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.

Big Horn Sheep near trail at risk?

 OCTOBER 12, 2009 – I have received many searches for Big Horn Sheep. This recent article by Jean Norman along with related photos really provides some great insight to the some of the issues these big boys face on a daily basis.  I personally prefer to see them out more in the wilds along the trail which is a rare sight indeed.  This park location where the sheep are photographed is only a block off the trail so one can make a quick side trip while riding trail through Boulder City.  The park is located off of Ville Drive and is called the “Hemenway Valley Park”.

The desert bighorn sheep that live in the River Mountains in Boulder City, seen here on a recent weekday morning, make their way down to Hemenway Park almost every morning. City officials have voiced concerns about the sheep as traffic in the area they roam is set to increase next year with the opening of the new Hoover Dam bypass bridge.

Desert Big Horn Sheep use the trail, too…

The River Mountains Loop Trail is home to many users groups. The oldest users were here long before the trail was dreamed of.  The photos below were provided courtesy of Paul Grebe, Green Valley Cyclist and a RMLT member. Photos were taken November 24th around milepost #15. These three Rams have seen some years as the horns are nearing full curl.  There have been reports of other sightings along the trail by other users.
