The Black Tailed Jackrabbit (Lepus californicus) commonly known as the American Desert Hare makes its home in the western half of the United States including California, Nevada, Arizona and parts of Mexico. One of the largest species of hare, the animal boasts large distinctive ears, powerful rear legs, black tips on its ears and a black tail for which the animal gets its name.

This species of hare commonly reaches sizes of 18 to 24 inches long and may weigh between 4 and 8 pounds. Typically, the females are slightly larger compared to the males. The animal will mate ear round depending upon environment and the young are born with a full compliment of fir and open eyes, which classifies it as a true hare and not a rabbit, despite its common name. The female does not build elaborate nests for birth. A new born hare is and well camouflaged and quite mobile within minutes of birth. The juveniles will stay near the mother for nursing, but are not protected by the mother.

Commonly found in desert scrub, prairies and meadows at elevations up to 10,000 feet, the Black Tailed Jackrabbit is quite adaptive to various environments. Camouflage is their only defense, and they will freeze when a threat is near. Their diet consists of a variety of green vegetation and grasses, however they are known to consume dried or woody plants in the harsh winter months. The hare does not hibernate during the winter months.

The Black Tailed Jackrabbit is a valuable member of the ecosystem. It serves as a prey item of other carnivorous animals including coyotes, foxes, eagles, hawks, owls and various Native American tribes.

Desert Horned Lizard (Phrynosoma platyrhinos), also known as the “horny toad”, is a common North American reptile and found throughout the southwest and the Mojave. A personal childhood favorite of mine, the horned lizard does have the appearance of a small dinosaur and it a master of camouflage.

This is a small to medium sized lizard, its 3 – 5 inch broad and flat body features a prominent series of fringed scales. Its head also boasts several horn which offers the lizard its name. Undoubtedly, the overall body shape is that of a toad is also a contributing factor. The coloration of the body will vary to help the lizard blend into its background.

The reptile’s diet is small insects and is commonly found at or near ant mounds where they will lie in wait for its meal to simply walk by. Generally speaking this animal is found at elevations below 6500 feet in creosote-bursage flats and Mojave Desert Scrub.

Defensively, the little lizard is all about appearances. Primarily, camoflauge allows it to remain hidden in plain sight. The reptile is known to hiss and puff up its chest when confronted in an effort to appear larger and more dangerous that it really is known to be. Some species of the genus are known to squirt blood from its eyes and may reach a distance of 5 feet.

Mustang (Equus ferus caballus)

Left behind by Spanish explorers and settlers, the Mustang ( Equus ferus caballus ) of the desert south west is alive and well in Nevada and a symbol of the southwest. Due to the fact that this animal population is descendant from a domesticated population the Mustang is actually a feral horse. The imagery of a wild mustang galloping across the desert as burnt into the memories of kids who watched “Western” movies or appreciate classic cars. The wild mustang brings one to think of power and freedom.

There is much debate when it comes to the wild Mustangs of Nevada. Some will debate weather you consider them an invasive species and a natural species. However, you consider them, they are thriving and a part of the landscape at this point. Should you happen upon them, you can not help but feel lucky.

The wild horse populations are separated by long distances, so each isolated herd has developed specific genetic traits. Some consider the horse populations a nuisance which destroy the terrain with their appetite. Their hooves can be quite destructive to the landscape and ranch land. Although considered “culturally significant”, the horse populations are closely monitored by the Bureau of Land Management to ensure healthy herd populations.

Population increases of about 20% per year have prompted the BLM to capture some of the horses. The captured horses are not euthanized, and instead are available for adoption for the cost of $125. Horses which are not adopted are held in “long term holding”, which costs the US Tax Payer about $50,000 over the lifetime of each individual horse.

On a trip to see the mustangs near Cold Creek, Nevada, we ran across the local herd lazily walking along the side of the road. We slowed the jeep down, and which point the horses started to walk up to the car looking for some food (which we did not provide). Not exactly the in line with the western movies of my youth.

Speckled Rattlesnake ( Crotalus mitchellii )

The Speckled Rattlesnake is fairly common pit viper found in southern California, southern Nevada, western Arizona and south-western Utah and down the Pacific coast into Baja California.  A moderate size snake, this animal typically does not exceed 39 inches in length.  As with most animals, the Speckled Rattlesnake is a master of disguise and commonly are colored to compliment the surrounding rock.  This viper can range from pink, cream, tan or pale blues and grays.  This feature I can personally attest to as I witnessed and entire Cub Scout Pack literally step over the specimen photographed below while hiking on a camping trip in the Valley of Fire State Park just outside of Las Vegas, Nevada.

Mojave Goldfish

Over Presidents day weekend, my wife and I were travelling back from Big Bear, CA to our house after a visit with family towards our home in Las Vegas.  Frequently, my wife will point out an old road or mine and comment that we need to take that trail someday.  During out drive home, we were talking about the mining district in Mountain Pass and the Evening Star mine.  On this journey, we chanced upon the ultra rare Mojave Goldfish.

This is one of the great reasons for owning a 4×4 and the Mojave Desert is a prime location to explore.

So, we exited the I-15 travelling north on Baily road near the Kokoweef mine.  Typically, I have a route mapped out ahead of time, but a spur of the moment decision left our route to happenstance.   We drove straight off the off ramp and headed up the hill.  Immediately I sensed the I took the wrong route, but since we were exploring I just drove on, you never know what you will find.  Soon, we found a private property sign, and opt towards a road to the left.  I found 4×4 low in the transfer case and we climbed a short hill.  Upon cresting the hill, I noticed something metal down the the left.  I road the gears down in low until we reached the small canyon where I made a tight left towards the metallic object I saw from the top of the hill.

Within a quarter of a mile, I found an juniper tree with a metal water trough.  These are not uncommon in the mojave and can be found throughout the dessert.  I parked the jeep to investigate and was shocked…

We stumbled upon Goldfish, in the Mojave Desert and these things were pretty big.  I mean, I have eaten trout smaller than some of these.  Goldfish are used to keep the algae in check inside the water trough.  An elegant solution to a problem I didn’t think existed, but that makes sense.  The water trough was plumbed with a PVC pipe to bring the spring water to the trough.  The overflow, did just that and the rocks on either wide of the trough edge allow for animals to escape the tank.  An endless supply of fresh water would keep the urea concentrations down, so the fish grow into their environment.

My biggest question is that in a remote area with a lot of preditors, why are these fish alive?  I thought that an oportunistic coyote, fox or raven would make quick work of this exposed tank, but these large fish prove they have been here for time.  Regardless a very fun find and a true 4×4 destination.
