Significant precipitation fell on the upper mountain the last week, most of that was in the form of snow and hail. There is significant snow and ice on the O-S and descent from the summit of the GT. Crampons or spikes are recommended for a safe ascent/descent. You can avoid most of the snow and ice below the upper saddle.

With the recent high pressure and warm temps, the Owen-Spalding route has dried up substantially. Any snow or ice that remains on the route can easily be bypassed. We are no longer recommending ice axe and crampons to the general public. Keep an eye on weather forecasts and plan to be down before afternoon thunderstorms.

Crampons and an ice axe remain necessary equipment for a safe ascent and descent of the Owen Spalding route. Snow and ice on the ledges and chimneys of the upper mountain cannot be avoided.

Ice and snow on the upper mountain will make for mixed climbing conditions on the OS. Crampons and an ice axe, possibly 2 axes, will be necessary for an ascent.

From the Lower Saddle to the summit, expect to encounter winter climbing conditions, including ice, snow, and verglas. The chimneys of the OS are in great mixed climbing conditions. Crampons and ice axe are necessary tools for safe travel up the Grand Teton as of today.
