16: Pop Quiz on Newport History, Origins Edition (Part 1)

This multiple-choice test covers the earliest days of Newport
Beach history.  The six questions are: 
Despite explorers and merchants sailing off the coast of
California beginning in the mid-1500s, why was there no mention of
Newport Bay in the historical record for 300 years? (The answer
will surprise you.)

Why in 1870 did Capt. Samuel S. Dunnells decide to turn into
Newport Bay and search for a "new port" despite ample warnings that
the inlet was too dangerous. (The answer is not what you would
expect.)

A tiny settlement sprung up at Newport Landing soon after its
discovery. Who were the first settlers? (This is a shocker as
well.)

What made Newport Landing unlike any port along the California
coast? (It has to do with the shallow depths of and high surf at
the bay's entrance.)

How as the cargo loaded onto ships at Newport Landing? (It was an
ingenious method in a time before cranes were common.) 

Each answer comes with plenty of context. Enjoy!
