Obsidian: Not just a valuable Minecraft resource (Yellowstone Monthly Update — November 2024)

No way

There is a cave just north of Columbus, OH, in Delaware County that has a black obsidian spear point. I think that they thought that it might have come from there, or near there.

Always one of the better days in my month, thanks!

Also used in european stone age cutures

As a long-time Minecrafter, I approve this message. :-)

Greetings from south Texas! I'm a retired geophysicist and always much more enjoyed listening to the geologists. All the best!

as someone who has played minecraft for 12 years, you are absolutely right! also its nice to see an agency like you acknowledge that minecraft exists. makes me wonder if any usgs employees plays minecraft

Thank you !!!

You should do a series in minecraft where you discuss all the different rocks in the game.

I always love the beginning of the month, for Mike's update of the previous month!

Does anyone at USGS remember David Hastings from Boulder?

I appreciate the little nuggets that are included with the monthly updates. Thanks.

Does the new infrasound instrument pick up anything from Steamboat minor eruptions?

Yay, 1st of the month and a new and very informative video. Thanks!!!

There is still a little bit of time to go to Yellowstone before the roads are closed and snowmobile and snowcoach tours begin. The park is covered with a light coating of snow already and it is really beautiful. Go and see it now or wait until mid-December and take one of the tours. They are well worth the cost.

I found an arrowhead of obsidian in Ohio.

Thank you, Mike.

Thanks Mike! We love your monthly updates on Yellowstone and the interesting tidbits thrown in!

Mining a volcano is never a good idea.

What causes pitchstone to become more filled with H2O and end up so different from obsidian? I live next to a huge amount of volcanic pitchstone but very little of any of it could be used for blades

Craters of the Moon has obsidian also. East Camas creek has a large quantity, Close to Yellowstone.

can you guys update shakemap of 7.8 earthquake in turkey?
its been over 1.5 years and it still didnt get updated

I never expected a Minecraft / Mike Poland crossover, but I'm here for it!

10000years ago it was the founding of flowering industry. The wealth of Lipary for instance.
