LOWER LAKE, Calif. — The series of “Senior Days” events at Anderson Marsh State Historic Park continue on Saturday, June 15, with a fascinating day of learning planned.

The morning program will feature Chris Watt, a geologist who has worked as an interpretive ranger with the National Park Service at the Grand Canyon and as Field Naturalist with the United States Geological Survey.

Watt will give an entertaining presentation about what he calls the "active geology" of Lake County — its volcanoes, landslides and geysers. There are a few places left for this program, so use the link below to register if you wish to attend.

In the afternoon, Greg Giusti, a local biologist who specializes in trees and forest management, will lead a discussion and “Q&A” session about the trees we see as we drive around Lake County, which trees to plant and how to take care of your trees at home.

Giusti is forests and wildland ecology advisor emeritus for the University of California Division of Natural Resources Cooperative Extension.

Giusti will present a talk with lots of time for questions and answers. There will be the chance to ask any questions you may have about trees you see in the wild, home landscaping, or garden tree care.

So, if you have questions about the trees around you, tree disease or how to deal with an unruly tree in your garden, this is the perfect opportunity to get them answered by an expert.

To register for one or both of the June 15 events, or any other future Senior Days events, visit AMIA's website.

Time will be available between the morning and afternoon sessions to bring and enjoy a picnic lunch under the big Valley Oak in the picnic area.
