Annie Lydia Rose (1883 – 1972) was a gold prospector and mining entrepreneur active between 1910 and 1972 in Bear Canyon and adjoining Pine Canyon in the north-west corner of the Angeles National Forest. She was uncharacteristically bold beyond her age, gender, and the restraints of the late Victorian era in which she grew up. During her life and now through her legacy, she is considered an authority on the legendary Lost Horse Mine also referred to as the Lost Padre Mine.
