Don’t worry if you see smoke coming from Glen Ellen. A 15-acre prescribed burn will occur at Jack London State Historic Park from 8 AM to 8 PM today. A few trails near the burn area, including Old Fallen Bridge Trail, Upper Fallen Bridge Trail and Mountain Fire Road may be temporarily closed during the burn. Of course, if the weather is not ideal, it will be rescheduled. Cal Fire is leading the burn along with cooperation from Sonoma Valley, Schell-Vista and Kenwood Fire, the Sonoma Valley Wildlands Collaborative and Jack London Park Partners.
