Yosemite Park visitors are cautioned to slow down. Smoke between Crane Flat and White Wolf Lodge continues to be intermittent. It will hamper the ability of motorists to see emergency crews and vehicles on the highway. Authorities are asking motorists not to stop along the road to observe fire activity. Trails between Lukens Lake and Harden Lake remain closed due to the presence of many fire-weakened trees which could fall. Visitors to Yosemite are advised to use extreme caution.
