Thompson Peak (Trinity Alps) 27/29-Jul-2017

Post by VanMarmot » July 30th, 2017, 3:55 pm

In 2015, Born2BBrad and I did a partially on-trail, partially cross-country figure-8 loop (trip report) around the Three Sisters in Oregon's Three Sisters Wilderness. In 2016, we did a similar on/off trail loop in Oregon's largest wilderness area, the Eagle Cap Wilderness (post). This year, we sketched out another on/off trail loop in the high country of the Trinity Alps Wilderness in Northern California.  Our initial plan was to start at the China Spring (or Gulch) Trailhead, go up past Grizzly Lake and over Thompson Peak (the highest point in this wilderness), then down the Rattlesnake Creek drainage, and back up to the trailhead via the North Fork Trail.  This particular trip didn't work out much as planned but it was still an adventure with a highpoint.

Day 1
Born2BBrad picked me up at my home, then we drove to Yreka, California, had breakfast (an unusual indulgence), and then continued on to the China Spring Trailhead {China Spring on one map, China Gulch on another map and at the trailhead?} at the end of Forest Road 37N07. We didn't depart the trailhead until 11:00AM and by then it was becoming evident that we were in for a HOT day on the trail. From the trailhead, we contoured south on the China Spring Trail (USFS #11W08) across China Creek through the remains of the 2006 Caribou Complex fire,

and then did a steep ascent [which used to be even steeper when the China Spring Trail started up the ridge from a lower, now abandoned, trailhead] some 1,200 feet to the top of the Salmon River divide and the former site of Hunters Camp.  From here we got our first look at snowy Thompson Peak in the distance.

After a cooling break at the saddle, we continued on the 11W08 as it did an abrupt 1,200-foot descent, through the remains the 2006 Bar Complex fire which burned on this southern side of the divide, to its junction with the North Fork Trail (USFS #12W01) above Grizzly Creek.

Here, we turned south and ascended the #12W01 toward Grizzly Meadow. By now the heat had turned oppressive and our water was running low. It was torture to hear delightful Grizzly Creek gushing along just out of reach owing to either brush or gullies.

It was a mercy to finally reach our planned camping spot at tree-shrouded Grizzly Meadow.  Except for a few downed trees, the trails from the trailhead to here were in good condition and easy to follow.

Despite the popularity of this hike, there aren't that many good campsites in this area and the only two people ahead of us on the trail this day took one of the larger sites near the creek. Fortunately, they were able to direct us to an equally nice site back in the trees. Which was good, because about three hours after we made camp, a party of six showed up hoping to camp on this spot - we directed them to another spot a little further up the trail.

The heat had taken its toll on us to the extent that we decided to modify our plans, as doing the original loop would mean descending to the infernally hot regions below 4,000 feet.  Instead, we decided to go higher and climb Thompson Peak, where things might be a little cooler.  But reaching the peak would first require us to reach Grizzly Lake via what the Forest Service calls the "Grizzly Scramble" - an obvious, but very steep, use trail up the side of the canyon to the left of 600-foot Grizzly Falls.

So, with a new plan in place, and the Scramble deferred until the morning, we gratefully called it a day.

Day 2
This day began earlier than expected when our camp was raided - not by bears - but by salt-crazed deer! They stole (and presumably chewed) Brad's underwear and bandana, gnawed the straps on his poles, and generally scattered the contents of his pack around our camp. I had all my gear in my tent which - despite noses poking at the fabric - allowed me to avoid Bambi-inflicted damage.  These deer were not afraid of us - trying to run them off only made them circle around and attack from another direction!

After securing our stuff from further depredation by deer and rodents, we tackled our first challenge of the day - getting back across the creek at dawn.

Immediately after that, we entered the boulder field at the head of the valley and then swung left and up on the use trail that is the Grizzly Scramble (and not a breakfast item at one of the Black Bear restaurants). It's truly a scramble (hands and feet needed) and it's steep - gaining about 1,000 feet in less than 0.5 miles. It also gets a little harder to find as the slope eases just before you reach Grizzly Lake.

Image Scrambling up the Grizzly Scramble

Once we got to the lake, it was immediately apparent why it's considered one of the most spectacular lakes in the Trinity Alps (if not elsewhere as well).  It fills the vast cirque beneath Thompson Peak, the highest peak in the Trinity Alps and the second highest in the entire Klamath Mountains. The Thompson Glacier (permanent snow field on the USGS maps) extends from the base of Thompson east toward Julius Caesar Peak and sends numerous large cascades tumbling down the granite cliffs.

Just on the other side of the lake's outlet, there are two jutting granite platforms that gave us a great side view of Grizzly Falls.

We sat for awhile enjoying the lake and scoping a route up Thompson's flank to the low point on the ridge from where we could traverse southeast to the summit.

A handy use trail didn't present itself, so we went west on granite slabs up the ridge just north of the lake and, at about 7,900 feet, turned south on to a broad bench that aimed us right at the low point.

We got about halfway to the low point before we had to start traversing up on snow - perfect spring snow on a moderate slope, great for steps with no slippage!

Once we reached the low point on the ridge, we had an excellent view of Grizzly Lake and a smoke-obscured view of Mount Shasta,

as well as one of the ridge we had to traverse to reach the summit.

It was here that things got a little dodgy. A lot of the beta we'd accumulated for this route was either too sketchy to be useful or (worse) wrong. We had been told that there was a use trail from the low point to the final summit blocks and there was, but it faded away about halfway to the summit. After that our instinct was to stay high on the ridge despite having to repeatly climb over or around an increasingly convoluted jumble of boulders. There are obviously many different routes here, but none are straightforward and none lend themselves to easy description. About 200 feet below the summit, Born2BBrad said he'd had enough of this thrashing and he'd wait for me if I wanted to go for it. Lacking his common sense, I pressed on. Nearer the summit it got steeper and I found myself making Class 3 moves out over the abyss. After two false summit boulders, I could finally see the next one was higher and (hopefully) the last one on the ridge. But it was across a gully, so I had downclimb about 30 feet and then back up to a nice scramble to get on top of the highest rock.

I had promised a quick go at this, so I got a shot of the nearest witness mark (there are at least five benchmarks and witness marks up here),

one poorly aimed shot of the Wedding Cake to the south,

and then retraced my route to rejoin with Born2BBrad. Yes, I got to the summit but not in the best style - it would have been better if we both could have gotten there and had some time to loll around and enjoy the view.  Staying lower on the ridge made our return to the low point go a lot faster and easier [Based on this experience and further research, it would have been better to have traversed 0.5 miles on the western side of the summit ridge, climbing only slightly and staying well below the craggy apex, until directly below the summit, then ascend a gully to the top.].

Now in full sunlight, Grizzly Lake was even more amazing as we passed it on our return.

Getting back required crossing the outlet of the lake on logs held together with tent cord and perched just 20 feet or so from the edge of 600-foot Grizzly Falls.

It had been cool and pleasant up on the peak (as we'd hoped) but was much warmer down in camp. So we turned in early in anticipation of a cool, oh-dark-thirty start in the morning. Two people camped near us that night and by then all the good sites in the meadow were taken.

Day 3
Once again, the day began early with a deer attack - not on us, our stuff was all secured by now - but on the camp next to ours. Our headlamps revealed a three-point buck contentedly chewing on what looked like someone's shirt. Trying to scare the buck away didn't work too well - he just dropped the shirt and started in on a pair of shorts! When we passed their camp on the way out, we could see our neighbor's (chewed) clothes strewn about and their packs all spilled open. We tried to wake them but there was no response, so we ran to save ourselves.

After that, it was just back the way we'd come, with a look back at Thompson,

another covetous glance at the waterfalls we'd wished we'd been able to easily access on the way in,

Image Another waterfall along Grizzly Creek

then up 1,200-feet and over the Salmon divide - surprisingly easy in the cool of the morning - and back to the trailhead. All told, about 19 miles roundtrip from trailhead to summit, with about 7,000 feet of elevation gain. Going out, we passed 16 backpackers (one group of 10!) and two dayhikers heading in and there were a dozen or so cars at the trailhead. Having been awed by Grizzly Lake, we can well understand why so many folks are willing to work hard to see it. We just weren't sure where all those people were going to find campsites?  Oh, and did we mention the deer...

Thanks VanMarmot for an outstanding trip report. I've long been curious about Grizzly Falls and your concisely written well illustrated, beta filled report grabbed my attention like no other this year!!!
I keep making protein shakes but they always turn out like margaritas.

Great report Bruce and another successful trip for the dynamic duo. I’ll tack on a few pics and some data geek stuff.

Nice work, guys. I'm impressed by Grizzly Falls, it looks like a Yosemite-worthy tier dropping off a horizontal granite cliff. So is the summit ridge on Thompson all rock only at the very top? (Some of the pics of the lower ridge make it look broad and sandy.) And Bruce - I just want to make sure I understand your TR correctly - what you're saying is that the fun way to the summit sticks directly to the top of the ridgeline, all the way up the summit block? ;)

Thanks!

Grizzly Falls is amazing - a 100-foot freefall followed by a 500-foot tumble down the canyon.

The summit ridge is pretty open from the low point to about halfway to the summit - this is about the point we lost the obvious use trail. We tried to follow the ridge line up from that point (as some hiking guides wrongly suggest) and got increasingly mired in boulders. So, from our perspective, the ridge on Thompson is a jumble of rock starting about 0.3 mi from the summit - and was not fun climbing. The actual fun/exposed scrambling doesn't start until you're within 100' or so of the top and interesting scrambling is required only to reach the true top (where the benchmarks are). The funnest way (from a scrambling perspective) to climb Thompson from the north via the low point would be to contour from there to below the summit and then ascend directly up one of the gullies - I think you'd find plenty of fun scrambling there. Or you could contour around below the summit blocks and approach them from the southeast - similar to what folks coming at Thompson from Canyon Creek would do. Either way you'd preserve your route finding energies for the fun stuff near the summit rather than expend them clawing your way through 0.3 mi of boulders!

Thanks! We were surprised at its popularity, despite the hike in. So try not to go on a weekend as there aren't that many good campsites at or near Grizzly Meadows. If you just wanted to visit the Falls and the lake, one option would be to camp at Low Gap Campsite (huge, flat, shaded sites right on Grizzly Creek) and do an out-and-back dayhike to the lake from there. Some people do the lake as a dayhike from the TH but that amount of effort is now above my pay grade! :shock:

Wow EPIC!!!!!!

Next year idea: Canyon creek to mirror/emerald/sapphire. Both sides are AMAZING!!!

Trinity alps miles feel like 2x Mt. Hood miles as that granite just beats you up!!!

Thanks for posting, always wondered what that summit pitch was like, have not been down there in years however.

Wayne Moss has a great book if you've not seen it, has color images: The Trinity Alps Companion. Great book to bring along!!

Great report! The Trinities are tough. All the trails are seriously steep. Your elevation profile says it all! Van M., your scramble on the peak makes me think you are taking your name a bit seriously....... (My portrait is a goat but its aspirational - I'd be with chillin' with B2BB. :lol:
