Free Talk on Sierra Nevada Hike at Sunnyvale Museum

Richard Cliff is scheduled to give a free public talk on June 8 at Sunnyvale Heritage Park Museum about retracing the route of California’s first state geological survey across the Sierra Nevada. The event is part of the Sunnyvale Historical Society’s Speaker Night series and is set for 7:15 p.m. at the museum on East Remington Drive in Sunnyvale, according to the museum’s event listing. The presentation is billed as “Walking in the Footsteps of William Brewer,” a reference to the 1860s field leader of the Whitney Survey. The museum says Cliff will use the talk to connect modern backpacking with one of California’s earliest scientific expeditions. ### Why is the talk named for William Brewer? William Henry Brewer led the original field party for the California geological survey, according to the museum’s description of the June 8 program. The listing says the California legislature created the Office of State Geologist in 1860 and named Josiah D. Whitney to lead the effort to produce an accurate geological survey of the state. Mount Whitney was later named for him, the museum notes. (heritageparkmuseum.org) The museum says Brewer, the chief botanist, assembled a team whose work produced a large body of information about California, including the first description of Kings Canyon. Brewer also kept journals during the expedition, later published as *Up and Down California in 1860-1864*, according to the event page.

Richard Cliff will describe how he and hiking partner Elvis Fu set out to better understand the early California surveyors by following their routes through the Sierra Nevada, the museum says. The event page frames the presentation as a “visual journey” through the mountains and says Cliff will compare the original explorers’ hardships and motivations with those of modern hikers. (heritageparkmuseum.org) The museum’s description says Cliff grew up hiking in England’s Yorkshire Dales and Lake District before moving to the Bay Area in 1990 for a technology career with Altera Corporation. It says he later continued hiking with his wife and family and, 12 years ago, began backpacking across the Sierra Nevada with Fu in search of new routes and historical connections.

Sunnyvale Heritage Park Museum says its mission is to preserve and share the city’s heritage through education, promotion and preservation. The museum describes its collections and exhibitions as a way to spark curiosity about local and regional history for Sunnyvale residents and neighboring communities. (heritageparkmuseum.org) The June 8 program fits that mission by tying California state history to a public lecture format the museum regularly uses. The museum’s website says Speaker Night is part of its public programming, and recent events have included a February 2026 presentation by Pong creator Al Alcorn. ### What will people hear if they attend? The June 8 listing says Cliff will take the audience “back in time to the early 1860s” and follow the Whitney Survey team across California. (heritageparkmuseum.org) The museum says the presentation will ask who those men were, how they compare with modern hikers and what drove them to endure severe hardship while documenting the state’s geology. Cliff is now retired and documents backpacking trips on a YouTube channel, according to the museum. That detail suggests the talk is likely to include photographs, route comparisons and first-hand hiking material alongside the historical account, though the museum’s published description does not provide a formal agenda. (heritageparkmuseum.org) ### When and where is the event? The museum lists the event for June 8, 2026, at 7:15 p.m. at Sunnyvale Heritage Park Museum, 570 E. Remington Drive, Sunnyvale. The museum website says admission is free. June 8 will also include the museum’s annual membership meeting at 7 p.m., immediately before the Speaker Night, according to the museum homepage.
