Castle Rock Regional Recreation Area
1700 Castle Rock Road, Walnut Creek, United States
By the mid-1950s, Peregrine Falcons disappeared from the steep cliffs of Mount Diablo, victims of DDT. Re-introduced to the area in 1989, they have done well but now face record numbers of visitors to our wildlands, especially in spring and early summer when they urgently need space and privacy to raise their chicks. We'll view the cliffs from far below in Pine Canyon with leaders of the Mount Diablo Peregrine Team. (The Peregrine Team, a project of the Mount Diablo Interpretive Association, is an all-volunteer natural history education group.)
Our route to the cliffs follows the historic Stage Road up Mount Diablo, built in 1874. Along the way, we’ll get a whiff of a sulfur spring that a 19th century stagecoach passenger described as “smelling like the cleanings from Rip Van Winkle’s gun barrel, with some rotten eggs that came round the Horn with the 49ers mixed in.” Phew!
