Mud Hills Wash to Elephant Knees | ABDSP


On New Year's day, 2015, I was able to get out of town for hike through Mud Hills Wash, which would be hike #2 of my 52 Hike Challenge.  This five-mile route, in the desolate Carrizo Badlands of Anza-Borrego Desert State Park takes you through the magical mud hills on the edge of the badlands and up to the top of the Elephant Knees mesa where you can see the vastness and density of the area's oyster shell reefs. This area is so dense with fossilized shells and shell fragments that they seem to outnumber the materials in which they are embedded. The view is one where you can take in much of the Fish Creek drainage and trace its geological history.

"This is the desert at its lowest, hottest, and- to the unappreciative eye- most unfriendly. To those who know it well, however, it is a fascinating labyrinth of rugged canyons, twisted arroyos, and mud hills, containing not only some of nature's best examples of earth sculpture, but also a complete sequence of animal fossils. In truth, it's not unfriendly at all. Even the weather is beautiful- at least from late fall into early spring." - Jerry Schad, Afoot & Afield In San Diego County

To get to the desert I have to drive through the mountains, which usually isn't an issue. However, with the recent snowfall, I knew the crowds would be flocking to the higher elevations of the county. I was getting a late start so to avoid getting caught in the bumper-to-bumper traffic heading up the highways, I took Boulder Creek Road. This mostly graded dirt route would allow me to bypass the majority of the traffic.

As the route climbs, I begin to see this seldom seem white stuff on the hills above.


Looking west towards El Cajon Mountain, informally known as "El Capitan." Beyond that I could also discern the faint outline Cowls Mountain, the highest point in the City of San Diego.


This route takes you through Cleveland National Forest. This sign is located at a hairpin turn in the road and the trail heads for Eagle Peak and Three Sisters Waterfall.


Snow covered mountains of Anza-Borrego Desert State Park come into view as I make my way down Banner Grade.


Eventually, I reached Ocotillo Wells SVRA, turned south on Split Mountain Road off Highway 78, and onto the sandy wash of Fish Creek, which is typically dry and firm in late fall and winter but possibly slippery with mud following a major storm. Ahead looms Split Mountain, with cliff-like walls that occasionally shed rock debris onto the trail below. I make a quick stop at the dramatic thumbprint-shaped Anticline- ancient sea floor sedimentary layers that were pushed and buckled by an earthquake eons ago.


Parked in Fish Creek, along with a number of other folks out enjoying the day.



Mud Hills Wash begins just around the bend from the Windcaves trail. It comes into the main fork of Fish Creek 0.3 miles west of the Windcaves trail marker. There is an information panel on oyster shells reefs on a knoll next to it (west side).


Parts of the wash were still muddy from the recent rains. My guidebook said that you'll accumulate about two inches of mud on your boots if its wet, but that's all part of the fun.


Walk past the "Closed to Vehicles" sign and follow the meandering path of Mud Hills Wash into the maze-like badlands. You may see such things as glass-like gypsum crystals, loose shells, indications of recent flooding (mud flows or mud curls) and lots of fragile plant life along the trail. Keep in mind that no collecting of fossils is allowed in the state park.



As you wind along, you should be able to keep the flat-topped Elephant Knees mesa in view. Keep following the main wash around to the right (west) as the object is to get to the backside slope of this formation, which you should arrive at in 1.5 miles.




Making my way around the mesa, through the mud hills.


Falling into one of these would probably ruin my day.

Here is where I began my assent to the top. These massive blocks are part of a 12 to 15 foot thick Oyster Shell reef embedded within the butte, left behind when it was still a part of the Gulf of California. Although the climb was very steep at times, it provided good traction, but its also razor-sharp, so I had to pick my way carefully.

Looking back at my route up the butte.

Looking southwest across the badlands with Carrizo Mountain in the distance.

Looking west, I can make out the distant conical shape of Sombrero Peak.

At the lip of the Elephant Knees formation you will be able to look down at the knees and the point at which you started your walk- and a large portion of Fish Creek Wash with its surrounding hills and mountains.

Selfie at the top!


After taking in the views, I make my way along the lip of the mesa and back down into the mud hills. Walking along the edge was definitely exhilarating and the highlight of the hike.


Last look at the Elephant Knees as I make my way back to Fish Creek.


Moon rise over the mud hills.

Arriving back at my Jeep parked along Fish Creek Wash.

On the way out I stopped in the narrows of Split Mountain, along with a few others, to enjoy the views.



Some of my earliest and favorite memories of camping and exploring this area are here with my parents back in the 1980's. It was a great way to start the new year and I'm looking forward to getting out again soon. If you are interested in geology, fossils, or amazing desert terrain this area is a must see. Happy trails everyone!



GETTING THERE: To find Mud Hills Wash, drive east on Highway 78 to Ocotillo Wells and turn right on Split Mountain Road. Drive south 8 miles until you cross a dry creek bed with a sign indicating Fish Creek Wash. Turn right (west) onto the dirt road leading into the wash and follow it 4.5 miles, bearing to the left at the Windcaves trail marker to remain in the main wash.



At 0.3 miles you should see the Oyster Shell Wash information panel, where your trek begins. Most times of the year the road into Fish Creek tends to be accessible to 2-wheel drive vehicles, although 4-wheel drive is always recommended. Check at the Visitor Center for road conditions before setting out on your adventure. As you travel along Fish Creek Wash on your way to the beginning of the hike you will be going through Split Mountain Canyon, which in itself is worth taking the time to see. Some people may prefer to begin their walk through this area beginning at the Fish Creek Primitive Camp. Doing so would add another 5 miles to your hike (round trip).

Carrizo Mountain & Yuha Basin

(Campsite below the summit of Carrizo Mountain.)

Since the upper reaches of Painted Gorge and Carrizo Mountain are closed from January 1st to May 31st due to a seasonal bighorn sheep closure, I planned on camping near the summit over the weekend of the 15th and 16th of December, 2012 with my wife and daughter. Along with exploring old mining roads around the mountain, I also searched for fossilized wood near the Plaster City area and explored the fossilized oyster beds of the historic Yuha Desert. This area is located just outside the Anza-Borrego Desert State Park on BLM land. It was great spending some time in one of my favorite areas of the Southern California desert and relaxing around the campfire with my family. 

The beginning of the route to Carrizo Mountain starts on Painted Gorge Road along Highway S80 and passes through Plaster City OHV Area. The graded road soon becomes a trail as it nears the sandy wash of Painted Gorge and quickly enters the canyon. Embedded rocks litter the wash, which eventually turns into a very narrow, rocky, loose shelf road as it nears the summit of Carrizo Mountain. There are great views of the Yuha Desert and Salton Sea along this trail.

Painted Gorge / Carrizo Mtn Trail



Desert USA has the following to say about Painted Gorge, "The Painted Gorge, located on the eastern side of the Coyote Mountains, consists of sedimentary, metamorphic and ingenious rocks. Heat and movement over time has created fantastic shapes and colors. Oranges, reds, purples, and mauves mixed with browns and blacks create a palette of color as the sun illuminates and plays shadows upon this geologic wonder called the Painted Gorge."

Hoping the weather clears up by the time we get out there.

Things are looking good!

Carrizo Mountain is the highest point of the rocky Coyote Mountains, located in the transition zone between the Salton depression of Imperial County, and the mountains and desert valleys of the Anza-Borrego Desert State Park to the west. The range is located not far north of Interstate-8 near the small community of Ocotillo.

This is what happens when you get lost...

The things we find in the desert. This would make a good camp chair, right?

Watch out for all the weirdos up here!

It turned out to be a cold night, so we all enjoyed the fire.


Sunday morning.


I think she's ready to go!

Stopping to check out another potential campsite.

Heading south on Painted Gorge Road.

After crossing under Highway S80 we part part ways with Steve and continue on towards the Yuha Basin with Patrick.

We make our way along the old State Highway, being careful to avoid the collapsed sections. I love exploring old abandoned roads.

The original paved road dates to 1915 and was only 15 feet wide, but paved with Portland Cement. This is unusual for a desert highway since asphalt is better suited to accommodate the temperature extremes associated with the desert climate. This road was surpassed in turn in 1932 by a wider road, U.S. 80, this time paved with asphalt. Both alignments remain today and can be easily seen.


Crossing under Interstate 8.

Making our way into the remote, seldom traveled Yuha Basin.

Yuha Basin Map


The Yuha Desert of extreme Southern California is rich in both human and natural history. The area contains several unique attractions; the Juan Bautista de Anza National Historic Trail, geoglyphs created by Native Americans, an area of rare crucifixion thorns, oyster shell beds, and the Yuha Well. The Yuha Desert is an Area of Critical Environmental Concern and is a limited use area. Please observe all posted signs. Routes traverse a variety of terrain, from flat desert pavement to sandy washes, to mud hills and other badlands type features.

The Yuha Buttes.


We soon find ourselves surrounded by low lying hills covered with fossilized oysters and ancient reef beds.

My little helper.



The larger oysters were found in the lower areas of the wash.


All too soon it was time to make our way back to civilization. 


Following the route that would take us back to the freeway.

These were a prominent sight from pretty much where ever we were.

One last look back towards an area that'll need to be explored much more.
