Having worked at Hanford for more years than I should have, I can tell you that a "nuclear safety engineer" working there would be an "engineer" in name only. If Morgan really is a licensed mechanical engineer, then he is sorely underemployed. Nuclear Safety Engineers normally have no special education or qualifications. They mainly operate and maintain radiation counting equipment. It is extremely unlikely that he would have any qualifications in geology.
Living in the Richland Washington area, Morgan should be very familiar with geographically widespread "wave patterns" in soil and sediments caused by catastrophic flooding, not only in sand and sandstone, but in any number of soils. Richland lies in an area that was periodically flooded catastrophically by waters from Glacial Lake Missoula.
http://en.wikipedia.org/wiki/Glacial_Lake_MissoulaThe channeled scablands and huge soil wave patterns that were created by these floods can only be appreciated from the air. Since such flooding events were widespread in an area of well over 1000 square miles after the last ice age, Morgan should know better than to ascribe these kinds of geological deposition patterns, whether in Utah, Arizona or Washington State, to a global flood.
These patterns are created by flowing water as in a catastrophic flooding where great amounts of soil and debris are transported. They can also be formed on a lake beach or at a seashore by constant wave motion. Problem is, they don't look anything like the formations that Morgan is talking about.
Morgan's claim that only a "tsunami" 200 feet high could have created the patterns as shown in the article is pure bs. The formations are ancient sand dunes that and the patterns seen were formed primarily by the action of wind on the ancient dunes.
There is no reason to expect that these patterns would be found everywhere on Earth as a result of a global flood. Yet the article indicates that the young Earthers believe this is the case.
