomever other people wanted him to be: a cowboy in Buffalo Bill's Wild West Show; a huckster, verging on the criminal, for low-grade mines and finally, entertainer for eccentric Albert Johnson's guests. It was Johnson's vision and money that built Scotty's Castle. The real Scotty was an ornament.



In some respects Albert Johnson was an honorable man and more than likely became one of Scotty's few real friends. Johnson built not only the Castle but also the house that Scotty got to live in and finally be himself.



Unusually plush for a simple desert structure, considering it was built in the late 1920s. It was constructed with 2x6 insulated walls and clad inside and out in redwood. Scotty's real home was truly his castle.



Here he could be himself. And that self was a slob, as this one of many historic photos indicates. The National Park Service has obviously cleaned things up. The tour is not often offered. Indeed there were only 3 of us that met the ranger for the mile hike to Scotty's home.



Both the Castle and the cabin share the same method of fencing that has been in place for almost 100 years. The wire fence has never had to be replaced as rust is held in check by the remarkably low humidity and lack of rain. The fence also surrounds both properties. The "S" & "J" stand for Scott and Johnson. From the hills behind that fence springs give up 420 gallons per minute. That's what the fence protected.



With the same fencing as mute evidence in the background, our guide, Ranger Scott Combs, shows how Albert Johnson defused the barricading of the water supply for those who once lived or ran animals in the area. He built the stone structure visible in both the photo and behind our guide. It was a catchbasin for a water pipe that delivered water to those outside the fence. That is Walter Scott and Albert Johnson by the cistern.

At one time, Johnson and Scott cleared a 5 acre plot and for one season planted and harvested alfalfa in order to meet government requirements for homesteading the land.


Characters and charlatans come and go, but what is almost ever present is the animal life that surrounds us, all the more remarkable in Death Valley. The National Park Service chooses not to use traditional bait (which may kill other critters) but rather the lure of a nesting material (cotton). Our guide told us that in three years giving this tour in the Park, he's never seen a trap sprung.

FENCE GALLS





AKA: Cyclone Galls




This is only the second time I've seen this phenomena of galls growing on fencing. Biologists say it is a little understood feature of nature. They are thought to be caused by insects interacting with the metal in the fence. In some cultures, the galls are a food source. Often the galls are used as a host to larva. Due to the time of the year these are seen, the insects that caused this anomaly are called April Foolish Buggers. Keep smiling and pass it along.
