South Ridge and West Ridge by Livingston Douglas 

Date of Climb: June 26, 2019

FULL South Ridge, Class 2

Access

From Howe, drive N on the Little Lost River Highway for 13.4 miles to an [unsigned] junction with Uncle Ike Road. This junction is 0.8 miles N of the signed junction for North Creek Road. Turn R/E onto Uncle Ike Road and drive 5.0 miles up the somewhat-rough, 2-track desert road to the Challis National Forest boundary (signed). Park shortly after this point in a grassy pullout.

If the road is too rough, you can probably make it 4.9 miles up the road and park in a pullout on the L/N side of the road only 0.1 miles before the NF boundary. The elevation at the NF boundary is about 6,180 feet. If you have an ATV, you can shorten this climb considerably by riding up the Uncle Ike Creek ATV Trail (FST-4341) for several miles.

The Climb

Hike (or drive) up FST-4341 along Uncle Ike Creek for about 3-1/2 miles to a signed road junction (7,789 feet). FST-4238 goes up a side drainage to the R/E here. Stay on FST-4341 and follow it a short distance as it drops to cross to the L/W side of Uncle Ike Creek. Jump the creek (thankfully, it is a small creek) and climb steeply N on the W side of a series of rocky cliffs. The cliffs are the toe of the South Ridge of Swanson Peak. You need to get above them and onto the ridge crest. The terrain is loose gravel and scrub. Stay close to the base of the cliffs and use occasional game trails to make progress on this difficult section.

Once you pass the final ridge tower, move R/E onto the gentle ridge crest at just below 8,000 feet. Kneel down and take in some much-needed oxygen—you probably need it. Follow the ridge crest NW up through an easy, albeit steep, pine forest. Stay just R/E of the ridge crest for the easiest going. There is some blowdown to skirt, but it’s not too bad. Once above tree line, it’s a scree slog to the top. There is a bighorn sheep trail in the gravel, but it’s weak. The summit has a huge cairn.

West Ridge (Descent), Class 2

Access

Same as for the FULL South Ridge Route. This is the first leg of a ridge traverse from Swanson Peak to Sunny Bar Peak.

The Descent

From the summit, follow the North Ridge briefly then leave it to descend the West Ridge to a minor saddle near Point 10292. Climb over Point 10292 and descend SW to the low point between Swanson Peak and Sunny Bar Peak. This is the 10,060-foot connecting saddle and the terminus of the West Ridge. The terrain on this ridge is mostly loose shale scree. Point 10292 has some ridge rock, but it’s easy to skirt or scramble over. Nothing worse than Class 2. You will even find some sheep trails to help.


Upper South Ridge, Class 2

Larry Prescott climbed the peak with his son Ben starting at Uncle Ike Creek. From the mouth of Uncle Ike Creek, it is 2.3 miles to Sunny Bar Canyon. Larry reports: “For this trip, we brought the four-wheeler and made quick work of those miles. Right before Sunny Bar Canyon, you cross the creek. We made the mistake of trying to bushwhack here through the dense growth and marshy ground. On the return trip, we learned that if we had followed the road just a bit more, we would have found a great place to cross the stream.”

He continues: “The plan was to start a traverse up the western slopes of the mountain. The ground was good and the going was easy. We reached the South Ridge (at about 9,200 feet) in about 1 hour and 15 minutes. The rest was simple–just follow this meandering ridge to the summit. Once we left tree line, the rocky ridge was solid. The scree/talus was blocky and provided good footing. What could have been a long scree slog was surprisingly pleasant.”
