The Golden Gate too is about five miles in length, although at its entrance it is a little over a mile wide and widens out as you sail into the great Bay of which it is the outlet.
This is located in latitude 37 deg.

48' north and in longitude 122 deg.

24' 32" west of Greenwich, and has a depth of thirty feet on the bar while inside of its mouth it ranges from sixty to one hundred feet.

The shores are a striking feature, and on the south side range from three hundred to four hundred feet in height, while on the north the hills, in places, attain an altitude of two thousand feet; and these adamantine walls, witnesses of many a stirring event in the history of California, are clothed in green in spring-time, while in autumn they are brown, and from the distance resemble huge lions, couchant, guardians of the Gate.

But who gave it its name, and why is it so called?
These were my questions.
