Best overview ever. We are travelling to DV next month it this is way better than any of the commercially produced TV programs (e.g. How the Earth Was Made) as far as actual technical content and understanding. Thanks Andrew!

I have no formal training about geology but spend lots of time in DV. Started 40 years ago at a time when I had no idea what I did not know but like Andrew just knew I liked what I was seeing. I’ll admit I picked up maybe 60% of what Andrew was saying but that amount was so enlightening. Thank you for the effort in putting your presentation. This format reminds me of when I was younger and I participated in Toastmasters.

You want to start about 10min in.

Great lecture
