“The Trails of Mount Diablo: A Historical Perspective”

Thursday, March 14 (not our customary Wednesday), 7 pm, Ygnacio Valley Library, 2661 Oak Grove Road, Walnut Creek.

At the next general meeting of the Mount Diablo Group, Frank Valle-Riestra will guide us on an intimate visual exploration of the trails of Mount Diablo. Some of the trails we shall see are popular and well-known, others less so, but all take the hiker into the heart of a remarkable wilderness, so close to our back yards.

Frank’s slide presentation will focus on the beauty of the trails themselves and their environment, and will emphasize trail-oriented historical events of the past 50 years–new trails, trail improvements, trailside celebrations, changes in natural features, and the origin of trail names. You may recognize some of the familiar features–and you will be inspired (or reinspired) to discover for yourself the hidden treasures of this unique landscape.

Frank Valle-Riestra has been intimately associated with Mount Diablo for over half a century. Frank’s numerous articles on the natural and cultural history of the mountain, as well as his maps, photographs, and trail descriptions, have introduced thousands to the mountain’s wonders. A retired chemical engineer, Frank is a founding member of the Mount Diablo Interpretive Association. Frank and his wife Edith are long-time residents of Walnut Creek.

Everyone is welcome; no reservations are necessary. If you have questions, contact Ken Lavin at or (925)852-8778.
