hi Jeff: THAT IS ONE ROUGH ISLAND, HIGH MTS ETC. alive with snakes, and the Series haven't eaten anyone lately according to Gov't / and my personal knowledge. I have many friends among the Seris. The jefe (chief) is a woman about twice my size heheh. An Army garrison is on the island mostly to keep visitors away since it is a protected island, national heritage site, No permit, no landing.
As far as the sea treasures go, the island is surrounded by the most violent and vicious currents imaginable Diving can be done, but it is very risky in certain areas. The area between the island and the mainland is called "Sal si puedes" get out if you can" . It is loaded with sailing ship wrecks that learned this the hard way. The entire gulf waters surge though the narrow opening with the daily tidal change. It creates enormous whirpools, currents etc. Why the LORD invented Helicopters snicker.
San Estaban is also out of bounds.
Mexico owns the entire gulf of California or Sea of Cortez.
I know of a fantastic Gold placer there, but nothing can be done right now.

p.s. The Tiger sharks reach white shark size and eat anythng livng or dead. . Also the giant squid there will attack, some run to over 6 ft. Good eating if you win.
