It’s been a long week. Here are some of the stories you might’ve missed.

There are so many of California’s natural wonders that I still haven’t visited, and now there’s another I have to add to my list: Black Chasm Cavern in Volcano.

This 2-million-year-old cave dives 165 feet underground, and cave enthusiasts come from around the world to see it. It’s a mile long and includes five lakes and 18 different chambers, including one that hosts weddings and concerts, and inspired a scene in “The Matrix Reloaded.”

This was just one of the places featured on the California Report Magazine’s annual Hidden Gems special, which highlights off-the-beaten-path sites and spots across the state. This year, they visited a restaurant where you can kiss a dead moose, an underground labyrinth beneath Fresno, a top-notch jazz venue in Half Moon Bay that started in a guy’s living room and a museum in Chatsworth dedicated to 20th century pop culture.

A new bill making its way through the state legislature would prohibit restaurants from serving anything other than water or milk with meals marketed for children. That means no pop, no juice, no chocolate milk.

Kids could still get a sugary drink with their meal; they’d just have to ask for it. California would be the first state in the country with such a law. I never drank pop as a kid, so that might be why this doesn’t seem like that bad of an idea to me.

As the opioid crisis continues to devastate communities, some Bay Area health educators are getting more creative in their approach to saving lives. One group has started training bartenders and club and festival workers to use Narcan — the brand name for naloxone, a drug that reverses opioid overdoses.

“We, who are of the after-hours community, who live this beautiful life that’s very undersung, can actually make a difference for people,” said one San Francisco music production company executive, whose entire staff has been trained.

I had never, until this week, stopped to consider where the name “California” came from. Turns out it’s from a sixteenth century best-selling romance novel about an island, called California, protected by beautiful black woman warriors and ruled by Queen Calafia.

I know that thanks to the latest Bay Curious, which dives deep on the story behind more than 70 place names in the Bay Area. A couple of my favorites:

There’s a great interactive map where you can find the story behind your town’s name. It’s a lot of fun.

There is almost always more to story when it comes to big moments in history, and the same is true for the creation of the rainbow flag, now synonymous with gay pride.

Gilbert Baker is often credited with designing and creating the rainbow flag, but this year – the flag’s 40th anniversary – two other people are getting their due.

Lynn Segerblom and James McNamara worked with Baker to create the original rainbow flag, and Segerblom will be marching in this year’s San Francisco Pride Parade.

KQED recently unearthed this footage of a 1968 gay costume ball in San Francisco.
