In October 2017, fires in Napa and Sonoma counties spread rapidly, impacting Mount St. Helena and the surrounding Robert Louis Stevenson State Park. Local groups are actively working to assess damage to the crags – initial assessments appeared to show that the rock was damaged far worse than the bolts, with The Bear being the crag most affected.
Bear, The – Use extreme caution
The Bear Cliff was most deeply affected by the fires.
Rock: The heat caused a lot of surface spalling and loosened many features that were already hollow. However, the underlying hard quartz rock, is generally solid and will be safe to continue to climb on. Local groups have been working to remove any lose rock that might come off and hurt somebody. Small flakes and chips will continue to come off.
Bolts: In general, it does not appear that the fire weakened or damaged the bolts themselves, though on occasion the rock around the bolts was found to be compromised. However, many of the 3/8″ Rawl 5-piece bolts were due for replacement before the fires.
Clean up work: The priorities have been to replace the 3/8″ Rawl 5-piece bolts that need replacing and to clean up as much loose rock as possible.

Trails are reported to be in good shape and stable, but caution is still advised following periods of rain.
