Tyndall Col
Peak · 13,031 ft · Eastern Sierra corridor
Tyndall Col, a 13,031-foot pass in the Eastern Sierra, sits on the divide between the Kern River and Inyo drainages. High, exposed, and wind-prone, it draws climbers and backcountry skiers chasing alpine access.
Wind accelerates through the col; sheltered terrain is rare. Morning hours deliver the calmest conditions; afternoon gusts climb sharply. Temperature swings from subzero in winter to near freezing in spring. Exposure is absolute; weather changes fast.
Over the past 30 days, Tyndall Col averaged a NoGo Score of 36.0 with an average wind of 12 mph and temperatures near 16 degrees Fahrenheit. Maximum wind gusts have reached 43 mph. The week ahead tracks similar patterns: expect calm mornings, strong afternoon wind, and avalanche hazard lingering through spring snowpack transition.

About Tyndall Col
Tyndall Col sits at 13,031 feet on the Sierra crest, bridging the Kern River drainage to the west and the Inyo drainage to the east. The col is accessed primarily from the Shepherd Pass Trail or from the Inyo-Kern corridor via Tyndall Creek. Driving time from Lone Pine (US Highway 395) runs roughly 90 minutes to the trailhead; from Independence, the approach is slightly shorter. The col itself is a natural saddle in the ridge; no maintained infrastructure exists. This is a technical mountaineering destination, not a casual day hike.
Spring at Tyndall Col means winter snowpack still dominates; the 30-day average temperature hovers around 16 degrees Fahrenheit, with minimum readings dropping to near freezing or below at night. Wind is the defining hazard. The 30-day average wind speed is 12 mph, but maximum gusts have reached 43 mph; afternoon channeling through the col is systematic and severe. Early morning alpinists depart before dawn to clear the pass before wind velocity peaks. Late September and early October offer the most stable conditions: lower wind, negative avalanche cycle progression, and clearest views. Summer is possible but rare for climbers seeking primarily this col; most route through en passage.
Tyndall Col suits climbers tackling Mount Tyndall or the Kern-Kaweah crest traverse. Backcountry skiers use it to descend the north side into the Shepherd Creek drainage. The typical user is experienced in alpine scrambling, snow navigation, and self-rescue. Parking at the Shepherd Pass trailhead fills mid-morning on weekends and does not have a shuttle system; arrive before sunrise or plan a weekday trip. Avalanche terrain is continuous and serious: cornices form on the east face, wind slabs build on leeward slopes, and the snowpack transition in spring creates instability. Consult ESAC forecasts before any approach involving snow.
Tyndall Col connects a larger alpine network. Mount Tyndall itself is 2 to 3 hours from the col and offers views east to the White Mountains. The Kern-Kaweah crest runs south, linking Kern Point and other 13,000-foot summits. Shepherd Pass, immediately north, provides an alternate high-altitude crossing with similar wind and cold exposure. For lower-elevation Eastern Sierra access, Tuttle Meadow and the Tungsten Pass area offer gentler terrain and stronger afternoon thermal activity. The col is best suited for skilled, self-sufficient parties; turn back if conditions deteriorate or avalanche hazard increases.
