Rated 5 out of 5 by from Dr. Wysesslon's Enthusiasm Is Infectious Bravo! I thoroughly enjoyed this course! Of course, it's a survey course so it's short on detail, but the professor opened my eyes to a new way of seeing these wonders, many of which I have actually visited. Hint: If you find his speech a bit slow at times, increasing the speed in the Settings works wonders! He doesn't sound rushed; he sounds the way he looks -- extremely excited!

Rated 5 out of 5 by from Thank You Prof. Wysession, Spectacular Lectures !! This lecture series, The World's Greatest Geological Wonders, ought to be a mandatory course for everyone, what a great way to learn about the earth's natural wonders, in quick, bite size 30 minute chunks. Prof Wysession can make any subject interesting as he shares amazing photos, details, and data. He makes this series so enjoyable many people interested in travel, history or geology may very well want to watch the whole thing twice, my wife and I certainly will. This course is highly appropriate for almost any age group, from 9 to 90. I truly hope prof Wysession produces more such video lectures (be sure to do the videos, don't miss out on all the photos and charts). What a gift to curious minds!! Watch this video series and then go see some of Earth's amazing features for yourself. We are !!

Rated 5 out of 5 by from Astounding The course comes across as a cruise ship lecture: enjoyable, focused insight by a highly polished lecturer. It is better organized than his other TGC course "How the Earth Works," as his limited mineralogy is now site specific and better helps you recognize minerals in the field. Mineral geochemistry is better understood in TGC's "The Origin & Evolution of Earth" (Hazen) or "Nature of Earth" (Renton). Wysessions' animations and demonstrations are marvelously timed and their content is spot on. His frequent use of plate tectonic animations keep the listener oriented to time and geo-position. It is why this "Wonders" course is markedly superior to Ford Cochran's aimless "Wonders of the National Parks". Having had to use paper maps of tectonic eras in the field over the years, I really appreciate such powerful teaching aids. CLIMATE CHANGE: I will use his Climate Change theme as example of balanced, thorough teaching. Though climate has changed throughout history and thus "climate change" would seem to be a nonsense descriptor, some believe we may one day be able to "control" climate via (among other theories, L26) spraying sulphuric acid high in the atmosphere to "stabilize" climate change (at 1/100th the cost of reducing CO2). While still "pie in the sky", this POV suggests that climate change could become climate stability. Yet it's not that simple. He reminds us of the disastrous 1815 Tambora eruption whose 1816 "year without a summer" brought horrendous starvation and the French Revolution. Adding sulphuric acid cooling to eruption cooling (many eruptions are long overdue) might prove disastrous. He also acknowledges that without the modern production of CO2, we would now be in an Ice Age due to "variations in the eccentricity of Earth's orbit, combined with the tilt & procession of its axis" (L14 & courses above). Additionally, Sun output variations have caused significant temperature divergences such as the Medieval Warm Period, the Little Ice Age, and contribute to today's warming (L28). Wysessions laments the eventual demise of oil/coal resources within 100 years, as a return to low global temperatures would be disastrous (L15). Why? Because cooling periods last millions, not hundreds, of years. The bottom line seems to be that without theoretical tools like sulphuric acid seeding, the only thing we presently control is CO2. Since 20,000 years ago sea level has risen 400 feet (L15) and continues to rise 3 mm a year (L9). If the ENTIRE world's ice melts, the sea could rise another 230 feet (L17). Limiting CO2 is necessary given the huge populations immediately at risk in the Ganges delta (L9) & the Maldives (L28), etc EXAMPLE: In (L20) he points out that Tidewater Glaciers' behavior is NOT a direct response to climate change. I remember an Alaskan Park Ranger's distress when I asked why a particular tidewater glacier, according to her photographs, had massively receded 200 years ago & not really changed since. Alarmed, she chanted: "Global warming! Global warming!" - as if that incantation would negate the photographs. The episode is why TGC is a valued resource. PROs: The Guidebook is excellent, requiring minimal note taking. His "4 similar sites" finishing out each lecture were always interesting. His L6 Cambrian explosion cautions were interesting. For myself, his discussion of terra rosa (L12) explained iron oxide deposition in a quarry where it was not expected. His explanation of polygonal contraction for salt flats, honeybee wax, and Devil's Tower phonolite (L18) was, for myself, an unexpected wonder of energy conservation. Loved the L29 peanut butter Dead Sea demo. SUMMARY: If you are serious about mineralogy, perhaps start with Hazen's (more complete) or Renton's (old school, deductive but easier) geo courses. Regardless, don't miss this course.

Rated 5 out of 5 by from Wonderful exploration of nature The professor knows his topic and shares his enthusiasm. I've learned so much from this course. Spread across the globe, this lecture series describes and explains many of the earth's most incredible geologic formations. I highly recommend this. It requires no knowledge of geology beforehand. Wysession explains everything you need to know to understand. Great job!

Rated 5 out of 5 by from Excellent Presenter More of a travelogue than strict geology. Much content on geological processes, but little on the actual geology of rocks. Still a very interesting course with lots of very good visuals, given by an excellent presenter. I enjoyed it thoroughly.
