I have a .las file (please see attached) that shows "null" when i tried to "Create LAS Dataset" in ArcGIS. I have followed the procedure I think I should but it still doesn't work. Please, could you look at the file and perhaps see what may be wrong. 

Thanks in advance

Hi Andy,

I think the LAS file is corrupted.  I tried adding it to ArcMap 10.6.1. and received an error:

Attached is a LAS file you can test with that works.

Thanks alot Skinner. I appreciate your response. I was also able to open the sample LAS file you attached for me here.

The LAS file I am trying to open is actually from borehole logging equipment (Delta Epsilon Instruments Inc.) and with this standard (CWLS Log ASCII Standard - Version 2.0).You may wish to look at it again in light of this additional info and with your wealth of experience.  It is a valid LAS file, but perhaps some manipulations were needed to successfully load it into ArcGIS. I say this because it was successfully loaded in IHS kingdom (a Geological Interpretation software).

I 'll be glad to get a response on this if possible.

Thanks all
