DesertSAN DIEGO–San Diego Natural History Museum will present author Mark Jorgensen who will discuss his five decades of experience studying the desert bighorn sheep, through the beautiful images taken by photographer Jeff Young.

Desert bighorn sheep are found in seven western states in the U.S. and six states in northern Mexico. The recent publication of the beautifully illustrated coffee-table volume, Desert Bighorn Sheep: Wilderness Icon, informs readers of the successes of wildlife management efforts to restore the wild populations of desert bighorn in the U.S. and Mexico.

A book signing will follow the lecture. Books are available for purchase in the Museum store.

The 7 p.m. event will be held at the San Diego Natural History Museum on December 16.

Tickets are $9 for members and $12 for non-members. Purchase tickets online, at the Museum’s Admissions Desk, or by phone at (877) 946-7797.
