The mountains of California, including the Sierra Nevada and the Coast Ranges, are geologically diverse and have varying ages. The Sierra Nevada, for instance, began forming around 100 million years ago during the Mesozoic era, while some of the coastal ranges are older, dating back over 200 million years. Overall, the complex geological processes that shaped California's mountains continue to evolve today.
There are several mountains that follow the California coastline. These mountains are the Sierra Nevada, the Cascades, and the Klamath Mountains.

A fault-block mountain can be found in Death Valley, California and also in the Sierra Nevada mountains in California. Movement of large crustal blocks form fault-block mountains.

sequoia the oldest tree is the Bristlecone Pine (Pinus longaeva) found in the White Mountains in California.

Most mountains are old.
It's hard to say. The tallest are the youngest because they have not eroded down yet, but this not make short mountains old either. There were mountains in flat places millions or even billions of years ago.
