Update November 21, 2011. On October 4, 2011 the National Park Service announced that male mountain lion P-15 has been killed. It was  the first documented intentional human-caused death of a mountain lion in the Santa Monica Mountains. P-15's collar stopped transmitting on August 25, 2011. P-15 was was discovered on September 11, 2011, following a report of a dead mountain lion. The California Department of Fish and Game and National Park Service are seeking information related to the death of P-15 and the parties responsible. With the addition of $5000 from the City of Malibu the reward being offered for information leading to the arrest and conviction of the poachers currently stands at $16,700. The DFG Cal Tip Hotline is 1-888-334-2258.

Nature isn't necessarily nice. Behavior and interactions among animals are often violent. So it is with mountain lions. But the mountain lions of the Santa Monica Mountains also have to cope with the additional problems of living on an island of lion habitat in the middle of an ocean of urban sprawl.

The mountain lion tracks above were photographed on a run at Sage Ranch Park in late January 2000 . They might have been made by a young male mountain lion designated P3, whose territory encompassed this area. There is also a possibility there were from an older female lion, P4 that frequented the Rocky Peak area. Unfortunately both these animals were killed in late 2004 by eating prey (coyote) that had eaten rodents that had consumed anticoagulant based poisons. These poisons are used by parks, schools, golf courses and housing developments for rodent control.

The P3 and P4 pumas were tracked as part of a ongoing study started by the National Park Service in 2002 to learn more about mountain lions in the Santa Monica Mountains National Recreation Area. As of September 2011, twenty one mountain lions, P1 to P21, have been tracked, and their history has been quite a saga.

I was deep in thought, but have no idea what those thoughts might have been. It was at that point in a run when miles, and thoughts, flow freely. The afternoon was warm and calm and the settling sun cast a golden hue on the blond, oak-studded hills. My footfalls ticked out a steady rhythm on the dirt road, and my mind was at ease.

My reverie was suddenly broken by the realization that a coyote was running with me. Not running yards in the distance, or in the brush off to the side, but five or six feet in front of me, as if restrained by an invisible lead!

It must have come from the tall grass along the margin of the road, but from my daydream-warped perspective had just suddenly appeared. I'm surprised I didn't stumble or start. But there was no hint of aggression or malice -- just a mischievous glance backward to see how I was going to react.

I didn't. I've had numerous encounters with coyotes, but this went so far beyond my other experiences, I didn't know how to react.

For more than 50 yards the coyote ran with me, keeping pace in lead along the deserted dirt road.

At some point I started to try and retrieve my camera from the small pack on my waist. The out of synch movement disturbed the delicate balance of this improbable scene, and I could see the change in the animal's demeanor.

Before disappearing into the cover, the coyote looked back a final time, and in so many words seemed to be saying "gotcha, you're it!"

What the... Until I saw the water bottle and that the person was talking on a cell phone, I wasn't sure what I was seeing.

Then there was the rattlesnake -- well actually, the two rattlesnakes! Here's an HD video snapshot of one of them. This is an average size Southern Pacific rattlesnake. Because of our cool Spring weather they've been slow to appear, but are now out and about.

I almost always see mule deer when doing a trail run that passes through Trippet Ranch, especially in the morning. They tend to hang out near the parking lot, the pond, the oaks along Eagle Springs fire road, and along the Musch and Dead Horse trails.

Sunday several doe were grazing about five feet from the parking lot, and barely took notice as I (slowly) ran past. I also saw a buck near the start of the Musch Trail, but he was much more skittish, and strutted into the brush as I ran up the hill from the pond.

One of the largest Southern Pacific Rattlesnakes I've seen at Upper Las Virgenes Canyon Open Space Preserve -- formerly Ahmanson Ranch. This one was on the East Las Virgenes Canyon Trail (aka Main Drag).

I counted 12 rattle segments, and as this HD video snapshot shows, the snake was nearly as long as the dirt road was wide.

From a run on Wednesday from the Victory trailhead to Las Virgenes Creek.

Even though it was Summer, it was cold. Except for the clinking of our climbing gear, it was still and quiet at 13,000 ft. The sun had not yet risen, and I was perched on an icy step just below the bergschrund of Palisade Glacier. Tom had just crossed the large crevasse, and the brightly colored red rope ran through my hands as he worked up the ice of U-Notch couloir.

From our trail run on Sunday.

Part of the appeal of trail running is that even on a short weekday run, close to home, on a familiar trail, stuff happens.

The plan for today's trail run was a simple one -- run up and down the Chumash Trail in Rocky Peak Park. By the time we were done, a 5 mile run would morph into a loop of nearly 10 miles. We would encounter a rattlesnake and a longhorn bull, and we would run short on water. But we would also have a great run!

I've run in the Rocky Peak area for decades, and from time to time have encountered cattle near the end of Rocky Peak road. In recent years, the herd has been hanging out in the oil field and oaks between Las Llajas Canyon (near Poe Ranch) and a small mesa east of Rocky Peak road.

Seems to me most of the stock used to be Brahman, but these days there are many longhorns in the mix and according to an expert, these could be Longhorn, Corriente, or a Longhorn/Corriente cross.

When they heard us coming down the road most of the cattle just moved to another area -- except for the big guy in the title photo. He made it very clear that no one should be messing with his heifers. He was a little agitated. While he didn't charge us, it seemed possible he might. Avoiding any appearance of confrontation, we kept moving, and after a few moments were well away from the herd.

Deer seem to be plentiful in the Trippet Ranch area, and are frequently seen at this pond near the parking lot, or grazing among the oaks.

Running the Trippet Ranch Loop in Topanga State Park was a pleasant way to unwind after doing the Mt. Disappointment 50K last weekend. This 12.5 mile trail run from the End of Reseda is on a mix of fire roads and single track trail in chaparral and live oak woodland. I like to do the fire roads out to Trippet Ranch, and single track Musch and Garapito trails back. The elevation gain/loss on the loop is about 1800'.

Running up the hill to the Hub on the way out to Trippet Ranch we noticed some barefoot prints mixed in with the mountain bike and running shoe tracks. Based on the gait, the tracks were from a runner -- and from the speed they worked up the hill, the runner was feeling pretty good.

At the Hub the bare feet continued on our route, down Eagle Springs fire road, and about 10 minutes later they ended -- at a smiling runner wearing Vibram Five Fingers. Returning to running after a year and a half hiatus to start a family, Chris had recently read Christopher McDougall's Born to Run, and been inspired to try barefoot running.

Here's a Google Earth browser view of a GPS trace of the Trippet Ranch loop from Marvin Braude Mulholland Gateway Park at the southern end of Reseda Blvd., in the San Fernando Valley.

The thing about a dangerous situation is that you almost never see it coming. In an instant a pleasant adventure can turn really serious. We were in the San Gabriel Mountains about 2 miles down the little used South Fork Trail, and 20 minutes from Islip Saddle, when my running partner shouted, "Do you see that!"

From the tone of her voice I knew it was something serious. My first thought was a mountain lion, but then I saw it -- a bear cub clinging to a tree on the trail ahead. Sh*&! How many times had I told friends that I didn't worry too much about black bears, "unless, of course, it's a mother with her cubs."

Where was Mom? She had heard us coming down the trail, but apparently only had enough time to send her cub up the tree, and take cover. Not good, and potentially very dangerous. We couldn't see Mom, we couldn't hear Mom, but knew she was nearby. Most likely she was in the thick brush on the steep slope below the trail.

Suddenly, the cub scurried higher in the tree, its long claws digging noisily into the bark of the tree. That's when we saw that there were two cubs! The noise startled me, and I wondered if Mom -- wherever she was -- would react.

After a quick assessment, we walked quietly by the tree, and in a second or two started to jog. In a matter of seconds we were out of danger. It was fortunate that there were two of us and we were relatively noisy. A solo runner would have almost certainly surprised the mother with her cubs.

After a time the adrenalin subsided, and the rest of the run went very well. Temps were not quite as hot as expected on the low part of the course, and were pleasantly cool on Mt. Baden-Powell. Both the South Fork Trail and Manzanita Trail had been recently maintained. Some slides and washouts remain, but these are an integral part of the adventure and character of this trail run.

Update October 8, 2009. Here's a video of the cubs and Mom taken a couple of months after our encounter. The cubs have grown! It's from Cougarmagic.com, a video blog with  fascinating footage of mountain lions, bears, deer, bobcats, foxes and other animals found in the mountains near Los Angeles.

Observant, clever, mischievous and adaptable, the coyote often plays the role of Trickster in American Indian mythology.

This short Chumash story is from the course notes of an Introduction to Classical Mythology class at the University of Texas:

"Coyote begs to accompany the Sun one day, promising to behave himself. Coyote persuades Sun to let him carry the torch, and Sun warns him not to let it get too close to Earth. Coyote (of course) forgets, drops the torch, and almost burns up the world before Sun rescues it. Thereafter he stays meekly behind Sun."

When running in the Trippet Ranch area of Topanga State Park, more often than not, I see mule deer browsing among the oaks along Eagle Springs Fire Road, or along the Musch Meadow Trail.

On Sunday's Trippet Ranch loop, these deer were near the Musch Meadow Trail. The young buck appeared to be taking more than a passing interest in the doe. The breeding season for mule deer varies widely, and begins as early as mid-September in some locations.

Here is a zoomed view of the doe and buck.
