South Sister & Moraine Lake

After a great hike along Tam McArthur Rim it was finally time to tackle the South Sister. At 10,358′ the South Sister is the third highest peak in Oregon behind only Mt. Hood (11,235′) & Mt. Jefferson (10,497′) and the only one of the three that doesn’t require technical climbing skills. We had tried to do this hike a couple of times in 2012, but the Pole Creek fire in the Three Sisters Wilderness kept us from being able to do it. We had been looking forward to this hike all year and most of our earlier hikes were chosen in part to help us prepare for the demands of the climb.

We knew this was a popular weekend for a popular hike so we expected a large crowd would be joining us so we got to the trial head at Devils Lake early and were ready to go just as the Sun began to rise.

There was just enough light for us to not need to use our headlamps as we set off across Tyee Creek and the Cascade Lakes highway and entered the Three Sisters Wilderness.

The first mile and a half of the trail climbs through the forest in a narrow valley before cresting on a large plateau. Brief views behind us revealed Diamond Peak, Mt. Bachelor and distant Mt. Thielsen but it wasn’t until we reached the plateau that we could see our target, the South Sister.

Travelling along the plateau was an easy walk with gentle rolling hills and mountains on three sides. The South Sister loomed ahead while Mt. Bachelor sat behind and Broken Top welcomed the rising Sun to our right.

After nearly 3/4 of a mile we spotted Moraine Lake in a sandy bowl below us to the right. A trail joined here and we decided that we would head down there on the way back if we felt up to it. To our left a large lava flow covered a portion of the plateau.

The first 1.8 miles along the plateau had only gained 500′ of elevation putting us at 7200′ when the trail began to climb with a purpose. We were 2.2 miles from the summit and still over 3000′ below it. Not only did that mean a steep trail but the trail consisted of sand and loose rocks making footing challenging. To add to the challenge was the clear view to the top reminding us of just how much further we had to go :).

The first section of steep climbing was amid larger gray rocks. There seemed to be an endless number of possible routes braided among these rocks, but sticks and rock cairns marked the correct path. A ridge blocked the view to the east, but to the south the Cascade range was unfolding and lakes dotted the forest. To the west the Willamette Forest stretched beyond the lava mesa.

The first section ended atop a sandy saddle at the base of the Lewis Glacier. Below the saddle was Lewis Tarn, a pretty glacier melt lake. I had arrived at the saddle before Heather so I headed down to the lake to get a couple of pictures and feel the water (yes it was cold).

Broken Top was now visible to the east as we sat at the saddle to take a break and get some food before the final ascent.

The rock composition changed here and now we were traveling along a red cinder ridge between the Lewis & Clark Glaciers. The Lewis Glacier had some interesting crevasses.

The trail was just a little steep here, but the footing was better making this section a little easier than below the saddle. The views were also even more spectacular as we were now looking down across the Lewis Glacier all the way to the peaks surrounding Crater Lake to the south.

Upon reaching the lop of South Sister’s rim a vast snowfield filled the crater on top of the mountain.

Across the snowfield was the high point and actual summit of the South Sister. Even though it wasn’t a perfectly clear day, where a view of Mt. Shasta would have been possible, we could see all the way to the tip of Mt. McLoughlin in southern Oregon. In addition to the over half dozen mountain peaks to the south many lakes were clearly visible dotting the forest.
181
The trail continued around the rim to the right on it’s way to the summit. Along the way views to the east improved revealing the Green Lakes below the Prouty Glacier between Broken Top and the South Sister, Paulina Peak to the SE, and Tam McArthur Rim where we had hiked the day before. The best views still lay ahead though.

As we continued around the rim we toward the north side of the mountain the most dramatic views began to unfold. Lined up was a parade of Cascade peaks, the Middle & North Sister, Three Fingered Jack, Mt. Jefferson, Mt. Rainier, Mt. Hood, and Mt. Adams. Mt. Rainier and Mt. Adams were only barely visible even with binoculars due to haze but they were there like ghosts on the horizon. Below the South Sister lay the Chambers Lakes in a multitude of colors, from brown Carver Lake to blue Camp Lake like an artists palette.

We’d finally reached the summit!

We decided to try and continue around on the rim loop after noticing what appeared to be a well worn path. Mt. Washington was hiding behind the Middle Sister and I thought we might be able to find the missing mountain from the western edge of the rim. The path turned out to be much less of a trail and more of a scramble as we climbed over rock piles along the edge of the mountain. A strong wind was blowing across the snowfield making us feel like we could be blown right off the edge. We did manage to get a glimpse of Mt. Washington’s spire over the shoulder of the Middle Sister and got views of of the Lost Creek and Eugene Glaciers as well as several creeks and lakes below the Husband, but I don’t know that I would take that portion of trail again.

After a short stint on the snowfield below we managed to complete the rim loop and arrived back at the climber trail which had become much more crowded. A line of hikers could be seen making their way up as some of the early hikers were making their way back down.

Surprisingly the descent was much easier than we had anticipated. Despite the numbers heading up there was plenty of room on the braided paths and the deep loose sand helped keep the descent under control. The views were just as impressive going this direction. In fact Broken Top looked even better now that the Sun had risen over head bringing out the colors of the old volcano. On the way down we got a little separated. Heather ended up falling in with two young ladies that shared a similar pace. They quickly formed a trail bond looking out for each other. In her shyness, Heather failed to introduce herself or get their names, but she was very thankful for their company and the feeling of camaraderie. It was nice for her to enjoy the company of women on the trail for a change, even if it was only for a short time.

When we reached the junction for the trail down to Moraine Lake we decided to head down. I blame the lack of oxygen for that decision. Actually the lake was lovely and only added about 3/4 of a mile and 500′ of additional elevation gain. We sat at the edge of the lake across from the South Sister and had another snack. I think we both would have been happy to stay there, but we would have gotten a little cold that night.

We pulled ourselves away from the peaceful lake shore and returned to the climber trail via a trail that had come to the lake from Green Lakes and continued on to Wickiup Plain. The intersection was very close to where the climbers trail first crested the plateau so we were quickly back in the forest heading down the final 1.5 miles back to the trail head. Now that it was light we could see this portion of the trail much better. A nice creek ran beside the lower portion of the trail and we spotted some aster blooming in a meadow along side it. After crossing the highway we reached the bridge over Tyee Creek which was lovely.

Then we were back at the large parking area where we had started. It had been a beautiful day, and we really couldn’t have asked for any more out of this hike. We got one last look at the South Sister before loading up the car and heading back into Bend.
