California Mountain: Lassen Peak 

Did you know that as early as 1836 the mountain was mapped as Roger's Peak? In 1851, Scholfield's map called it Mt. St. Joseph, and in 1855 and 1857 maps designated the formation as Lassen's Butte. By 1879, Peterman's map called the mountain, Mount Lassen. The "official" name is Lassen Peak as of 1915.~
