Three Kids Manganese Mine

Manganese mine -  In the late 18th and early 19th centuries, manganese, an important metal needed to strengthen steel, was supplied to Untied States manufacturers mostly by foreign mines.  With the onset of World War I, these sources of manganese were cut-off, and an intense search for domestic sources was undertaken.  In Nevada, this prospecting effort led to the discovery of the Three Kids manganese deposit in 1917.  This mine provided most of Nevada’s manganese production during the last two years of WWI and operated intermittently until 1961.  This is the largest manganese mine in Nevada and, during the 44 years of operation, more than 2,225,000 tons of ore ranging from 15 percent to 40 percent manganese was mined and treated here.  Small amounts of lead, copper, silver and gold were also recovered by the mining operation.

The Three Kids Mine is on private land and access is strictly controlled. This and any other abandoned mines you might come across can be extremely dangerous. Resist any temptation you may have to explore these workings – ” Stay Out and stay alive!”

Coyotes part of living in Southern Nevada by NDOW

January 19, 2010 – Here is the poop on Coyotes in Southern Nevada straight from the horses mouth, Nevada Department of Wildlife. This as you will see appeared in the Las Vegas Review Journal January 17th, 2010 under Outdoor Briefs.. It makes good reading and covers many of the items found on coyotes elsewhere in this BLOG.

Coyotes part of living in Southern Nevada

Like many communities across the Southwest, those in the Las Vegas Valley have seen residential and commercial development reach into areas that were previously undeveloped. As it has elsewhere, that development has had a direct impact on numerous wildlife species and their habitats. While some species suffer from the impacts of urban development, the wily coyote continues to thrive.

From their original haunts, which extended from parts of north-central Mexico to southwestern Canada, coyotes have extended their range to nearly all of North America. Their range includes urban centers such as Los Angeles, Phoenix and Las Vegas.

“The amazing thing about coyotes is their ability to adapt and adjust to changes in their natural environment and to the challenges of living in an urban environment. They can sometimes be seen roaming areas located on the outskirts of the Las Vegas Valley and even farther into town,” said Doug Nielsen, conservation education supervisor for the Nevada Department of Wildlife.

A popular drawing card for Southern Nevada homebuyers are golf courses, water-based landscape design and life on the edge of natural surroundings. What homebuyers often fail to realize is that these qualities are just as attractive to a variety of wildlife, coyotes and other predators that are already living in the Mojave Desert.

“Oftentimes people buy homes on the desert’s edge so they can have a more natural experience, but they want to pick and choose what critters come to visit. It just doesn’t work that way,” Nielsen said. “Golf courses, landscaping with water features, and washes or other avenues that provide animals with direct access to and from open desert areas will sooner or later attract prey species such as squirrels, rabbits and birds. These species then become an attractant for coyotes and other predators looking for a meal.”

Though coyotes have been known to hunt and eat domestic pets, simply seeing one is not necessarily cause for alarm. Nor is it necessary to call NDOW. However, a call may be warranted anytime a coyote is showing threatening behavior toward people, especially children. The key to preventing possible conflicts with coyotes or other wildlife, according to NDOW, is to eliminate those things that attract them, beginning with possible food sources.

Never feed coyotes and encourage your neighbors not to feed them. Wild animals quickly become habituated to humans as a food source. Store pet food inside and feed pets inside if possible. If a pet must be fed outside, clean up any uneaten food.

Pets, especially small ones, should not be left outside unattended. This is especially true at dawn or dusk when coyotes are most active. If it is necessary to leave a small pet outside unattended, consider keeping it in a sturdy enclosure with a roof. It’s also a good idea to trim or remove any ground-level shrubs and branches that could provide coyotes with a hiding place.

Coyote attacks on humans are a rare occurrence, and when it does happen, the attacks are generally directed at young children.

Should you encounter a coyote, make loud noises, wave your hands or objects such as a stick or broom, or spray the coyote with water from a garden hose. Don’t turn away or run, because that may trigger the animal’s predator extinct, but don’t corner a coyote either. Give the animal room to escape.

More information about living with coyotes can be found online at www.ndow.org.

McKeeversville, earliest settlement in the Boulder City area

Historic site…McKeeversville pre-dates Boulder City. It was where some of the first people settled prior to building of the dam and prior to the building of Boulder City.  The camp was also known as a squatters camp where the poorer famlies lived until better housing  came available. This area was also known as Government Survey Camp Number One during the actual building of Boulder City.  The lower portion of McKeeversville later became known as the Lakeview Subdivision which is active today.  The northern portion was abandoned and is listed as a ghost town in some records.  To many locals this was the other side of the tracks, as the railroad tracks ran between McKeeversville and the Boulder City township.  This area got its name from from a government cook who lived here with his family. 

McKeeversville Camp - Boulder City circa 1937-38

Today you can see remains of this Squatters Camp from the just completed River Mountains Loop Trail which passes along the edge of this camp.  Building foundations and walkways are still seen in the desert.  Old rusty cans, barrels, pipes and car parts in the area are relicts of the settlement.  Removal of these relicts is prohibited. Apparently McKeeversville ran up to the base of Red Mountain and into the area of Bootleg Canyon Park bike trails.

Volcanoes in the River Mountains

Volcanoes in the River Mountains ? – This phrase will certainly get the attention of locals who live in the area, particularly if you are not into the geology of the area.  This information certainly explains why the River Mountains are so rugged.  Since it has been 40 years since I took geology I’m going to reference material from Nevada Bureau of Mines and Geology Special Publication #16 ” Geologic tours in the Las Vegas area”.  

 

The River Mountains are composed of tilted and faulted mid-Miocene (15 to 12 million years old) andesite and dacite lava flows.  Two volcanoes, the source of most of the lava, have been identified in the River Mountains.  The first, located just north of Boulder city, is a stratovolcano surrounded by numerous domes.  Stratovolcanoes are cone-shaped features composed of lava flows interbedded with abundant agglomerate and breccia that formed from explosive eruptions.  The surrounding domes formed by the eruption of very sticky lava such as dacite, which erupted to the surface but did not flow.   Lava formed a low spine or a dome that quickly crumbled to a ring of debris about the dome.

The second volcano, located in the northern part of the River Mountains, is a shield volcano – a broad volcano composed of basaltic and andesitic lavas similar to those erupting today on the island of Hawaii.  

Both volcanos have been tilted, cut by numerous faults, and broken into numerous parts producing a jigsaw pattern of rocks that is now very difficult to recognize.  

This could have been River Mountains 14-million years ago. birth of a Mtn. range.

The following photo is of a cinder cone just a mile north and east of the River Mountains and can be seen from the trail between MM 12 and MM 14.  Locally it is called “Lava Butte”.

Desert Bighorn Sheep of the River Mountains

Desert Bighorn Sheep (Ovis Canadensis) – Range throughout the River Mountains an are often seen on or next to the trail.  Rams grow to 5 to 6 feet long, ewes grow 4 to 5 feet; study, muscular build; brown to tan with white belly, rump, muzzle and eye patches.

Rams have massive horns that grow over and behind the ears in a C-shaped curl.  Horns are permanent and grow incrementally year by year.  It may take 7 to 8 years for a ram to acquire a full curl. Ewes have a shorter, more slender horns that curve gently back.

The River Mountains are perfect habitat;  for the bighorn sheep occupy rough, precipitous terrain near sources of permanent water.  Bands follow regular feeding routes and maintain bedding grounds that may be used for years.  The desert bighorn sheep is Nevada’s state mammal.

The sheep population in the River Mountains is estimated at 200+.  In order to protect this herd of sheep the BLM has designated a good portion of the Northwest mountain range as an “Area of critical Environmental Concern” (ACEC) to help protect this productive herd of bighorn sheep.  Each year to keep this herd in balance the National Wildlife Service culls the herd by capturing sheep and re-locating into other mountain ranges in Nevada and elsewhere in the west.

The symbol or image used to identify the River Mountains Loop Trail is an image of a Bighorn Sheep on a mountain with the sun rising behind or the moon.  The sheep image is copied from the local rock art symbol for bighorn sheep used by Native Americans. This logo is used on maps, trail kiosks, trail monuments etc.

Desert Tortoise

Desert tortoise (Gopherus agassizi) – Nevada’s official state reptile, is the only naturally occurring tortoise in the Mojave Desert and is on the U.S. fish and Wildlife Service’s Endangered Species List. Over 6 million acres within the Mojave Desert, including over 1 million acres in southern Nevada, have been designated as critical habitat for the desert tortoise(areas that require special consideration and protection). This special consideration includes construction of tortoise fences in areas where highways or construction sites conflict with the tortoise life-style.
Desert tortoise are quiet and unassuming creatures, they spend most of their lives underground in winter dens and summer burrows where they are protected from the temperature extremes of the Mojave Desert. They are long-lived vegetarians, and are so efficient in their water usage that they can survive for more than a year without access to “free” water ( water derived from sources other than the plants that they eat).

The desert tortoise population has been decreasing in recent years throughout the western Mojave Desert.  One of the major factors in this decline is thought to be destruction of tortoise habitat by urban development.  This is especially critical in areas surrounding Las Vegas where the city is rapidly expanding into prime tortoise habitat. 

If you are lucky enough to see one of these elusive desert dwellers, DON’T TOUCH OR PICK IT UP.   They tend to lose water if picked up, to the tortoise it could be fatal to lose this stockpiled water.

Note:  The River Mountains is home to a large population of Desert Tortoise. The River Mountains Loop Trail passes through prime tortoise habitat and they are often seen near or on the trail.

White-tailed Antelope Ground Squirrel

White-tailed antelope ground squirrel

The White-tailed Antelope Ground Squirrel (Ammospermophilus leucurus) is gray with a narrow white stripe along each side.  The underside of its tail is white and is carried over its back.  One of the few small mammals to be active in the heat of the day, this animal is superbly adapted for desert life: 

  • It is omnivorous(feeding on both plants & animals) and prefers water-filled plants and insects.
  • It tolerates a nine-degree fluction (100-109 degrees F) in body temperature as it moves in and out of the sun.
  • It can salivate heavily and spread mositure over its neck and cheeks for evaporative cooling effect.
  • It can lose heat by conduction when it retires to the shade or is burrow and flattens itself against the ground.
  • It will postion itself parallel to the Sun’s rays and shade its body with its tail.

Editors note:  These guys in urban areas can become real pests digging up golf course greens and of course your lawn at home.

Cell phone coverage improved along Trail In Lake Mead Recreation Area

Nov. 20th – 2009 – Cell phone coverage enhanced in Lake Mead Area ….(this news brief was posted in The View this week)   Verizon Wireless expanded its network coverage and capacity in the Lake Mead National Recreation Area, enhancing a number of services for customers, the company announced. The move allows customers to make calls and send e-mails, text messages and pictures, as well as access the Web in a territory where services may not have been previously accessible. For more information, visit verizonwireless.com.

NOTE: Cell phone coverage has been an issue among some trail users.  This enhancement may bring improvements along that portion of the River Mountains Loop Trail within the Lake Mead Recreation Area . Alway be prepared and if traveling or riding alone let someone know where you are going and when you expect to return.

From a trail enjoyment and safety point of view we suggest cell phones be used for emergencies only.  Remember you are on the trail for peace and quiet; recreation; fresh air; so keep your mind and eyes on the trail ahead…..:)

Roadrunner – Beep….Beep

Greater Roadrunner – A member of the cuckoo family, the greater Roadrunner (Geococcyz californianus) is zygodactylous or two toes pointing forward and two backwards.  It has heavily streaked plumage, a bristly crest, short rounded wings an upward tilted tail, and long legs.  It rarely flies and has been clocked running at speeds up to 17 miles per hour.  It is said to have gotten its name in the Old West from running ahead of horse-drawn carriages.  Its diet of lizards, insects and spiders, small rodents, birds, and snakes is supplemented with occasional fruits and seeds.
