Navigation and field downloads unavailable

P10-C safety gate: the mapped GPX still has one unresolved approximately 3.6 km sparse segment, so continuous-route navigation, GPX download and offline use are disabled. The page stays available as a mapped route reference; field navigation returns only after a rendered comparison with a defensible source and any required repair.

Source: TerraClimate 1991–2020 monthly averages. Averages for the area at each point’s elevation (4 km grid, corrected for height). Not a forecast or a report of current trail conditions. Snow at the high point is estimated with a simple snowpack model from these temperatures and precipitation, not observed; steep islands and high summits can hold more snow than it shows. Daylight is for the 15th of each month. Hut, transport and park seasons are separate: check them for your dates.

Averages cannot establish current trail conditions. Check recent local reports, the forecast and restrictions before departure. Snow and ice can persist on shaded sections or arrive outside the usual season.
