Sierra granite rock meets volcanic rock at Lakes Basin & Lassen NP
Some California maps consider Mount Lassen to be the top of the Sierra Nevada range, while other maps cut it off at Lakes Basin @ Sierra Buttes, much further south. Lassen Peak is actually part of the Cascade Range of mountains that go up the coast of the Pacific Northwest. Either way, we’ve included Lassen maps in this list.
