Lost Arrow Spire
Peak · 6,700 ft · Yosemite corridor
Lost Arrow Spire is a 6700 ft granite peak in Yosemite's high-Sierra corridor, rising above the Yosemite Valley rim. Winter and spring approach demands avalanche awareness and stable snowpack assessment.
Wind funnels through the Yosemite corridor on afternoon thermals, especially when Valley floor heats. Temperatures average 35 degrees Fahrenheit over the last 30 days. Morning calm windows close by mid-day. Crowding stays light year-round; the real constraint is snow and exposure.
Over the past 30 days, the average NoGo Score has held at 33 with temperatures averaging 35 degrees Fahrenheit and wind at 7 mph. The week ahead will show typical spring variability in wind and temperature; watch for afternoon wind gusts and lingering snow patches in north-facing gullies. Crowding remains sparse relative to iconic Valley destinations.

About Lost Arrow Spire
Lost Arrow Spire sits on the north rim of Yosemite Valley at 6700 feet, accessed primarily from Highway 120 via Tioga Road or from the Valley floor via Valley-side trails. The peak lies in avalanche terrain managed by the Sierra Avalanche Center. Approach routes cross seasonal snow fields and require navigation experience; do not assume summer-only access windows. The location is best reached as part of a high-Sierra circuit or as a scramble from Yosemite Point rather than a standalone destination.
Spring and early summer are the prime windows, when snowpack stabilizes and day length permits full-light approaches. The 30-day average temperature of 35 degrees Fahrenheit reflects the current shoulder season; expect 21 to 51 degrees Fahrenheit across the full calendar year. Wind averages 7 mph over 30 days but gusts to 22 mph on storm days, creating rapid visibility and stability shifts. Crowding averages 3 out of 10 even at peak season, making this a genuine solitude destination. Fall brings clearer skies and more stable snow; winter requires avalanche terrain experience and current conditions briefing.
This location suits experienced mountaineers and scramblists comfortable with scrambling on exposed granite and assessing snowpack. The typical user comes from the Tuolumne Meadows or Tioga Road corridor and is already acclimated to high elevation. Plan around afternoon wind, which builds predictably as Valley thermals rise. Parking at Tioga Road trailheads fills on calm weekends; arrive early or hike weekday mornings. Bring sun protection and a wind layer; afternoon conditions deteriorate rapidly in spring.
Nearby peaks including Cathedral Range and Clouds Rest offer similar elevation and solitude with slightly different access angles. Cathedral Peak is more popular and less avalanche-exposed. The Yosemite corridor as a whole sees low crowding relative to Valley floor attractions; Lost Arrow Spire sits at the remote end of that spectrum. Compare approach conditions with Tuolumne Meadows weather before committing, as the two sites sit only a few thousand feet apart horizontally but respond differently to wind and storm systems.
