The Three Arch Rocks National Wildlife Refuge, established by President Theodore Roosevelt (born on October 27, 1858), recorded hunters killing dozens of sea lions at a time for skin and oil, and sportsmen shooting seabirds purely for sport.
The refuge was established by President Theodore Roosevelt after being persuaded by two young conservationists  William L. Finley and Herman Bohlman  who studied and photographed Three Arch Rocks from Oceanside beginning in 1901. They recorded hunters killing dozens of sea lions at a time for skin and oil, and sportsmen shooting seabirds purely for sport.
