HPT 101: Lesson 5: The Compression Event
In this lesson, we learn about the sliding of the continental plates at the end of the Flood phase, which we call the Compression Event. During this event we see massive sliding, cracking, and folding of the plates, plus the melting of the inner earth and the creation of magma near the surface.

Here is the template page you will need to print out: HTP101 Lesson 5A template page
NOTE: This video does include some actual HPT details, not just prerequisite stuff.
ALSO NOTE: I need to make a correction about crossover depth. Dr. Brown changed the estimate from 400 miles to 220 miles. I was using the old 8th edition and wrote down 400. Please change it to 220. I will correct the video when I have time.

Suggested activities for this lesson:
Activity 5.1: Watch flexible sandstone (itacolumite) bending

Activity 5.2: Do the sliding towel experiment!
You will need a bath towel and a very slippery surface. Think of some variations of your own, like a two or more towels stacked together, or a wider area, or an interesting starting condition like a heavy object sitting on the towel. Perhaps you might even analyze your final result each time and try to see if it matches any place on the globe.
Activity 5.3: 4-minute field trip to Uluru Rock in Australia
Uluru (also known as Ayer’s Rock) is most likely a liquefaction mound produced during the Compression Event. Here is a very short video showing what it is like to visit Uluru. (I don’t support the superstitious beliefs of the natives, but I agree in showing them respect because they were the first to claim possession of the rock, many centuries before the arrival of Europeans.)

SUGGESTED FOLLOW-UP ACTIVITIES for students using this course for credit:
READING: Read the chapter titled “Liquefaction: The Origin of Strata and Layered Fossils”
You should be able to read and understand everything in this chapter, since we covered most of it in our video lessons. There will still be some new information, though, such as the list he gives under the heading “Testing the Theories.”
VIDEO: Mainstream explanation of how Uluru (Ayer’s Rock) formed.
Here what Australian children are told about the formation of Uluru Rock. Be on the look-out for the Uplift Fairy Wand being waved at the landscape. Also, do they explain where all the water came from to form the temporary “inland sea”? Does he explain the holes on the sides of the rock? Is there any explanation given as to why there aren’t any similar features in this area? (All that uplift produced only ONE mound? The surrounding area is flat as a pancake!) How does this explanation compare to the HPT explanation? Would HPT have a problem with the explanation of its color?
VIDEO: Another creation scientist talks about the Great Unconformity (18 min.)
This interview with Dr. Steve Austin (creation geologist) is well worth your time. Compare and contrast his explanation of the Great Unconformity to the HPT explanation. You will find many similarities and a few differences. (Dr. Austin believes in a global Flood of immense power, but he does not think that most of the flood water came from underground. He thinks that water sloshing about on the surface did all the work of erosion, not powerful jets of SCW coming from below.) Here are some questions to consider as you watch:
- Does Dr. Austin agree that the Flood was global and did massive destruction, moving continents and creating all the sedimentary layers?
- To what does Dr. Austin attribute the flatness of the granite layer right under the Great Unconformity?
- Does this Unconformity extend beyond the Grand Canyon?
- What physical laws of fluid dynamics and sedimentation does Dr. Austin use in his explanation of why we find sequences of rock (sand/shale/lime, sand/shale/lime, etc.)?
- Both Dr. Austin and Dr. Brown agree that the sand in the Tapeats Sandstone layer came from granite that got pulverized in the flood. How does Dr. Austin imagine this happening? How does Dr. Brown imagine this happening?
- Does Dr. Austin admit that some of this sand came from distant sources? Does he think from the east or the west? Would Dr. Brown agree?
- Dr. Austin is an expert on mud flows. He has observed them, measured them, timed them. What is his estimate of how fast they can move underwater? Would he agree with Dr. Brown that the geologists who say they can move 60 mph are wrong? (Remember, they had to say the flows moved this speed in order to explain the snapping of underwater cables during an earthquake.)
- Would Dr. Brown agree that there were probably massive mud flows during the Flood Phase?
- Would Dr. Brown agree that there was probably some erosion of the granite surface (during the Flood Phase) right under the Unconformity line?
- Do both Dr. Austin and Dr. Brown agree that here isn’t any “missing time” in the Great Unconformity?
