Really do enjoy your show, I put it on one and a half speed as I am a fast listener.

A straightforward, thorough, and incredibly informative podcast delivered with a steady tenor and soothing theme music.

Glad to see you've returned. I really enjoy learning about my environment and how it got to be where it is today.

I love every episode. I'm always looking forward to the next one.

Easily the very best introductory geology podcast that I have listened to. Along with hundreds of clear and interesting discussions covering geographic time, continental drift, mountain building, erosion, mineral deposits, etc., etc., the companion website provides the transcript of each episode with maps and other great illustrations. Enjoy!

Great stuff! Dick is a master at weaving information about our Earth's beginnings into segments that are compelling and easy to understand for us lay-people. One of the best of the science podcasts yet!

Absolutely brilliant and informative podcast. Excited for the Cretaceous episode!!!

As a science junkie, I really enjoy this podcast. There is so much information given in each episode. I've especially enjoyed it since Mr. Gibson put the individual daily episodes together into monthly episodes. Once you've listened to a few of these podcasts, you'll never look at a mountain range or canyon the same.

I found this recently and am really enjoying the podcasts, especially your recent compilations. Thanks for doing this.

i'm hooked from the very start until now!

I just started listening to this podcast a few weeks ago and find the topics fascinating.

This is the best educational podcast I have ever come across. Easy to listen to, to the point and detailed enough to make it interesting.

Nov 2014…Still listening! I hate for the year to end! Feb 2014 …I subscribe to all the NH-type podcasts I can locate. I just found this one, and am really impressed with the 10 or so I have listened to. Just the right length, and just the right level of information. I recommend it totally..

A fantastic amount of information in bite-sized clips. Highly recommended. I do wonder if this goes over the heads of some, but check it out. I've learned something each episode, as a professional geologist.

I am really impressed with this podcast. The host presents clear overviews of huge topics but then can zoom in to highlight relevant details. The production and narration quality improved quickly (a bit rough the first several episodes) and the podcast is smooth and professional-sounding while still being genuine. Anyone interested in geology and paleontology will enjoy this podcast. I am a professional geologist and I learn something in every episode. Two thumbs up.

Well done, concise. I just wish all the old episodes were available on itunes. I found them on the blog, but it's easier to download from itunes.

A great daily walk through geologic time. Enjoy it.

I have enjoyed this interesting journey through time!
