Throughout the calendar year Earth’s orbit and tilt causes shifting weather patterns, movements and migrations of animals, emergence and disappearance of various plants and wildlife, and a host of other natural history phenomena.

Learn about a wide variety of these natural history topics, track the ebb and flow of the Sierra’s seasons, and catch a sneak peek at some of the wildlife to watch for in the coming year at the Tahoe Natural Year: A Journey through the Seasons talk at Sierra Nevada College on Jan. 19.

Tahoe Institute for Natural Science is sponsoring the 2017 Tahoe Nature Chase, a yearlong scavenger hunt that encourages participants to learn more about Tahoe’s environment by providing new nature observation challenges each month.

Registration is required. The program will begin at 6pm, with refreshments and no-host bar from 5:30-6pm on the campus of Sierra Nevada College.

A $5 suggested donation will be collected at the door.
