Mt. Ritter is the tallest point in the Ritter Range, a subsidiary range of
the Sierra crest. It located in the Ansel Adams Wilderness (Inyo
NF), about 12 miles northwest of the town of Mammoth
Lakes, California. Most people do not day-hike Ritter, so
an overnight stay is standard. However, like all wilderness areas,
overnight stays in the Ansel Adams Wilderness require a permit from the
forest service. Because this area is very popular with hikers, there
are two things to know. First, there is a quota period in effect
from the last weekend in June through September 15. You may reserve
permits in advance based on availability through the local forest service
ranger station (click
here). Second, there is a shuttle bus to the trailhead that
operates between the hours of 7:30am and 5:30pm during the summer months;
passenger car travel to the trailhead (over Minaret Summit) is prohibited
during these hours. As a result, you must either take the bus to the
trailhead at Agnew Meadows or drive outside the bus operating hours (click
For identification of the major landmarks on the mountain, please consult Alan
Ritter's fine overview on climber.org (available here),
as I use the same geographic references here.
Borrowing from Alan's trip reports, our intention was to climb Mt. Ritter via
the lower gully, SE Glacier and Owen's Chute. While we stuck to the route
most of the way, we had a couple of deviations. First, we climbed all the
way up the lower snow gully (way past the "tree rock") and found
ourselves angling up above the SE corner pinnacle (this put us on what
Secor calls the "Clyde Variation"). Second, we misjudged the top
of the lower gully and missed the "landmark dome" on the descent,
which put us about 1/2 mile to the south near Ritter Pass. Click on the
photo below to see the path of our ascent and
Step by Step:
Set forth below is a description of each part of our climb with a photo

detailed photo, our route is shown in red. You can also reference an
annotated USGS topo map of the route.
Gully: We started the climb by hiking to the bottom of the lower
gully. After crossing the creek, we ascended the gully. As
mentioned earlier, the gully is fairly steep, and unless you are
scrambling up the rocks (which is difficult this early in the year, due to
snow), crampons and ice axes are highly recommended.

the Gully: We stayed in the gully almost all the way to the top,
where it sort of terminates into a large bowl. From here, we
scrambled up a short class 3 pitch, and then descended very slightly to
the bottom of this talus slope. The climb was easy class 2 up this
slope to the bottom of the horizontal snow ridge at the top. The
snow ridge is steep (about 45 degrees), but levels out very quickly to a
horizontal band of rocks (just visible at the top of the snow ridge) that
separates the snow ridge from a large suncupped snow bowl. The snowy
chute on the left is where we later descended. We got carried away
with our glissade, however, and ended up missing the lower gully and had
to descend to the south of the landmark dome.
The Upper SE Snowbowl: After getting to the top of the snow
ridge and crossing the rocky band, we traversed across what I'll call the
"Upper SE Snowbowl" and then angled up and to the left to get to
what I'll call the "SE col" -- the narrow gap between this
snowbowl and the SE Glacier proper. (The Upper SE Snowbowl is marked
on the USGS 7.5 minute as "Per
Snow"). The suncups here were absolutely friggin' huge and were
really a pain in the behind to cross, but the view from up here is
The SE Col: After battling the
suncups, we angled upslope to the
SE col. Once there, there is about a 150 foot gap between the Upper
SE Snowbowl and the SE Glacier itself. The gap is visible in the
foreground of this photo. I am standing on the edge of the SE
glacier, having just contoured around the gap. This is the
sketchiest part of this route, as it involves a traverse across this steep
slope over rotten snow with nice sharp pointy rocks below. Of
course, a safer option would be to descend slightly to the rocks, then
climb back up the other side of the gap to the edge of the glacier.
I was too lazy to lose any vertical at this point of the climb, so I did
the traverse, using my ice axe to self belay. Above my head, you can
see Secor's chute.
The Chutes: As mentioned earlier, I followed Alan Ritter's lead
and ascended Owen's Chute to the summit snowfield (the red line in this
photo). From there, the climb is a pretty straightforward talus
slog/snow climb (depending on conditions) to the top. Looking from
earlier parts of the climb, there did not appear to be much snow on the
summit approach, so I left my crampons at the bottom of Owen's Chute (the
chute was bone dry). However, once I got up there, there was no way
to avoid the snowfield by climbing around it, so I did an uncomfortable
crampon-less traverse of the snowfield at its upper reaches to get to the
summit ridge. Fortunately, it was late enough and the snow soft
enough to allow me to kick in some good steps.
1. Ritter in
One Day. Doing Mt.
Ritter in one day from Agnew Meadows is quite arduous, even if you are spending
the night after the climb at Ediza Lake. Though it is completely
attainable (some hardy souls have even day-hiked
Ritter), I think the climb is more enjoyable if you camp at Ediza the night
before and get an early start. This beats the heat, and the mosquitos.
Besides, Ediza is one of the more beautiful spots in the Sierra, so it is better
to be here than the Shilo Inn.
Variation. Although we did it by accident, I like the Clyde Variation
route above the SE Corner Pinnacle. I think it is a more direct and
gradual route than contouring below the pinnacle (which requires climbing
straight up the SE Glacier, rather than angling up across it). However,
the gap at the SE col is a little sketchy if you are
not comfortable traveling on snow, and Alan Ritter advises me that in some years
there is a nasty cravasse that extends down and may need to be bridged in order
to gain access to the SE Glacier. Snow conditions this year did not
present this problem.
3. Don't Miss
the Lower Gully on the Way Down. I know it sounds stupid, but it is
easy to miss the lower gully if you are coming down from the SE col.
Griffin and I totally missed it, and Liz and EB (descending separately) nearly
missed it and had to backtrack a little bit to get into it. I think the
problem is that the landmark dome is tough to see from that high up, plus there
is a slight ascent required to get to the top of the gully from the bottom of
the talus slope. Add this to the fact that you
are trying to get down quickly and there is a very enticing glissade
chute to the side of the talus slope that quickly shoots you past the
entrance to the lower gully.
