Keyhole Route Conditions
The warm weather over the past month has melted the snow on the Keyhole Route. The route is now snow free and can be climbed completely on rock. Due to changing temperatures from night to day, visitors may encounter icy sections on the Narrows and Ledges during the early morning hours and wet sections of rock in the afternoon. Climbers should also be aware of slippery, polished rock throughout the route. The difficulty and hazards involved in climbing the Keyhole route vary depending on current weather and time of day. Be prepared to turn around when conditions exceed your abilities.
The trail to Chasm Lake is now snow free. The rock slabs leading up to Chasm Lake are wet and polished in spots. Please use caution on this slippery terrain.
