Temecula Gorge Jan 21


Nine miles of quality (mostly) wilderness Class III-IV river thirty minutes from Riverside?! It does not happen often but when it does it is quite a sight and not to be passed up. Murrieta Creek and Temecula Creek join to become the Santa Margarita River and then within about a hundred feet enter the dramatic (for southern California at least) Temecula Gorge. Despite uplift of the Santa Ana Mountains and Santa Rosa Tablelands from the Elsinore Fault, the Santa Margarita River has persevered, matching the uplift with vigorous downcutting to create the thousand foot-deep bedrock gorge. The first kayaking descent was in 1998 and it has received relatively few descents since due largely to the fickle nature of the river. Windows of boatability for this drought-stricken region can be years apart (last running in 2010?) and last hours or days at best. Mine was likely the first packraft descent of the gorge.

The stream gauge peaked at nearly 6000 cfs the night before from the second of three storms and Keith and I watched its descent with careful interest. In the morning we awoke to find it running at 578 cfs and dropping 87 cfs/hr...fast. We quickly mobilized, set the shuttle, and met Chris from San Diego (who would be joining Keith and I) at the put in: a muddy park-and-ride lot next to the highway next to an Arco next to particularly trashy stretch of foamy creek. Humble beginnings I suppose. I tried not to think too much about the contents of the foamy water which drains a sizable chunk of the Inland Empire.


The creek was at about 400 cfs when we put in with no sizable contribution from Temecula Creek. Fast moving water took us from the Arco to the gorge mouth in a minute or two. Nearly every willow and thicket had flood debris and trash several feet overhead, marking the previous day's high flow. Right off the bat we found the woody debris choked several of the channels, requiring swift thinking and careful route finding to avoid unpleasantness and danger. Many of the ways through were just over a boat width with branches partly blocking the way. At one of the first major drops I managed to catch the pool wrong and executed the first of three flips. My newly installed thigh straps and seat system worked beautifully and I really appreciated the added control and dexterity.




The vegetation also impressed me. Here was a rare view of preserved southern California: rocky outcrops coated in native dudleya succulents and prickly pear cactus, the river's edge coated in sycamores and oak trees (marred only by the foreign willows and regretfully native poison oak). A couple waterfalls dropped to the water's edge. We even saw beavers! We had it all to ourselves to enjoy.

We made steady progress and generally worked well as a team, jumping eddies and alternating our scouts. This creek was steep! Occasionally the view downstream was of a distant and much lower river, with unknown drops and debris in the foreground.  Because of the low flow and woody nature we ended up scouting quite a bit (perhaps a dozen times) and opted to portage about six times. Since I had canyoning shoes I made many of the longer scouts and got to lead many of the more fun runs.I also made a few of the bolder read-and-runs, usually ending up where I wanted to.




The deeper we got the more bedrock, steeper the rapids, fewer the graffiti, but equally abundant the stranded floatsom trash- clothes, suitcases, tarps, golf bags seemed especially abundant. Occasional we would see hints of the old railroad which ran through this gorge, briefly, before its inevitable demise. It's really quite telling how dynamic this gorge is based on how little evidence for the railroad is still left today.

The gorge was excellent- really great continuous fun. Unfortunately we were beginning to notice the drop in water (it would be nearly 200 cfs by the time we took out!) and all were hungry but did not really have the time to stop. So we powered on, around the sharpest and deepest corners in the canyon and the final stretch of the gorge to where it opened up with views of citrus and avocado fields.



A few more sizable rapids followed but Class II stretches predominated, and so did willows and woody debris choking the channels. Occasional we were lucky with some narrow side channel that just barely went through. Other times we were not and had to fight the hard way by portaging around long unpleasant stretches. I made a crucial error and took a lengthy swim through a debris filled channel that would have been dangerous with more wood or water. Good, humbling practice I suppose.

Eventually (and with the water continuing to noticeably drop) we started seeing graffiti again, and then families out walking the riverbank, a sure sign we were getting close to our takeout. Once there I was amazed to notice a barely recognizable river. With most of the remaining river in a channel towards the north, we walked boats across a dry channel at our takeout that only hours earlier held a raging river. We made it and not with a drop of water to spare! We got to enjoy a remote place of southern California in conditions few people get to see. It was beautiful, it was fun, and it was a satisfying run, as good as some of the creeks in the Sierras. So much of southern California has been altered by man. It's great to see a place that can shed attempts by humans to tame and stay wild, even if only for brief moments in its long history. Thanks to Keith for leading the way and Chris for joining us. I hope to do it again at higher flows and maybe to tackle some of the interesting canyons along the way.

Great Falls of the Fox Canyon Jan 14

Presented with a three-day weekend at the end of a solid bout of rain in southern California I figured I could spare one day to be out and about. I had never been to Great Falls of the Fox, said to be one of the standout canyons in the San Gabriels for its narrow bedrock canyon and rapid-fire waterfalls, so thought this would be as good a time as any to check it out. It was my first time in the Big Tujunga area- spectacular outcrops of previously unmapped rock avalanches and slumps made me a distracted driver and reinvigorated my geologic interest in the San Gabriels. A quick scout down the road suggested manageable water levels in Fox (less than we thought) and so we set off from the car at about 8:30a. 

We followed an old fire road down to Big Tujunga, crossed the swollen creek on logs to preserve dry feet, and then climbed the longer fire road up the other side. About two hours in we turned off from the fire road and almost immediately encountered another group of six canyoners. We quickly passed this group (destined for a post-sunset exit from the canyon) and traversed the steep slope and gully into Fox. For a "navigationally tricky bushwhacking traverse" it was intuitive and straightforward. I was pleasantly surprised. The creek had a nice enough flow and we crossed back and forth, traversing a minefield of logjams, and as I am just now finding out, poison oak. After a number of minutes, bedrock started appearing in the stream channel and it was time for a snack and to suit up.

The canyon started with its first rappel a stone throw down. From here on it was a nice section of canyon with eight closely spaced rappels. Several were quite beautiful and most put us right into the meat of the flow. The meat however was lean enough that there were no hydraulics to avoid. A splashy good time, but no sign of real danger.





The hundred-foot Great Falls (photos below) was certainly noteworthy. A smooth enclosing chute of rock with whitewater plunging into unseen darkness below. The anchor was well placed to allow us to go right through the main part of the flow. I enjoyed it so much I had to jug back up (enduring severe brainfreeze) and rappel it again.





Two more rappels followed, each offering dramatic upcanyon views of the Great Falls beyond. In times past (before the 2009 Station Fire) several of the pools at the base of the falls would have been swimmers, even jumpers, but in its current gravel filled state we found only shallow landings. The recent rains were not the right flow to scour the canyon, only further fill it with gravel.



About forty minutes of Eaton-esque stream walking brought us quite abruptly to the final seventy-foot rappel. This one had a nice broad sheet and clearly would have been impressive at many times more flow. A short distance below we began to see sediment banks related to Big Tujunga Reservior's full pool, and shortly thereafter the Big Tujunga River.


We found the exit track back up to the highway surprisingly well traveled and made quick time (other than my occasional stop for geologizing). A half-mile walk along the highway and I was delighted to find my car where I left it (one of the other group's four car was apparently not so lucky). A little over seven hours car to car. More than most canyons in the San Gabriels, the canyon had its nice moments. Two mylar balloons were the only sign of human trash on the way through. Thanks to Keith for a nice day out. I'm now even more motivated to scour the San Gabriels for large lurking landslides.

Carrizo Gorge Jan 1


Tucked away in eastern San Diego County just above the Mexican border is an interest stretch of railroad, a forgotten feat of engineering that just was not meant to be. Carrizo Gorge is a 12 mile-long rugged granite and gneiss valley that is hardly the place you'd expect to find a railroad. Yet the San Diego and Arizona Eastern Railway cuts through here with a near continuous chain of tunnels (up to a half mile long) and trestles (including the longest curved wooden trestle in the world). The stretch of rail was completed in 1919...and a crucial tunnel collapsed in a 1920 earthquake! The Goat Canyon Trestle (frontispiece) was then built to bypass this tunnel and span Goat Canyon. A patchy history of use and disuse (destruction followed by repair) ensued. As recently as 2007 the rail line was closed to the public with plans to repair and reuse the line. For the present moment the rail line is inoperable with abandoned derailed cars spanning the tracks and collapsed tunnels, making an amazingly wild mountain bike ride, 99% on single track or grates adjacent to the rails.

 

When we pulled up to the park spot it was clear we were not the only people that thought this would make a great new year's day activity. Over the course of the day we saw four different groups of hikers and one mountain biking group. I was pleasantly surprised the locals seemed quite friendly with most waving as they drove past our car. After adjusting seats and lubing chains we set off along the foot-wide singletrack adjacent to the tracks. Occasionally we had to dismount to cross a trestle without a side path, but generally the route was remarkably rideable. A short distance on we reached some interesting vandalized passenger cars derailed across the tracks. Quite a surreal sight. A little further was the first of many short tunnels. The further on we went the deeper the canyon, the better the scenery and the more impressive the tunnels and trestles.



It's hard to say whether I liked the tunnels or trestles more. Probably the tunnels. Two of them approached a half mile in length and needed headlamps. The amount of concrete and shoring that went into these tall tunnels in truly impressive. The tunnels were also probably the smoothest travel. And each was a little different.

Progress was slower than it ought to have been so we settled our sights on having lunch at the Goat Canyon Trestle. This was a truly impressive feat of engineering. I biked across the grates, avoiding the occasional hole. Sara and I ate lunch in an abandoned box car to get out of the wind for a bit. On the way bike I decided to walk the bike which was actually much scarier than riding it. When riding the bike you look forward- on the grate material that means you see a rather solid looking surface. When walking the bike you look down at your feet, looking through the thin grating and realizing just how precarious this pile of wood and rust is! I wonder how many more years it has until it collapses. Maybe the region's next big earthquake.




We returned the way we came without incident. We passed a few groups and were passed by a group of bikers. Eventually we made it back, about 15 minutes before drops of rain. I was happy to find the car intact and where it should be. I'm glad I finally got to check out the gorge if not the entirety of it. It's certainly a unique and fascinating place.




We drove on to El Cajon to stay the night with my grandparents. Thanks to them for a great visit and a great end to a few days of local adventuring.
