Geologic Trips, Fort
Funston Fort Funston Bluff
The bluff below the Viewing Platform at
Fort Funston is made
up of sedimentary rocks that were deposited in a small sedimentary basin that
had formed along the San Andreas fault during Pleistocene time. These
sediments, called the Merced Formation, are exposed as distinct layers that
can be seen along the bluff from Lake Merced southward to the San Andreas
fault near Mussel Rock, a distance of about four miles. Some of the layers of
sedimentary rocks are nearly horizontal and some are tilted to the north,
indicating that the rocks have been uplifted and folded in the few hundred
thousand years since they were deposited. Exterior Websites Golden Gate NP Conservancy: National Park Service: _____ |
