General Conditions

The trail up to Hidden Valley as well as the climber's route towards Cascade Gulch were both impacted by the monsoon event that occurred on Shasta on 8/2/22. Mudflows were visible in the flats of Hidden Valley as well as in the center of Cascade Gulch proper. The Hidden Valley trail is still navigable and is a good option for day hike from Bunny Flat. 

Be cautious of loose rock if heading up to Cascade Gulch, Lake Sisson or Shastina. There is little-to-no snow along the way which leads to tedious route-finding and ascent/descent options. Clarence King Lake is currently looking pretty dry but Lake Sisson is beautiful! The Whitney Glacier is rocky and broken. Rock and ice fall were audible while on Shastina. Routes up the Whitney are out-of-condition and very much not recommended right now. If choosing to head up from Hidden Valley, make sure you have the ten essentials as well as extra food, water, and other supplies. This area of the mountain is remote and not frequented by many people these days; it is only recommended for experienced hikers and climbers.
