Strange Log Appears Far Above Other Logs When Hanging Section on Selected Stratigraphic Horizon

strange_log_01

If you’re hanging a section relative to a stratigraphic horizon within RockWorks16, and you see a strange log floating way above all of the other logs, here’s what’s going on …

The offending borehole does not contain any reference to the stratigraphic unit (in this example, the top of the Potosi Formation) that was selected as the datum.  As a consequence, it remains at it’s correct structural elevation while all of the other logs have been vertically offset such that the datum contact is adjusted to an elevation of zero.  In other words, the program is working just fine – but a fat lot of good that will get you.

Here’s the solution …

Step 1.  Zoom in on the offending log …

Step 2.  Make note of the log ID.  In this case, that’s “DH-05”.  This, of course, assumes that you have elected to plot the log titles within your cross section.  If not, turn on the titles and try again.

Step 3.  Uncheck the offending log within the Borehole Manager database.

4.  Re-run the cross-section program …

5.  Be happy.

 

Columnar Sprites

Sprites (Wikipedia): “Sprites are large-scale electrical discharges that occur high above thunderstorm clouds, or cumulonimbus, giving rise to a quite varied range of visual shapes flickering in the night sky. They are triggered by the discharges of positive lightning between an underlying thundercloud and the ground.”

August 2nd, 2013 Antelope Canyon Flooding

David Rankin’s incredible video …

This is the same canyon that is an international destination for photographers (and a marriage proposal site for some geologists).  Check out these stunning photographs by Gregory Boratyn …

Fortunately, this flood did not cause the same fatalities as the 1997 event.
