Skirting Iron Mountain - August 24, 2007

The southern part of the Ritter Range does not offer as many spectacular climbing routes as its more popular northern end. Nonetheless, the lakes and passes that characterize this region provide ample opportunity for some really enjoyable cross country hiking. Even experienced peak baggers will find something of interest; Iron Mountain is the high point of the area, and several of its approaches appear interesting and challenging. We visited the Iron Mountain area on a day trip from Mammoth Lakes: by car to the Devils Postpile trailhead, by trail to Fern Lake, then cross country towards Holcomb Lake, including a side trip over the Ritter Range crest, and finally back by way of the Beck Lakes trail. An unknown total distance, but I would guess, around 20 miles.

Peaks above Anona Lake from the King Creek trail.

8:15 am
We started at about 7:30 am from the Devils Postpile Ranger Station trailhead, and took the King Creek trail. Some 45 minutes later, we could see from the trail, for the first time, the peaks above Anona Lake (center and left).

 
Anona Lake and Iron Mountain crest.

9:30 am
Fern Lake is about 5 miles from Devils Postpile. The trail has one steep uphill portion, but it is interesting and well maintained. In contrast, the trail between Fern and Anona Lakes becomes faint and then completely disappears. However, with a good map, it is easy to find your way around. From the small hill just east of Anona Lake, a view of the lake opens up (lower right corner), and the peaks of the Iron Mountain crest begin to appear. Anona Lake is at the 9100-feet level (2773 meters).

According to Robert (R.J.) Secor, The High Sierra: Peaks Passes and Trails, there is a class-2 route from Anona Lake to the crest, but we looked...

...and looked...

...and looked, and didn't see any easy passage over the rocks surrounding the southwest shore of the lake. Perhaps next time, we'll actually try, not just look.

 
Snowfield at Ashley Lake.

11:15 am
A cross country ascent, with some simple rock hopping and route finding, brought us to the Gertrude Lake plateau, and then to beautiful and remote Ashley Lake.

Early in the season, the snowfield on the left usually extends all the way down to the lake. Jules Eichorn and Walter A. Starr (Sr) were the first to use this snowfield to get to the top in 1935.

Note added: In July 2008, Dom and I came back to this area, and climbed to the top of Iron Mountain via the Ashley Lake snowfield.

 
Iron Mountain above Ashley Lake.

The summit of Iron Mountain (11148 feet; 3398 meters) above Ashley Lake (9543 feet; 2909 meters).

We walked to the opposite side of the lake, then followed a stream uphill to a charming valley hidden in this picture by the ridge on the right.

 
A low pass to the west  side of the Ritter Range.

At the top of the valley, we see a low pass to the other (west) side of the Ritter Range, which we can't resist (center of the picture).

(See topo map showing our skirting around the edges of Iron Mountain).

 
Near the top of the pass.
12:15 pm

Near the top of the pass. The valley is below us, and Ashley Lake can be seen at the right edge. Mammoth Mountain dominates the view to the east.

The pass seems to be unnamed, but I will refer to it as "Ashley Lake Pass". It tops at about 10600 feet (3230 meters). Could be described as a simple class-2.

 
The other side of the pass.

The other side of the pass is simple class-2 again. This is the view south, towards the Iron Lake creek. Iron Lake itself is hidden behind a ridge.

 
Mountains on the Yosemite border to the west.

We dropped some 400 feet down the west side of the pass, hoping that we would see Iron Lake, but it remained hidden behind the ridge. A nice view towards mountains on the Yosemite border opens to the west. Iron Creek rushes down to the canyon of the North Fork of the San Joaquin River. On the other side of the river is the Hemlock Crossing Trail and Foerster Peak, which I visited earlier in the season.

West side of Ashley Lake Pass. Time to go back.

Back on the east side. The green stripe north of us denotes a stream coming down from the plateau.

A ridge on the way to the Holcomb Lake valley.

A small lake on the plateau is the source of the stream that we noticed from the pass. The low ridge in the background is the last obstacle on the way to the Holcomb Lake valley.

We are ready to tackle the low ridge to the north.

 
Holcomb Lake from the ridge.
2:20 pm

Holcomb Lake from the ridge. A chute just below the ridge (left) is not the way to get down. It ends in difficult terrain. Instead, follow the ridge northeast until you can see the entire slope down to the green meadow and the stream below.

 
The route down towards the Holcomb Lake vallet.

This is the route down that we followed.

Holcomb Lake.
3:00 pm

Rest at Holcomb Lake (9471 feet; 2889 meters). The steep chute above the northwest side of the lake leads directly to Beck Lakes. It is not as steep on the other (north) side.

 
The view of Iron Mountain from Noname Lake.

Back on maintained trail. Near Noname Lake, on our way down from Holcomb Lake, we have our last clear view of Iron Mountain. There is about 1.5 miles from Holcomb to Beck's cabin.

 
Ruins of Beck's cabin.
4:40 pm

Not much is left of the old cabin, allegedly built by C. J. Beck in late 1800's. Another six(?) miles (uphill, then downhill) from here to our car at Devils Postpile.
