Another reason all engineers are moronic assholes: They think the entire field of geology can be summarized by: “its either a rock, or sand, or silt, or clay....nothing more.”
Let me put it another way, check out this awesome picture of the Jurassic Aztec Sandstone as it is exposed in a beautiful slot canyon (a favorite rock unit of anyone living out west!):
to an engineer this sandstone can be summarized like this:
poorly graded sand, indurated, has a strength of 25.
to a geologist:
a well sorted, medium grained sand. the sands have frosted grains and indicate that it was deposited by the wind. The wavelength, width, and geometry of the crossbeds can be used to determine windspeed, direction, and duration of sand deposition. The colors indicate the movement of groundwater through time. The scalloped and undulating outcrop patterns describe the method of its erosion. the slot canyon itself provides a direction and pattern of fracturing of the rock, its stratigraphic position with other rocks place it in temporal context. Its lateral juxtaposition with other rocks tell you where it was relative to mountains, to the sea, to other areas. fossils within it tell you its age, etc...
I could go on and on...There's so much contained in rocks, the story of the earth, a picture of the past, a story of how the earth came to be the way it is. Geology is truly more than sand, silt, and clay.
And I know what you fucking engineers are thinking: "Joe, who gives a shit about long flowery rock descriptions, how does knowing its age and where the wind was blowing 250 million years ago help me write this report?"
Well Mr. Engineer, all of those flowery descriptions, placed in context can be used as a predictive tool: knowing the stratigraphy can help you determine what you will expect to see in your next bore hole, and may help you determine if you even need to pay for the next borehole. The wind direction and crossbeds may influence groundwater flow, contaminant transport, and might indicate how to plan for seasonal fluctuations in the water table. fractures and patterns of fractures can help you with rock strength, and help you predict potential failure zones. Understanding the change in crossbed angles from deposition to compaction and lithification can tell you about strength, blah blah blah.
The point is, is that there's alot more to the story than an engineer can understand.
The fact that engineers can't see beyond sand, silt, and clay is probably the reason so many of them are loser creationists. Seriously. Go look on Answers in Genesis, or on the Discovery Institute websites....both of this bogus asshole creationist websites are chock full of "science" articles written by engineers who think they know what geology and biology are.
engineers, while being book-smart at times, have no concept of the scientific method, understanding the value of descriptive data, and have no idea how other scientific disciplines can provide valuable insight into their little bullshit projects.
