Punchbowl Canyon Feb 14

We awoke from a comfortable night's sleep in the Prius to some particularly chatty desert birds, high up in the enchanting Superstition Mountains outside of Phoenix. A quick breakfast and mostly quick packing prepared us for the short drive to our trailhead. I'd never been to this part of Arizona before and found the monument-like volcanic peaks and dense saguaro forests to be a refreshing change of landscape. We parked at the saddle near Black Cross Butte and walked down the switchbacked gated road into lower Fish Creek Canyon. Access to this canyon was formerly quite contentious as there were concerns of people walking the road all the way to Horse Mesa housing facility, but the canyoning organization CAC and the Salt River Project managed to come to a very favorable agreement to secure access. I usually don't enjoy walking on roads, but we did not see anyone else and the morning temperature was cool and comfortable. Before long we reached the Canyon Lake Reservior drowning what must have been a very scenic stretch of the Salt River. A very short walk upcanyon brought us to the dynamite shack where the steep and somewhat exposed "sheep route" to the start of the canyon begins. 

While the canyon was certainly excellent, this scrambling, ridge-clinging approach was one of the more fun and scenic canyon approaches I can think of and certainly added to the trip. We threaded our way up several short cliff bands, eventually reaching a steep gully. I was pretty sure we were on the route but surprised and how formidable the view looked from the bottom and the amazing lack of cairns and established trails. Once at the top, what appeared to be a crux climb with 100ft of exposure was actually a facade that could easily be scrambled around the back of.

From here we traversed a wide ledge with stunning views of some of the best volcanic slickrock I've ever seen. Crossbeded sandstone slickrock is certainly hard to beat but the colors, textures, and forms in this slickrock were excellent too. We continued up to gain the narrow and exposed ridge seen in the images below. Most of this was walking but there were a few exposed scrambling moves thrown in to keep things spicy.

Unfortunately the crude track I had marking this route was not terribly accurate, which led to a 20 min detour looking for a break in the cliff in the wrong direction. We did get to see some monstrous saguaros on the way though. Truly amazing life. Finally on the right track, we continued climbing our way up two more cliff bands and across an exposed traverse to finally top out.

With the climbing behind us, it was now a simple matter of traversing a sloping plateau and dropping into the head of the canyon. This plateau was a neat contrast to the steep terrain below and was actually completely coated in swirly chalcedony which had eroded out of hydrothermal veins in the volcanics. It was hard not to look at the ground and avoid walking into a cactus!

We dropped into the canyon easy enough and after about 10 minutes of scrubby wash, found the obvious place to suit up with our wetsuits. There was a pleasant light trickle and the sculpting of the volcanics by the water suggested good things downcanyon. Almost immediately downcanyon was our first of many pools and rappels. Although yes it was winter, we found the pools to be exceptionally cold!






Water did a superb job sculpting the volcanic rocks in this canyon. The canyon cut through many such layers, which each behaved a little differently leading to a nice variety of features- sculpted chutes, deep potholes, large drops, fun downclimbs.

        A great natural anchor. I'm sure we were not the first to use it.

This canyon had a nice length to it, good bang for our buck with the approach and exit. We maybe only counted about 7 rappels at this point and were told we'd find about 12 and, while we could see the reservior, we seemed to have a lot of vertical to go.


         The last narrows.

One final narrows led to an awkward boulder chute rappel followed by a beautiful lush hanging garden area complete with frogs and aquatic plants. An oasis in the desert. Just beyond was the dramatic horizon line of the final rappel, a ~120ft mostly free-hanging drop into a deep pool, the Punchbowl after which the canyon is named. This was probably the best rappel in the canyon and a great way to end it (frontispiece). A stone throw beyond was the road which would lead us back to our car. Once de-suited, the walk back was easy enough though I felt noticeably exercised after the day's adventure. Truly a beautiful area I look forward to returning to again.


Thanks to Sara and to those that came together to allow access to this beautiful spot.

Tucson Gem Show Feb 13


Every February since 1955 Tucson hosts the largest, oldest, and most prestigious gem and mineral show in the world. This is where the world goes to trade not only its gems and minerals, but also fossils, beds, jewelry, and art. It's not just one show but actually 43 separate shows that take over the city for a 2 week period. Enormous circus tents fitting about a hundred dealers are erected on vacant lots, hotels are booked solid and are shows within themselves (you walk from one dealer room to another like a potentially expensive game of trick-or-treat, vendors sell on street corners and abandoned gas stations, and the convention center is occupied with the flagship Tucson Gem & Mineral Show. This is where private collectors and museums display their prized specimens following the year's theme, and where those same private collectors go to shop for their new signature piece. It's not uncommon to see mineral specimens with price tags in the tens of thousands at this show.

It had been about half my life since I had last been to Tucson so I figured it was time for a visit. It's always fun to go and see what the new mineral discoveries are and I always find amazing wonders I never thought possible to exist. It's hard not to find something to take home, and this time around I actually had a shopping list of things to find for my mineralogy class.


We started at the 22nd Street show tent which had some impressive fossils for sale. The main prizes we found were a bit smaller and closer to our price range- classic pyrite from Nanjun, Spain, polished petrified wood slices suitable as coasters, a showy slab of green-purple Chinese fluorite. This was a good show to start with, though had Sara and I searching for an ATM before long.

Next we hit the rows of hotels west of the freeway: Quality Inn, Howard Johnson, and the Travelodge. These were good for large specimens and I found good examples of kyanite, magnetite, and rutilated quartz. These shows also had a fair bit I what I would consider junk, trying to appeal (probably quite successfully) to new age crystal healers, hippies, and hipsters. When I was looking at a dealer's nice Afghani pegmatite specimens and he realized they were out of my price range he pulled out a smaller piece at a price more difficult to turn down. One quick look and I knew it was a broken crystal that had been polished to look like the terminations were intact! Many dealers were pulling the same scam, though perhaps not quite so deliberately misleading, including one of the larger quartz crystal dealers. The main thing that caught my eye was some large and showy feldspar crystals, unfortunately the woman watching the booth didn't speak English and had no interest in selling the minerals.


        1 ton quartz crystal anyone?

Lastly,  we spent about 2 hours at the convention center show (frontispiece). We probably would have needed more time to see everything thoroughly but both felt overstimulated enough as it was when closing time was announced! Great displays (including some carefully guarded collections of great value) and incredible minerals for sale. Even saw a few faces I recognized.

We ended the day with some tasty Tucson-style Mexican food on an open air patio, then a few hour drive to the Superstition Mountains. It was a great weekend away, I'll hope to do something similar next year.

Ruby & Tataviam Canyons Jan 30-31


This was one weekend I certainly didn't want to find myself sitting around the office or office, regardless of the 1" rain forecast for Sunday, so I joined Alden and Dave for a couple canyons up Piru Creek, including a recently found classic and a first descent. After setting up the car shuttle at Lake Piru, we hiked in on an excellent trail from Oak Flat. As we gained elevation and approached one false summit after another, I began to realize we the first mile of our hike was all on a large landslide, extending from the crest above to the valley below, all through the Violin Breccia dumping off the ancient fault scarp at the edge of Ridge Basin- great geology! We maintained a solid pace to keep ahead of a large hiking group who set off at the same time as us. Reaching the saddle we gained a fire road, and followed it around towards the head of Ruby Canyon, before finding a reasonable (but still loose) ridge that would drop us into the drainage. This drainage seemed to be choked with stealthy (leaf-less) poison oak twigs...

        Dropping into Ruby (I see a landslide!) 

Once in the drainage we were mystified to find a well-trod trail with many fresh footprints. That is until we started to see abundant signs of illegal grow operations. The trail allowed good progress until just above the Ruby narrows (again suggesting non-hikers). These narrows (and indeed all of the two technical canyons we descended) were in the conglomerate member of the marine Juncal Formation. These first narrows were rather short and not very deep, but certainly well carved and a beautiful place.

         Short but sweet narrows of Ruby


These narrows gave way quite dramatically to the technical section, involving tricky downclimbs over large and smooth boulders. Despite being the third group down in a year, we were glad to see anchors in good shape, requiring little maintenance. As we continued downcanyon the horizonline effect improved. A couple awkward-ish rappels led to one 200' beauty down an amazing fluted rappel.



        Above and below: The standout 200' rappel


And the canyon continued. A further three rappels led to a final 160' rappel to the conglomerate/shale contact, signifying the end of the canyon. The view looking back up the canyon was impressive. With more time and many more spectacular floods, there is no telling what beautiful features would be created in this canyon.





A short stroll brought us to Piru Creek about 2pm. We unloaded camping gear, spare clothes, food, etc and began a rough and tough bushbash/scramble up the drainage opposite Ruby. This slowed us down some but we eventually reached the summit where a short descent dropped us to the start of our new canyon we named Tataviam after the Indian tribe that called the Piru area home.

A 40' downclimb brought us to a hanging pothole with just what we needed to rig an anchor down this large drop. Although I think we had higher hopes, the rappel was still quite nice with some excellent travertine formations- it would be a beauty after some rain. The second rappel which followed was more like 100'. Scrambling down a bouldery valley bottom, we soon encountered very fresh signs and abundant signs of illegal growing operations. We treaded lightly and a little on edge, but did not encounter anyone.



         The large drop with travertine

At the end of this section the canyon picked up momentum for a final 100' drop down into the Piru narrows. This was a larger drop than I was expecting and a particularly beautiful spot with flowing water, hanging pools, grottoes, and a final drop to the edge of Piru Creek right at it's narrowest spot. We were back at camp by a little after 5pm. We had a nice campfire to counteract the drizzle which had set in.



We awoke to solid rain to eat breakfast and pack our gear in. The air temperature now noticeably chilly. An avid outdoorsmen staying nearby stopped to say hello, and proved to be our fortuitous guide out Piru Creek to his car parked at the road end. This was a delight, saving us many hours of missed trail connections and the walk out on the long dirt road back to our car. What we thought was going to be a death march turned out to an easy 1hr20min to his vehicle. By the time we reached the vehicle the storm was in full swing with small landslides ripping of the steep shale slopes and normally dry creeks bursting to life. After completing the car shuttle I was left to brave the most perilous part of the trip: the drive through LA in heavy rain. Thanks to Alden, Dave, and our outdoorsmen friend for a great trip.
