Michael Oard  •  August 18th, 9:00am to 11:30am


Michael Oard returns as our speaker again this year for the month of August!  Michael Oard will give a detailed presentation on the Big Horn Basin, and show us not only how to interpret it in light of Noah’s flood and the post-flood Ice Age, but also how the Big Horn Basin is a showcase for the success of such an approach.

As Creationists, we should be viewing the rocks and fossils and the surface features of the earth (the geomorphology) from the biblical worldview. In order to do that, we need to understand Noah’s Flood from Genesis 6–9 and Psalm 104:6–9. The two mechanisms of the Flood are: “all the fountains of the great deep burst forth, and the windows of the heavens were opened” (Genesis 7:11, ESV). As a result, rain fell 40 days and nights on the earth. The beginning of the Flood was very catastrophic. So, we can think of Noah’s Flood in terms of a flash flood: one with a fast rise, followed by a slow rise to a peak, and then a slow drop in the flood water with sheet flow transforming to channelized flow.

When we compare to the Flood to a flash flood, we can graph the Genesis Flood into two stages: the rise of the Flooding Stage and the fall of the Retreating Stage after a peak at 150 days (Figure 1). Based on a flash flood, we can further subdivide the two stages into five phases. This is the Flood portion of the biblical geological model of TasWalker (1994) of Creation Ministries International in Australia (creation.com), which we can apply to almost any location on earth (Oard and reed, 2017), including especially the Bighorn Basin.

The Bighorn Basin in north-central Wyoming and parts of Montana is 120 miles north-south and 70 miles east west, and one can see all aspects of the Flood in a small area, including bonus features, such as the Heart Mountain slide and dinosaur tracks. Even Creation Week rocks and the Great Unconformity carved on these rocks can be viewed up close just west of Cody and at the tops of the Bighorn and Beartooth Mountains. About 5,000 feet of Flooding Stage rocks were laid generally horizontally on Creation Week rocks and the Great Unconformity.

At the peak of the Flood, the Retreating Stage started, which was mainly an erosional event with differential vertical tectonics according to Psalm 104:8a (ESV): “The mountains rose; the valley sank down”. Such differential vertical tectonics caused the Floodwater to drain from the rising continents and into the ocean basins. At the same time, the Creation Week and Flooding
Stage rocks buckle and tilted with mountain uplifts of 23,000 to 33,000 feet relative to the same rocks that sank in the Bighorn Basin. At the same time, most of the Flooding Stage rocks were eroded off the Bighorn Mountains to the east and the Beartooth Mountains to the northwest by “sheet flow”, but little erosion occurred on the Owl Creek Mountains to the south. The Absaroka
Mountains to the west are unique in many ways and heavily eroded. The eroded sediments from the mountains and upcurrent flow filled up the Bighorn Basin with thousands more feet of Cenozoic sediments, which have oil deep down and a little coal near the surface.

The Floodwater runoff then channelized and shifted to a flow northward down the Bighorn Basin, eroding perhaps 3,000 feet of valley fill sediments and sedimentary rocks. The sheet flow and channelized flow during the Retreating Stage caused erosional features that uniformitarian scientists cannot explain: such as planation surfaces, tall erosional remnants, water gaps, pediments, and long transported quartzites from central Idaho.

After the Flood, the Ice Age began with several Ice Age features that show up at the edge of the Bighorn Basin, such as end moraines, outwash terraces from ice melt, a U-shaped valley, and evidence of a small dam breach. The Bighorn Basin is truly a monument to the Flood and the rapid post-Flood Ice Age!
