12338 from the SWThe south face of 12338


This page describes a route to Peak 12338, the northernmost peak of the Red Castle Ridge found in the Uinta mountains of Utah. Peak 12338 is remote, rugged, and sees few ascents. It looks intimidating, but there is a class 3 route with minimal exposure up its south face. From a distance it appears steep and composed of loose rock, but it's not so bad close up. It is not technically difficult, but is an interesting navigational challenge as small cliffs abound and you often do not get a view of where you are heading. When you do get to see ahead, it is not clear what is the summit until you are almost to it.
S face of 12338Hmmm, should I angle left or right?
South face of 12338Some dirt

All but .8 miles of the route are on an easy to follow, well maintained trail. There are no difficult creek crossings. The three major ones are bridged. Of the remaining .8 miles, .6 are either easy cross country travel or are standard boulder hopping. It is only .2 miles out of 11.8 that present any difficulty. But, in these .2 miles, you will climb 938 feet.

The words loose and stable are subjective terms. There are loose rocks scattered all around, but it was always easy to choose a stable place to put my feet. I never felt like I was fighting gravity. The ascent is a mix of dirt with rocks sprinkled through it and 4-6' mini cliffs with tons of nice solid foot and hand holds.

Getting There

The route starts at the China Meadows Trailhead, located about 4 miles west of Henrys Fork, the major gateway to Kings Peak, the highpoint of Utah. For driving directions see the Getting There section for the main page.

Route Description

Start from the China Meadows Trailhead. Follow the East Fork Smiths Fork Trail 9 miles to where it forks to bypass Red Castle. You will be in the woods most of the way and only gain 1300' in elevation during this stretch. The trail is well maintained, easy to follow, and has generally good footing.

12825Heading to E Red Castle Lake

At the 9 mile mark is a sign that points left for "E Red Castle Tr." and right for "Red Castle Tr.". You want to take the left fork and immediately cross a bridge. Go another 2 miles to a small stream at N40 47.997 W110 27.033. The East Red Castle Trail crosses the stream and continues to Smiths Fork Pass. Instead of doing this, make a right turn onto a small path just before the stream and head to the far end of East Red Castle Lake. The path fades out but it is easy cross country travel to the lake and around to the other side. There are several other small lakes in this vicinity.

Cliff breakCliff break

The base of 12338 is ringed with cliffs, but there is an obvious cliff break on the south side which is your immediate goal. Upon reaching the far end (west side) of East Red Castle Lake, work your way to this cliff break found at N40 47.916 W110 27.566. This section past the lake, is composed of annoying to walk on boulders. Note the cliffy sections on the right half of the left picture. Stay to the left/west of them on your way up.
Now comes the interesting part, ascending the 42 degree slope to the summit. You will climb 938' in .2 miles. At the cliff break there is only one obvious way to go, up and to the right. Above the cliff break I angled left to avoid the cliffs on the skyline. After this, there are many choices available to you and the rest of the route could be summarized in eight words. "Just go up and hope for the best." Often, you can't see very far ahead, and when you can, it's not clear which way the summit is, but as you close in, the top of the pillar comes into view.

South face of 1233812160': Head for pillar
I had some waypoints preset that I was planning to loosely follow, but I wound up ignoring them and just zigzagged back and forth by whatever way looked good until I hit the summit block. Perhaps this method will work for you too, but in case it doesn't, I have included some waypoints with the map (below) for the way I actually went. Do not expect to be able to pinpoint exact locations, but you should be able to use the waypoints as a rough guide. See the section on GPS use below.

With careful route finding, you can find your way to the top using only class 3 moves. However, you can make this as hard as you'd like and it would be easy to venture into class 5 territory if you wished. But, there are always lots of options and I never had any difficulty finding a way I was comfortable with.
12338Summit and Pillar

I wound up just a little SE of the summit at the pillar shown at left. Directly ahead was an almost vertical wall (15' or so), with an obvious break which I'm sure some one could scramble up, but that some one is not me and I opted to find an easier way.

Base of summit cliffsLooking back

I traversed west at the base of the cliff towards Red Castle. The base is amazingly wide (10' or so) and is very comfortable to walk on.

At the southwest end of the summit block I found a very nice easy scrambling break that went to the summit ridge.

Once past the break, the last little section is just an easy walk to the top.
E Red Castle LakeHeading down

To return to the base, you might be successful if you just head down. However, the thought of getting stranded on a ledge overnight in below freezing temperatures was particularly unappealing to me, so on the way up, I set up some very small 3 stone cairns that I knocked over as I descended. Perhaps the cairns were overkill, but I was assured of not getting stuck. There were several sections that I would have sworn I did not come up were it not for seeing the 3 little rocks at their bottoms. Just as on the way up you can't see very far ahead to pick your route, it is the same going down. Although you can see stuff that is miles ahead, you can only see the ground ahead for a short distance so it's hard to pick a good way down.
The following are some views you'll get while climbing. You will see Mount Powell, East Red Castle Lake, Smiths Fork Pass Lake, 12407, 12825, 12566, and 12700.

Essential Gear

I wore a helmet, but other than that, just normal hiking gear is needed.

Notes on GPS use

If you intend to rely on a GPS, you had better know what you are doing. Unless your GPS has a built in compass (most don't) you can't just follow the arrow when moving slowly and you will be moving slowly. GPS's work great at pinpointing locations on flatish terrain. They don't work so well when blocked by a steep slope. Reception may be spotty and the arrow will be jumping around. You need to observe where on the GPS's compass ring the arrow is pointing (e.g. NW) and head in that direction (i.e. go northwest) even if it is the opposite way from where the arrow is pointing.

You should be able to use the waypoints as a rough guide, (e.g. is a waypoint to the left or right of you) but don't expect to pinpoint each location.

When to climb

In most years, mid June through the end of September will work. The mosquitoes go away by the end of August and the people pretty much clear out after Labor Day. On the day after Labor Day, a Tuesday, mine was the only car in the parking lot and I saw no one all day.
