"The North Arete Left Side on Hamilton Dome presents seven pitches of alpine trad climbing, blending technical finger cracks, delicate traverses, and sustained class 4 scrambling. This route challenges climbers with solid protection skills amidst one of California's iconic granite outcrops."
Rising sharply from the rugged base of Hamilton Dome, the North Arete Left Side route offers a pure alpine trad experience that challenges both the body and mind over seven engaging pitches. Your journey begins with careful negotiation of class 4-5 blocks just above the notch, summoning attention to every foothold and handjam as the rock demands precision. The route quickly reveals a large right-facing dihedral—your first defining feature. Climbing this section requires steady technique, with the crack systems ahead providing direct access to a narrow ledge.
From here, a flaring crack climbs above the ledge, leading to another crack system situated just left of a pronounced left-facing dihedral. The terrain shifts into discontinuous cracks rated 5.10, testing climbers on sustained finger locks and delicate transitions as you navigate around a substantial overhanging block. The effort pays off with a spacious ledge that serves as a welcome moment to regroup.
Continuing upward involves a nuanced traverse—up and left—into a groove before tackling a short, steep pitch over the headwall. This final technical section demands both strength and awareness, as exposure heightens and the physical effort intensifies. Beyond this, approximately 300 feet of class 4 scrambling leads to the summit, where the reward is a commanding perspective over the granite domes and alpine valleys of Sequoia & Kings Canyon National Park.
As a traditional alpine climb, the route calls for a full rack emphasizing a variety of small cams and nuts, as well as long runners to manage rope drag on traverses and ledges. With no fixed anchors or bolts, climbers must be prepared to build their own protection and anchors, reinforcing the need for solid anchor-building skills.
The approach begins with a trek through high mountain terrain, requiring focus and stamina before the rock is even reached. Expect well-marked paths mixed with off-trail moves as you ascend toward the base of Hamilton Dome. Timing your climb is crucial; aim for late spring through early fall to avoid snow and unstable conditions. Morning starts help you avoid afternoon thunderstorms common in the Sierra Nevada.
Local advice includes carrying plenty of water as alpine sources can be scarce, wearing stiff-soled shoes suitable for both hiking and technical granite, and planning for cool, variable weather by layering effectively. Given the route’s length and complexity, climbing in a well-synchronized team is essential for safety and efficiency.
The North Arete Left Side is a robust alpine climb that balances technical challenge and rewarding exposure. It suits climbers who are comfortable with multi-pitch trad climbing and alpine terrain, offering a full day in one of California’s most majestic wilderness settings.
Be prepared for loose blocks at the base notch and potential rockfall hazards during the initial scramble. Since protection relies entirely on natural gear placements, prioritize secure anchor construction. Afternoon weather can change rapidly, so avoid climbing late in the day to reduce risk of lightning storms.
Start early to avoid afternoon thunderstorms typical of the Sierra Nevada.
Carry sufficient water; alpine sources can be limited along the approach.
Wear approach shoes or boots with stiff soles suitable for both hiking and technical climbing.
Master anchor building techniques—no fixed gear means self-reliance is critical.
Standard alpine rack is essential here. Bring doubles to #3 cams and a robust set of nuts. Without bolts, expect to place all pro yourself and build solid anchors with long runners to accommodate traverses and reduce rope drag.
